AutoCAD: Draw Walls Using the MLINE command

Plain AutoCAD can draw walls too. You Just need to learn how.
Català - Castellano - Deutsch
AutoCAD has a pretty unknown command called MLINE that allows you to draw Multilines. Multilines are ideal for drawing walls in plain AutoCAD. You simply need to create the wall style through the MLSTYLE dialog Box and then draw the wall as you would draw a line. See the dialog box.


And a MLINE I created to represent ta wall section.



MLINE Objects do not cleanup automatically with each other like AutoCAD Architecture Walls. There is a dialog box accessible via right clicking an MLINE and selecting Multiline Edit or simply typing the command MLEDIT that will let you choose how do you want the Multilines to join/cleanup between each other. This is the dialog box.


An this is how from an uncleaned intersection between two MLINEs.


You can get a nice cleanup, in this case using the Merged T intersection.




See that to create this multiline wall I used a special linetype to represent the Insulation. You can get it for a small Paypal payment. (email delivery)

AutoCAD Architecture: Tutorial on Wall Cleanup Priority

Which wall style do you want to prevail over the others?
Català - Castellano
An important parameter to be able to control when working with walls in AutoCAD Architecture or ADT is the Wall Cleanup Priority. What this parameter controls is basically which wall, or which elements of a wall are going to be shown on top of others when two walls meet.
To easily understand what I mean lets see a quick example. We create a wall style that represents the Structural walls of our project with a solid fill, very simple. Then we intersect that wall with another one, we´ll use the standard style. This is the result we might get:What we actually want though is for the structural wall to be always visible since it makes no sense that a non structural wall breaks a structural one. We need to edit the wall styles. To do that we can select one of the walls, right click and go to Edit Wall Style. There we have to go to the Components Tab and be sure that the Priority of the Structural wall is lower than the priority of the Standard Wal
Once we´ve set the proper wall cleanup priorities for both wall styles, we will get the result shown below. Very easy to use.

#Revit 2012: Video on the Use of the new "Create Parts"

Revit 2012 has a new feature called create parts to be able to manipulate the parts of complex elements like walls.
Català - Castellano - Deutsch
Just learned about the existence of the Twitter Autodesk account @RevitWikiHelp that provides a lot of links to useful resources on how to better use revit.

I learned about @RevitWikiHelp when they mentioned one of my posts. Now I follow them and I think they will be a great source of new Revit knowledge.

If you followed all the information on the new features of the new 2012 version of Revit, you probably know of the new "Create Parts" feature. this feature is key to work with some elements like exterior walls without the need of using complex Stacked Walls. I'll leave you with the video on this topic, which I think is good enough for you to understand the power of this feature.

Remember you can also follow the Blog using the twitter account @cadaddict where I also post short tips and retweets about Software and Processes for Construction, Architecture and Design

Some basic CAD organization is necessary!!

You can0t work on a project with all your drawings on a single file, seriously, you are not a student anymore, and if you are, better start training for the real world.
Català - Castellano - Deutsch
I am lately working more often with BIM than I am with CAD, but recently opening and analyzing some CAD drawings recieved from an architect made me think about writing this post. The thing is, while there might be no way to organize a CAD (or BIM) project without any flaws, there are some basics that I find essential if you want to keep certain quality standards and ease of use.

If we talk about quality, there is a basic standard people should aim for, and that is about consistency of information between drawings. That is, if two walls are 6,50m apart in one drawing, the same walls should be 6,50m a part in another drawing. Does it sound too basic, well, believe me, I've seen very basic drawings not accomplishing even that. The reasons might be many, but, as I see it, you can't expect quality if you have ALL YOUR PROJECT DRAWINGS ON A SINGLE FILE AND WORK ON THIS SINGLE FILE!!
Sorry for the shouting, but this has been making me waste a lot of time.

Why would you work with all your drawings on a single file? I have no clue other than "because you haven't thought about a better way". Let's ask ourselves a few questions. If we work with all project drawings in one CAD file:
  • What happens if you want to split work amongst two people? You can't.
  • How do you check that columns, walls on other buidling elementsare on the same position in all floorplans? Well I assume you basically draw some help lines and go check if they allign, but doing this you only check in one direction...
  • What happens if you accidentally delete, loose, can't find or get a Fatal Error on your AutoCAD file? Well, instead of loosing or having to redo information about one floorplan or elevation, you might need to redo stuff in ALL your drawings
I guess I could come with even more questions that should make those who work this way stop and look for an improved process. I have work in quite big projects over the past 4 years, and none of those projects could be done having all drawings in a single file.
If you are an All Drawings in One File (ADIOF) Architect, maybe you think your projects are small enough to not require a file organization standard, well you are wrong. Any project works better if you split files. My little list for ADIOF Architects of what you could do as a minimum to increase quality and workability of your drawaing standards:
  • One file, one drawing: Anytime corrections need to be done you could have more than one people working on it
  • All floor plan drawings are on the same position in each drawing: this way you can easily use the other drawings as XREFs (External References)to check the consistency between them (the same way you would have done long ago putting one drawing on top of the other using transparent paper)
  • Use the same prefix for all files of the same sort (FL for Floor plans, EL for elevations, etc): This way your project folder will be organised by type of drawing.
  • Use a single file inserted as an External Reference for those elements such as column grids, elevator cores, stairs, etc that go vertically through the building: instead of modifying those elements once in each drawing, you will save time by changing them once only.
I think only with this 4 points, a project can start being something more workable, and checking consistency between drawings is simplified quite a lot. There are many more ways to improve how people work with CAD, but this came to me as the most basic file organization points everyone should follow.

Revit Architecture: Louvers in Curtain Walls

How do you create Louvers in Curtain Walls
Català - Castellano - Deutsch

A nice video on how to create Louvers on courtain walls. I am not sure if this is the optimal method, but it seems to work like a charm. It basically creates the louvers by creating a panel with a curtain wall pattern. See below.



I am trying to figure out if something similar can be done to create metal doors with louvers, will post about it.

Is this the best way to do it? Would you do it differently? Comment below, we will all benefit.

AutoCAD Architecture: Irregular Walls - Endcap Tutorial

Learn how to use Endcaps. They are very useful when you want your wall openings to be more than just a square.
Català - Castellano
We have been designing a "not very modern" type of building (to say something) in the office. One of the things we have to deal with is the fact that this Gothic-Art Decoish building will have heavy pilasters on the façade to resemble some sort of old architecture.
In previous phases of the project we had been just using regular walls and adding the extra depth of the pilasters with an AEC polygon. Since we were printing with both wall boundary and wall hatch in black, that worked good enough for representation, but it was a pain in the ass when editing the wall, moving windows,etc.
On the current phase, we are reverting to a different kind of representation following more the standards set in the office. This means black boundry line + grey hatch for the wall. The problem is that if we use a regular wall and we add a AEC Polygon to the outside of it to get the extra thickness needed, we will see the line separating the wall and the AECP, and we do not want that.
The solution I found for this problem is to use the Wall Endcaps. But let´s start first with a picture of what we want to achieve.


As you see, we have a regular wall and some windows, but we want the space between the windows (what is the name in English for that?) to have the shape of the white line. To do that, we first increase the thickness of the wall to reach the thicker point necessary. THen we select the wall, right mouse click and select Endcaps --> Edit in Place. We will access the endcap edit mode. Endcaps work exactly as AEC Polygons, so take a look at this post on how to edit AEC Polygons. In the image below you can see the endcap after being edited in the Endcap Edit in Place Mode.



But when we exit, we see that the Window sill is showing like floating (this is because the window sill is showing the actual thickness of the wall). We have to edit the window style to fix this. Right click the window --> Edit window Style (if you just want to edit one window of this style you can pick "Edit Object Display")


In this dialog, we have to edit the Sill Plan. Click on the box to the right of the Sill Plan and go to Edit Display Properties on the upper right. In the following dialog we need to click the "other" tab. Here is where we will set how much we want the Sill to be recessed from the wall edge to show the way we want it. In our example we need to set the B dimension to -0.10 (negative will make the sill be recessed)


The final result is the desired. See the image below for the final wall with its irregular shape and the sill aligned to where we wanted.

Revit Bugs: Things that Revit Stairs don't do right #01

Every day I try to use Revit for Construction I see more and more how it has been completely thought mostly for design. Is that really BIM?
Català - Castellano - Deutsch
I still consider myself pretty new using Revit (less than 2 years experience and only 4 and a half projects), so when I am writing a post complaining about some of the things that do not work properly I try to check twice that they really don't work. If what I say is wrong, and you know the way to do it, please share here.

As far as I have managed to play with stairs, they are one of the family types lacking the most needed functionality. Since I am using revit for trying to get estimates, in my case the main functions that do not work properly are the following.

Area calculations for Stairs and their materials: to be able to get estimates of the costs of monolitic stairs (the most common one made of a concrete structure plus a paving materia for risers and threads) we need to be able to calculate the area of concrete that the stair has, and the area of paving materials.

Using the area of the concrete slab of the stair and landings as a unit might be a local thing, but this is how we do it here, so obtaining cubic meters of concrete slab is not what we need. I haven't found a way to obtain that, so stairs are one of the things I need to measure manually still when obtaining quatities from a Revit Model. I know I could paint the lower part of the stair with a different material, but I would rather have Revit handle Information better than that if it can. And my question at this point is Can it? If it can, please do let me know.

Second point on the list. Stairs have pavement material for threads and landings and another (or the same) material for risers. Although I can calculate riser and thread material surface by using the Width, Minimum Thread Depth and Actual Riser Height values to make some calculations, this is not good enough for landings would not be counted properly. I tried to obtain the materials from a Material Take Off Schedule, and relized Revit counts that wrong. Let me show you how wrong. Imagine a Stair that has 20 steps 0.28m deep and 1 meter wide. The easy calculations Depth x Width x Number of Threads gives us the Paving Area of the Threads. 19 x 0.28m x 1m = 5.32m2. Now lets see how Revit does calculatin this right? See the image below.


Surprise, Revit is giving me for that stair a Thread Material Area of 10.69m2, slightly more than double what it should give. What happens with Risers? The same my friend. 20 risers x 0.175 m (riser height) x 1 m (width) = 3.5 m2. As you see on the image the are that Revit counts ii twice that plus a bit more.

After playing with it a bit I realized Revit is giving the Area as the addition of the 6 faces of each thread or riser, so it is counting the area it should twice, plus adding the 4 side faces of risers and threads. Just wrong and useless.

Another thing stairs are lacking is the capacity to behave like floors (when monolitic, that is what they are). This is needed so they can enclose rooms and walls can get attached to them, right now as far as I know this can't be done, so it needs improvements.

Anyone thinks I am asking impossibles or knows of a way of doing all this that I am missing?

New Version of VisualARQ Architectural Tools for Rhino

New Version of VisualARQ for Rhino.
Català - Castellano - Deutsch
The friends from VisualARQ just sent me an email with the news that a new version of their Architectural Tools for Rhino is now available. VisualARQ is a set of tools that for what I have seen and read seem to turn Rhino into a more "Architectural Representation Friendly" software if that term exists.

The Tools allow Rhino to identify objects as windows, walls, etc. Much like regular BIM packages do. See a description of features here. The new features in version 1.2 can be found following this link.

In short, the new features are:
  • Beam object
  • Context help
  • IFC 2×3 export
  • Plan visibility can be specified per object depending on its position on the level.

Did I say BIM like objects? IFC 2x3 support? Well here you go BIM scheptical people. Even Freeformparadise (that would be Rhino) seems to need BIM standards objects and interoperability. The BIM steamroller is unstoppable...remember Stuart Brand's Quote "Once a new technology rolls over you, if you're not part of the steamroller, you're part of the road". What will you choose?

Revit Basics: Hide and Unhide Objects

How do you hide and/or unhide walls or other objects
Català - Castellano - Deutsch
I wanted to hide a wall to be able to see the imported linework below. This took no effort to find out. Simply select the element you want to hide, right click and select Hide --> Element on the right click menu. (it can also be accessed via Ribbon)



See the Element i wanted to Hide, the Wall, and once hidden how I can see the linework imported.


To Unhide Wall, Windows or any other Elements Hidden we need to activate the "Reveal Hidden Elements Button. It is on the lower left of the view.


This will alow us to enter the Hidden Element Reveal interface, where hidden Elements are shown in Redish color and others are faded in Grey.


Then selecting the element and using the right click menu, or using the button on the ribbon, we can unhide them.


The same procedure can be done hiding elements by category instead of single ones, or using filters. We will see that on another post.

SketchUp Plugins: Create Custom Windows / Curtain Walls

Easily create Windows with a Plugin that works as good as windowizer but that will do any window shape or custom design.
Català - Castellano - Deutsch
I wrote not so long ago about Rick Wilson´s Windowizer Plugin to create Windows from a face. Windowizer is great, but it only creates windows based on a regular grid (number of rows - number of columns).
TIG's Latticeizer (Laticeizer.rb) does what Windowizer 3.0 can't. It creates a window with it's mullions and glass parts from a series of faces, cleaning up the intersections very neatly. See how from this set of faces (all faces have to be coplanar) i easily created a custom window.



All faces need to be coplanar and need to be Grouped. The dialog Box will let yo choose the settings, sizes, colors, etc. Pretty Cool. Thanks TIG!!

Select Similar Objects / Blocks / Components

Learn how to select all the instances of a component
Català - Castellano - Deutsch
I post often how to find ways to mimic behavior of different programs. We get used to certain tricks that make us work fast and then we miss those things when using a different software.
This is the case of the AutoCAD Architecture function "Select Similar". What this does is to select all instances of an object with the same properties. For instance, if we select a wall, right click and choose "select similar" in the context menu, all the walls of the same style on the objects layer will be selected. The same happens with any object sharing properties and layer with the selected objects.



So how do we do this in SketchUp? There is actually not one method that does all this, but there are several ways to achieve a similar result. If what we want is to select all the instances of a component (the equivalent to Blocks in SketchUp) we need to open the component browser (Window --> Components), then right click the thumbnail of the component we want to select and choose Select Instances (we already went through this on a previous post about How to Replace all instances of a Component).
If what we want is to select all the objects on a Layer, we can simply select one object that lays on that layer, right click it and go to Select --> All on same Layer.

These tricks on SketchUp don't do exaclty the same as the very useful "select similar" command of AutoCAD Architecture and the other AEC versions of AutoCAD, but they are close enough.

AutoCAD: Select all Connected Geometry.

Wonder how to select with a single click all connected geometry? AutoCAD can do it, you just need to know the right command.
Català - Castellano - Deutsch
Usually my day at work involves designing and drawing both in AutoCAD and SketchUp (and eventually in Rhino depending on the complexity of the geometry of the project). Switching back and forth from one software to another makes you miss on one program some of the functions that the other program has. This was the case of the "Select all Connected" option in SketchUp. It is so useful to select all connected geometry (it can be accessed through a right click menu or by triple clicking any line on the drawing). But can something similar be done in AutoCAD? The answer is yes.

There is an Express Tool for AutoCAD called FASTSEL (accessible also via the FS shortcut) that allows us to select all the geometry that is connected (touching) any element on our drawing. The elements that can be used using this commands are LINE, POLYLINE, LWPOLYLINE, CIRCLE, ARC, ATTDEF, TEXT, MTEXT, ELLIPSE, SPLINE or IMAGE objects. BLOCKS or XREFs containing these objects will also work.
AEC Objects from some of the vertical products such as Walls or AEC Polygons are not supported. In case you have a Block or XREF containing both supported and unsupported elements, the command will only use the supported elements.

The command can be accessed transparently while using other commands by typing 'FS while the command is running. Also, use the FSMODE System Variable to control if the FS command selects all connected geometry (FSMODE = ON) or only the geometry connected to the first object (FSMODE = OFF).

Note that this Express Tool Command is mostly intended for 2D since I tried to use it in 3D and lines that are actually not touching other geometry did get connected. I find it specially useful when I accidentally explode polylines, with this command you can select all the lines that where previously connected with a single click. Select faster than a private jet with this express tool!

Rhino Plugins: VisualArq - Architectural Tools for Rhino

Need some ACA like tools when using Rhino? This might be the Plugin you are looking for.
Català - Castellano - Deutsch
Rhino is a great modeling software, but you will agree with me that when it comes to simple tasks like creating Walls, windows, Stairs, etc. it is not as efficient as AutoCAD Architecture or SketchUp (specially if you have the 1001bit tools Plugin).
Well that might change if you add to your set of Plugins the VisualArq set of Architectural Tools. This set of tools aims to improve the work speed for Architects, Interior Designers, Etc by adding a set of Parametric Architectural Objects and Documentation Tools.
I haven't had the chance to check it since I only have access to Rhino at work, but from the Gallery on the VisualArq website, the Plugin looks promising.
You will need Rhino's Service Release 5 to be able to use this plugin.

AutoCAD: Dealing with Ellipses

Ellipses are necessary but troublesome. Learn to deal with them appropriately.
Català - Castellano
If you have a Boss like mine who loves ellipse shaped Buildings, Drop-offs, Piazzas, etc. you probably have to deal with ellipses more than you wish. Ellipses are quite troublesome.
First of all they don't offset as ellipses, rather when we offset an ellipse the parallel geometry obtained is a SPLINE. Splines have the disadvantage that they can only be trimmed but not extended.

One way to partially solve this problem is to know the PELLIPSE system variable. The default value of this paramter is 0, which means ellipses are drawn as ellipses. If we set it to 1, instead of an ellipse the geometry drawn is a POLYLINE. The advantage of using polylines is that they can be exploded (Ellipses can't) and when offset they remain polylines. Another advantage is that Polylines can be converted to other types of objects (in ACA you can convert them to Walls, Spaces, etc).
The disadvantage of drawing ellipses as Polylines is that since they are an approximation of an ellipse made with multiple curved segments, if we trim part of the ellipse shaped polyline we will probably not going to be able to recover the old geometry by using the extend command.
Another consideration when deciding if you want to set PELLIPSE to 1 or 0 is to think if you will need to modify that ellipse often. If you will be trimming and extending segments of an ellipse my recommendation is to keep it in 0 (the ellipse is a "smart object" you will be able to recover all of its geometry from its smallest segment if is a real ellipse, if it is a polyline yo will have to redraw it) If you will be offsetting the ellipse better set it to 1 so you avoid getting Splines that will leave you with no flexibility.
Another issue I found when dealing with ellipses is when I want to redraw one that is not aligned with the active UCS. For some reason the "UCS Object" feature doesn't allign properly with the axis of ellipses. So, if you want to draw an ellipse using the same alignment for its axis as a previous one this is what you need to do.
You need to know the concept of Quadrant Osnap. In ellipses (and circles) quadrant osnap is a point on the ellipse that intersects the ellipse axis. See the three images below for a clearer explanation (click on the image to enlarge)

The image on the left shows a selected ellipse. The grips we see correspond to the centre and quadrant osnaps of the ellipse that we will use to get the righ UCS alignment. The image in the middle shows how we can access the Osnap contextual menu to select the quadrant osnap. (follow this link for more info on the topic). The image on the right shows the line from quadrant to quadrant drawn. We will use the align UCS to Object to this line to get the correct UCS that will allow us to redraw an ellipse equal or parallel to the original one.(This only works with Ellipses drawn with PELLIPSE = 0).

AutoCAD: Things that SHIFT can do for you

Do you know that the SHIFT Key can make your life much simpler?
Català - Castellano - Deutsch
After many months finding tips about how to work smarter and easier, I realized that some Keys in the keyboard really make a difference on your work speed. That is the reason why I want to start a series of posts explaining what some of these keys can do for you, to improve the way you work.
We will start with the SHIFT Key, since it is the one that so far has proven to me more useful. This is a quick list of how SHIFT will make you work faster with AutoCAD:
  • SHIFT while drawing a line will lock the perpendicular inference. It is like a temporary activation of the ORTHO mode. If you press SHIFT, a tooltip with similar to the macro Icon of digital cameras appear to show you that ORTHO mode is temporary active.
  • When using FILLET or CHAMFER, pressing SHIFT while selecting the second entity will override the fillet radius or the chamfer distances with a value of 0. Very useful if you want to keep certain radius or chamfer distance but once in a while you need a sharp corner.
  • When Selecting Grips of an object, holding SHIFT will allow us to select multiple grips (deeply explained here).
  • When we are selecting objects, pressing SHIFT will allow us to deselect any of them.
  • When using TRIM or EXTEND, pressing SHIFT will toggle between one command and the other (i.e. if you typed TRIM and press SHIFT and select the object, it will extend instead of trim).
  • For object snap tracking, object points are automatically acquired. If you press SHIFT you will avoid acquiring points for object snap tracking.
  • SHIFT + SPACEBAR: cycle through selection peviews If selection preview is turned on, you can cycle through the objects by rolling over the object on top to highlight it, and pressing and holding SHIFT and then pressing SPACEBAR continuously. When the required object is highlighted, left-click to select it. If selection preview is turned off, hold down SHIFT + SPACEBAR and click to cycle through these objects, one after the other, until the one you want is selected. Press ESC to turn off cycling.
  • SHIFT + RIGHT MOUSE CLICK: Will call the Osnap contextual menu (see more here).
  • SHIFT + TAB: When working with Dynamic dimensions, it cycles backward through all editable dimensions (TAB only will cycle forward)
  • On AutoCAD Architecture, when we draw Walls, SHIFT allows us to choose the Justification Line. Once we started drawind the wall, by prssing SHIFT we will cycle throught the different possibilities (left, center or right)
I have to confess that 2 or 3 of these tips I never use them, but some others have become so fundamental to my workflow, that is hard to imagine how I worked without them for so long.
