I would be amazing to have referenced CAD files in FormZ. Similar to how texture maps works - they update automatically if the image source file is updated/changed.
To have a similar feature for CAD files would be great. For my purposes it would be referenced DWG files. This is a common feature of other CAD programs.
I draw a floor plan in AutoCAD (or Vectorworks, or Draftsight, etc) and export a DWG file. I import the DWG to FormZ with the option to make it a referenced file.
Then I make changes in AutoCAD, export as DWG again and the FormZ file is updated automatically.
The DWG import would need to be placed not the appropriate plane and be consistently relative to 0,0,0.
It would also be nice to have some control over the line settings upon import. However, if there was an option to place the entire DWG on one Layer that would also do the trick as one can set layer overrides.
Currently I have to reimport DWG files over and over again to match up FormZ with my 2D counterparts (in my case from Vectorworks).
