i know i've asked this question before, but haven't really resolved the issue.
i have an existing ground surface.
i would like to build a surface depicting a concrete slab for a house. the house has a front stoop that is 4" lower than the slab.
it also has a patio out back that is 4" lower, and driveway down one side that abuts the house slab.
i know feature lines can't cross or be above each other in the same site. i've experimented with offsetting them by .01' which leaves a slight gap.
i've also tried creating individual sites and combining them, but that didn't work very well. again the lines that are in the same plane vertically react to each other with wrong results.
i've been building each part separately by offsetting by the .01' and setting the outside feature line to drape onto the surface, etc.
i plan to paste all the surfaces at the end to create a composite surface.
any ideas on how to achieve this a better and/or more efficient way.
thanks
