I do landscape and am researching to transition to Revit for better collaboration. I understand the terrain is best to be done with toposolid. I would plan also using toposolid for exterior hardscapes. The main reason is that this reduces switching from different tools, hence streamlining the workflow, and I can get contours displayed on the hardscape area.
I am not a pro user, but as far as I have learned, the toposoild functions the same as floors, I will have the same control over layer structure and graphic appearance. Scheduling-wise I think I can differentiate 'hardscape toposolid' from 'terrain toposolid' by customized parameters.
I think it may be a promising idea, putting this here just to see if there is any aspect I didn't think of or may not fly as I thought. Any comment is appreciated. Thanks!
