Pad not Cutting Existing Toposurface

This issue comes up when you have multiple toposurfaces on multiple phases. Each phase has it's own 'hole' made with pads. Every other phase shows the pad cutting a hole in the toposurface except for the Existing phase. This happens when there are multiple toposurfaces occupying the same physical space but on different phases. The only workaround that I have found is to use the Split Surface tool, cut the shape of the hole (pad) and then delete it.

Revit 2012 Edit In-Place Family Faint Lines

When you edit or create an in-place family the "Halftone" setting is applied to the other linework in the View. The effect of the "Halftone" settings can be adjusted in the Manage Tab-Additional Settings-Halftone/Underlay dialog.  If you feel the linework is too faint, you can adjust those settings by sliding the Brightness slider to be darker.

Thanks to Kyle from Autodesk for helping me with this one.

Uninstall Autodesk Building Suite 2012 Ultimate

It's great that we can install 15 programs with one click but what happens when (not if) we have to uninstall? A colleague just sent this link to me for that very reason. Only issue is that the application will not uninstall the Revit and Navisworks portion of the suite. You will have to do that the conventional way.

The uninstall application...

Roof Tags

There are no default roof tags that I have found. So here's how you make one in three easy steps:

1. New Family
2. Choose the Generic Tag template
3. Change the Category to Roof Tags

Dimensioning to 'Center of Core' in Linked Wall Doesn't Work

I think that the title says it all. Why is this important?

Many of you are using linking on large multi-discipline projects. You will link all of your models into one 'documentation' model. If you cannot dimension to 'center of core' of a wall through a linked file you are missing a key documentation feature in the workflow.

(Nasty) Workaround:
You will have to draw and lock ref planes at the center of core in every wall, in every link. Then you will be able to dimension to the ref plane. ugh.

Autodesk Development is aware of this and plan to fix it. But to add some urgency, please contact Autodesk through your Subscription Center account or your local reseller and log this. If you have a better workaround please feel free to comment...

View Filter: Footings etc.

Make a View Filter if you would like to show footing walls automatically as a hidden line. Here's how (in twelve easy steps!):

1. Visibility Graphics
2. Filters
3. Edit/New Button
4. New, call it 'footing'
5. Pick the Walls and Structural Foundations Categories.
6. Filter by: Description
7. Contains: footing, OK
9. Select the filter you just made 'footing'
10. Override, Projection Lines, Pattern, set to Hidden, OK and OK
11. Select your footing  wall type, Edit Type, and edit the Description to say 'footing'.
12. Select any other footing families or wall types and repeat step 11.

Revit 2012 Hangs at Splash Screen or Crashes with Unrecoverable Error

from Revit Clinic post...

1. WSCommCntr3.exe Process
For 2012 products, the Autodesk InfoCenter launches with Revit as a WSCommCntr3.exe process in the Windows Task Manager. The Revit.exe process could potentially wait on this WSCommCntr3.exe process. If you find Revit not getting past the splash screen, open the Windows Task Manager > Processes > WSCommCntr3.exe > End Process.
2. System Tray Applications
Verify if you have an application installed on the workstation, which allow the ability or attempt to minimize an application to the system tray. One example would be 4t Tray Minimizer. If present on the workstation I would test temporarily ending the application \ process to see if Revit 2012 launches as expected.



3. Corrupt WSCommCntrData.xml File
If the WSCommCntrData.xml file becomes corrupt, Revit may hang when attempting to read it at startup. First verify the file exists at the location below and if so move WSCommCntrData.xml when Revit is closed:

Windows Vista & Windows 7 ...\Users\%username%\AppData\Roaming\Autodesk\Revit\Autodesk Revit Architecture 2012\ENU\Components\WebServices\WSCommCntrData.xml

Windows XP ...\Documents and Settings\%username%\Application Data\Autodesk\Revit\Autodesk Revit Architecture 2012\ENU\Components\WebServices\WSCommCntrData.xml

4. Corrupt UIState.dat File
This could also be potentially related to a corrupt UIState.dat file. While Revit is closed, move or delete the UIState.dat file at the location below:

Windows Vista & Windows 7 ...\Users\%username%\AppData\Roaming\Autodesk\Revit\Autodesk Revit Architecture 2012\UIState.dat

Windows XP ...\Documents and Settings\%username%\Application Data\Autodesk\Revit\Autodesk Revit Architecture 2012\UIState.dat

Revit Design Adventures: The Right Foot (2)

Okay, before you go and accuse me of plagiarising myself, let me explain. I am going to be documenting the process of this 'Flapping Roof' project. The previous post explains a little about our exciting next adventure. That being said, I want to revisit some of the things I consider to be very important to the success of our project. In two previous posts we discussed the things that you must do before you start drawing walls. I'm going to consolidate these into one post for this project.



Template
Project Base Point
Project North
Location
Levels, Grids and Reference Planes
Simple Material
Simple Wall, Floor etc styles.
Clean and Link AutoCAD

Why do we NEED to do these things first? Simple answer is because it's a pain to do these things once the model is in place. Let's start with Project Base Point.

Template

Choose the correct template for the units that you will be using for the project; metric or imperial.

Project Base Point
You can find this in the Site Plan view of the default template. It's a blue circle, ignore the blue triangle. Do not move either of these icons. Simply note that the blue circle, the Project Base Point is 0,0,0 and can never be changed or moved. When and if you export to AutoCAD the Project Base Point will line up with the 0,0,0 of AutoCAD. Draw, name and pin some Reference Planes at this point. As you can see in the image above I forgot about this and didn't adjust the linked dwg or my model. It didn't hurt us but I should have known better.

Project North
Once you have found the Project Base Point, click on it. You will notice that you can change the Angle to True North. Make sure that you do this in a Site view with the Orientation set to True North (found in View Properties). There was a north arrow in our as-built dwg where we measured the angle to true north.

Location
The location tool defines where your Project Base Point is located on Earth. This tool is found in the ribbon under Manage-Project Location-Location. Set the address as if you were searching for it in Google Maps. Setting the location will be useful for solar, shadow and energy calculations. If you are starting with an AutoCAD survey I would recommend you read this post I did a while back.
(http://revit.blogspot.com/2010/03/coordinates-base-points-surveys-linking.html)

Phases
Even if you think that you will never use Phases, set this up. The default phases are Existing and New Construction. The default current phase is New Construction. This can cause problems if you have modeled half of your existing building without knowing that it was put on a phase called 'New Construction'. Make a few phases, more than think you will need. Use simple names like Phase 1 or Phase 2. Fill out a brief description if needed. Get rid of the phase called New Construction, this will only confuse things. This project did not call for the use of phases.

Levels, Grids and Reference Planes
Always make the Levels first. Even if you're going to leave the levels as is you should be aware of their height. In this case we had an as-built section in dwg that we could match to.

Next we make some Reference Planes defining left, right, front and back. Always name the Reference Planes. This is found under their properties. Start drawing your grid If you know what it is going to be.

Simple Material

Phil Read gave the inaugural address at the Ontario Revit Users Group. He showed us a lot of crazy stuff but one thing that stood out was the following tip. Make a generic white material and apply it to everything (walls, floors, window and door frames etc.) This can help us and the client to focus on the major design issues instead of floor colours.

Simple Wall, Floor etc styles
Let's avoid defining things too much when naming Families. Adding materials and sizes to names of styles in Revit ends up creating more work and inconsistencies. 
Create an exterior wall type: EW-1, thickness is set to the overall wall thickness, material is 'white'.
Create an interior wall partition type: IP-1, thickness to overall wall thickness, material is white. Make a floor and roof in a similar fashion.

Revit Design Adventures: The Flapping Roof (1)

The Flapping Roof 

So it can be done in Revit. Was this ever in doubt? Maybe.

AGATHOM Co. is a Toronto boutique architect who only create masterpieces in my opinion. I don't know another architect that has a full working wood and metal shop on premises. They wanted to do a design study and also get an idea if Revit might fit into their workflow.

We needed to model the building as context but focus on the roof flap. This was beyond conceptual, it was intricate and detailed. It had to be parametric so the architect could raise and lower the angle so as to find the perfect slope and position for the beams. The main focus from a Revit standpoint was to create a parametric roof flap family. During this series we will examine custom modeling, complex formulas in families, mistakes, bugs and generally pushing Revit beyond it's comfort zone. 

Our adventure starts with starting on the right foot by setting up the Revit file.

T-Shirts In Honour of Gregory Arkin

One of my favourite Revit blogs is revit3D.com by Gregory Arkin. He never pulls any punches when talking about BIM vs CAD. So, in the spirit of good natured 'tool bashing' I have started a new line of swag with a nuanced slogan...until they shut me down that is.

What Do You Constrain Results

This poll was designed to get an idea of how 'constrained' people are going with their Revit models. The poll confirms to me that most try to avoid constraints as they become very hard to manage. I was surprised by the percentage of people attaching 2D details to the model. A very small percentage try to constrain everything. I would love to hear why.

BIM in Facility Management

Richard Peakock from FM systems will talk about how their FM software is taking advantage of the data generated in the Revit model and how it creates a bi-directional link between Revit models and a Web service. He will show how to connect BIM data from design, construction and renovation to facility management and operations, how to do manage Space inventory, allocations and occupancy in Revit Architecture.

Rich has over 23 years of experience in the Facility Management and Architectural industries. He has been involved with CAFM and IWMS implementations including consulting, configuration and technical capacities, as well as business development and strategy.

Revit Design Adventures: Billing on Day 5 (22)

Okay, let's speed this up a bit. Here are the final two sheets of the set. Details and Elevations. I already spoke about the detailing process in an earlier post. So let's get on with time and billing. No spreadsheet needed. The project took about 10 hours of billable time. A couple hours of on site measuring for confirmation, a couple hours of as-built modeling and setup, an hour of renderings, and a few more for proposed modeling, detailing and sheet cleanup. Throw in a client meeting or two and you have the ten hours. Revit projects are weighted on the setup and modeling side of things. The documentation still takes time but hardly any in proportion to modeling. 


Lessons learned:
There are lots more services we could have offered this client like quantity takeoff and construction management but the client wanted to do it themselves (can you blame them?).  
Always model where possible. Yes, it took us some more time to model the skylight wells in the first iteration but in the end the client made a very fast decision when they saw the result.
Model it like it's built. 
Don't detail too early. I didn't show it but we changed the roof thickness a few times which meant updating the detail components more than once.


Well, I think it's time we moved on to another 'adventure'. Make this real model into a Revit model. Oh, and make the 'roof flap' parametric.
