One thing I really dislike about Revit is the fact that it does not show projection lines at wall openings in a floor plan. Therefor, I am trying to ‘catch’ these openings’ locations, create a curve and insert a line based detail component (a dashed fill pattern). Then, it will be clear on drawings that a wall exists above these openings in the wall.
IMO, I have almost succeeded using Dynamo. However, I am stuck at the moment, hopefully you can be of assistance! I want to get the green lines as seen in the screenshot below.
This is what I have done thus far:
- I have made an intersection of the wall geometry with the location line of the same wall, which I have given a z-translation of 1200 (approximately the cut plane of my views).
- This results exactly in those curve segments which I am NOT interested in! See screenshots, lines in red color
This is what I think should happen next:
- Either change the geometry.intersect node to something like geometry.DOESNOTintersect node. Does this exist? Can someone make it?
- OR given the script as is, subtract the curves which I am not interested in from the Wall location line. That would leave the curve segments which coincide with the wall openings!
Thank you in advance!
