This might not he possible (But should be!!!) Trying to (re)Set drafting crop regions to tight in around elements in drafting view. The Python is intended for later introduction into PyRevit, so now everything is in one Python module.
Sometimes drafting views extents far exceed the actual contents.
(WARNING: Playing with the CropBoundary TRUE/FALSE is what “Blew out” the limits for the drafting views in the first place; hence the REVIT 22 source data attached : )
Sometimes like in this example there is “dead” space (RED FILL (5-7) Below)
Running the script doesn’t expand or contract the extent of the limits (RED DASHED LINES 1-4 above)
I wasn’t sure if min/max would take a “None” at the start - So the minPt and maxPt DEF() may not be needed.
The Limits of the bb crop are ‘stuck’ at (-100,-100,-100) and (100,100,100). Not sure but does the /BoundingBoxXYZ return the element or the view bounding???
