Design By Many

January 24, 2011

If you haven’t seen it you should head over to Design By Many.  It’s a new social modeling competition site.  Even if you don’t decided to compete for some of the awesome prizes in the sponsored competitions the submittal source files are free and worthwhile to download.  If you pick apart the models you are sure to learn a thing or two about modeling in Revit or other industry standard software.

The latest sponsored competition was to design an external shading element for a downtown Phoenix structure.  Apparently I couldn’t help myself one night as I started designing a solution.  It’s not perfect but you can see (and please vote!) my submittal here. I invite you to take the sail array models apart.  You will learn a thing or two about Revit families and 3D arrays.  I think I nested the sail family 5 families deep! My custom truss family is based on a 3D void shape which has extrusions along the void edges.  It makes for some very easy modeling of complex sweeps.

SARUG Meeting: Jan. 2011

January 23, 2011

Our January meeting is coming up on the 27th (at 5:30 pm) and will be hosted at the Breckenridge Group. As always we will record the meeting and post it to the SARUG Channel for you to view.

Andrew will be giving a presentation on how the Revit B.I.M. can be utilized as a platform for data linking to a remote WIKI. This topic arose due to a discussion of how the B.I.M. was not able to embed information like: manufacturer specifications, cut sheets, warranties, maintenance procedures and cycles, and other project critical information (most of which would take the form of a scanned pdf) This information needed to flow down to the construction phase as well as the owner with the B.I.M. We also wanted to know if a DWF would carry the web links for portability and free the data from the Revit file. This should be a very interesting discussion. The approach Andrew is taking can be utilized for multiple projects and can be accessed from any remote location. It also keeps a historical record of the data, which can often get lost over time due to manufacturer upgrades.

We will also have some family creation demos and hopefully a presentation on Revit MEP by Patrick, one of our group members.  Quinn will demo his famous Datum which gained him Guru status.

Also Steve has set up a relationship with CALA where we are supporting their Construction Documents Class as teaching assistants, which by the way is using Revit.  This is not a lecture assignment but more of a walk around one on one assistance.  While Revit experience is a plus we are also to provide guidance in the particulars of assembling a set of construction documents.  Classes are on M,W and F 11:00 to 11:50 am.  Currently Steve, Jake and I are assisting with at least one of us at each class. They could use more TA’s so if you are interested in getting involved please speak with Steve via email or at our next meeting.  

This type of assistive interaction with CALA has been a focus that Steve, Jake and I have had since the original inception of SARUG.  Thanks to Steve we are taking the first step into making that vision a reality.  I hope you can join us in the effort to strengthen the academic / professional bond within our architectural community through this opportunity and share your experience in B.I.M. (Revit) / C.D. production.  A skill set that is vital in today’s changing architectural practice and is an essential entry point for these students into the profession.

Revit 2011 “Element’s internal join data is corrupt” Error

January 20, 2011

This seems to be related to Revit Architecture 2011, Build #1.  If you run into this error check out this thread on the AUGI forum for some workaround suggestions.

Build #2 appears to address this issue, but be warned. Both Steve and I had our 2011 (build #2) Revit’s crash our systems.  My Revit wouldn’t even open so I had to do a reinstall.  Steve’s experience was worse.  He’ll give you the gorey details at the next SARUG meeting. 

Trouble? Shoot It!

I wanted to expand on this post since the forum link talked heavily about auditing.  The audit option can be found in the open project dialog along the bottom left (see above).  Select it to force an Audit while opening.  You will not get this if you use the open recent feature in Revit.  You have to go through the open project process.

April 16, 2011 Update:
I’ve also discovered that this error can arise from options.  I was attempting to cut a opening in an existing wall but there was an intersecting wall in my as-built options at the same location as my opening jamb.  I keep two as-built options one of the existing building which never changes as a permanent reference and another that acts as my demolition reference.  The error required me to “disallow join” in both of these options even though the existing building option was not set to primary.


The Avatech Channel

January 20, 2011

Tired of watching CSI reruns or political sparring between FOX & CNN?  Well I attended one of Avatech’s web casts, struck up a connection and discovered they have a boat load of  webcasts that you can access at:  Of course it might not be as entertaining but it will definitely expand your technical horizons.

Happy Viewing


Why Can’t I Use the “Count” Parameter in my Schedule Formulas?

January 19, 2011

Seems like a logical question.  The parameter is counting the items now I just want to use that value in my formula.  But wait Revit says you can’t!

Here’s a explanation of how to get around this idiosyncrasy.  With a completely counter intuitive process. 

Essentially you need to create a calculated value parameter, called let’s say “Total” that points to a parameter in your schedule that contains the value you want to multiple the count by and once the parameter is created you check the “Calculate Totals” box in the Schedule Properties “Formatting” tab for that “Total” parameter.

If that doesn’t explain it try this Link.
