I decided to create this post to explain what is really created when you use the ImportInstance.ByGeometries Node in DynamoBIM….
as shown per this blog post regarding 3D Room Geometry.
It turns out the ImportInstance.ByGeometries Node does the following
1. creates “3D Geometry” as an exported .SAT file
2. names the SAT file the element GUID
3. places it in a temp directory usually in your C:Users…AppDataLocalTemp directory
4 then imports the SAT file into Revit.
With all that said it is possible to change the name of the sat geometry elements such that it is not using the default “name”. Replicate the export/import sequence manually as shown in the image below in relation to the 3D Rooms Geometry example.
Clunky? Its better than no 3D room geometry. I agree that using imported 3D SAT files is not ideal but it is useful especially if you want quick geometry to be placed in Revit for spacial studies.
Thus, the 3D geometry/SAT import (as with all geometry imports into Revit) it is limited compared to a 3D family.
In future posts I will explain how to change the color of these SAT geometry elements and I will also explain how to place real Revit Families that represent 3D room geometry.
