Proposed Surface boundary by AI.

[joantopo]

As I Told in a webinar it would be interesting that Civil 3D had tools to create surface boundaries.

Currently, corridor surface boundaries are really good but If we create generic surfaces we have to draw manually a boundary.

For example, if we create a surface and we add "Drawing Objects"--·3D faces, we have to erase TIN lines or creating a surface boundary manually.

Thanks.

Aplitop MDT software has a command " find out boundary"

Thank you for your idea. The development team will review the idea while customers continue to add feedback and vote on it.

This can already be accomplished by extracting the Boundary from a surface:

Yes, the surface has to be created first, but that's exactly what's happening behind the scenes of any command that would be solely dedicated to "creating a surface boundary" (a surface has to be created to have a boundary). Also, a corridor has to be created to extract its boundary, so it's the same principle.

Best,

I believe the OP is referring to the fact that when creating a surface from objects, any portion of the intended surface boundary which would look like a "concave" or "indented" area in plan view would be filled by CAD with triangles so as to appear convex. CAD AI could realize the intention of the surveyed area to omit "concave" areas - some points don't need to be triangulated to every other point. In my work as a drone topo surveyor, I deliberately survey only concave boundaries, because it is frustrating to bring data back into CAD and have CAD "fill in the gaps" in the concave areas. With point-cloud type surfaces, the triangulation is especially intense and having to go back and draw a manual boundary or remove the triangles manually is FRUSTRATING! I support this idea.
