I am trying to create a toposolid in Revit using contours. I am close to a good result but some things are still behaving weirdly. For example, there are these jogs at certain locations:
It seems like they are happening where there is a large single ngon. In this case, I am confused about why revit is connecting the line at 807 to the line at 808 with the jogs parallel to the red.
I am trying to remove the contour that seems to be causing the jog (the inner ring on left image) and revit keeps crashing. toposolid-new.gh (437.7 KB)
I haven’t had a chance to look at the particulars of your contours but the Revit aspect is pretty straight forward. It will create contours based on the height of the points. If you are getting sharp areas that means there is a drop off in height that is being transitioned.
The subdivision sometimes doesn’t succeed depending on the dimensions of the cropped toposolid. I wonder if it fails when there are particularly extreme corner conditions like the image shows. It would be great if I could prevent that behavior at the corners. I think I need to somehow add points to the perimeter of the curves, where the trim is occuring.
In this project I will be doing a lot of landscape buildup on the site. These can maybe be created as new toposolids and joined to the existing one, regardless of the continuity being smooth or hard. Hopefully this will mean I don’t have to go back into the initial toposolid model and can work additively.
I’m not sure if it makes sense to keep wasting time trying to get an extra few feet of margin on the base topo.
