The scenario: you receive raw point cloud data, and want to process it in Recap (part of 2014 suite), export to PCG, and import back into Revit 2013.

Or: you request a PCG from a surveyor for Revit 2013, and they give you a “newer” PCG from Recap that will not import.

The error received in Revit 2013 is:
“Unable to create a Point Cloud instance.  The file may be an incompatible format or corrupt.”

However, if you index the same raw point cloud data using Revit 2013 built-in indexing, the resulting PCG will work fine.

It would seem that there is some difference between the built-in Revit 2013 indexing of PCG point clouds, and the PCG point cloud exporter in Recap.

Workaround:

  1. Process the raw data in Recap (requires indexing time)
  2. Export to PTS file
  3. Import the PTS into Revit 2013 (requires indexing time — again)

Most of you already know how highly I recommend Harry Mattison.  He is completely at peace with the Revit API, and he knows instinctively how to solve Revit coding challenges that are out of reach for most of us.

For less than $150, you can learn the Revit API from the master, at https://www.udemy.com/revitapi/

Harry was an employee of Revit Technology Corporation and Autodesk from 1998 to 2012 and spent four of those years developing and testing new Revit APIs in areas such as the Family Editor, Massing, Analysis Visualization, Dynamic Model Update, and Views & Schedules.

I have personally started reviewing the classes, and the level of expertise targeted by this course is very appropriate — intermediate to advanced Revit users, with a comprehension of basic programming techniques.  Not too basic, and not too complicated 🙂

Daniel Stine hosted the interestingly named RTC class:
Mastering Materials: Getting What You Want from Revit

In a recent Cadalyst article, he gives a few good material tips.  Here are just 3 of them:

1) Material Assets
Think of a material as a container. Some of the information represents elements you can touch and see when the building is complete, while some does not. Assets are modules, if you will, that better define a material. These modules are optional and can be added or deleted as needed; however, most materials have an appearance asset, which cannot be deleted.

2) Material Transparency in Elevations (vs 3D views)
In any elevation view, materials are not transparent, as you can see in the left-hand image below (regardless of what Visual Style is set to). Even turning off the glass material in a view’s Visibility Graphics Overrides (VG) will not allow you to see through the “opening,” as seen in the second image. The trick here is to edit the opening in the family so it is transparent in elevation, as shown in the third image.

To achieve that, simply select the opening and check Elevation on the Options toolbar.

3) Self Illumination
 A surface with a self-illuminating material will actually add light to a scene. In the image below, the self-illuminating low wall in the center of the room is the only light source. This material can also be used to get a very white surface when nothing else seems to be working.

In our case, we had to add local PC “Users” permissions for Full Control to this file:
“C:ProgramDataAutodeskApplicationPluginsADSK-IFCExportUI2014.bundlePackageContents.xml”

I recommend that you review each PackageContents.xml in the ProgramData location to check for appropriate permissions.

Other possible solutions:
  • Delete Autodesk, Inc. folder
  • Delete cascade
  • Make a new user profile and see if that works
