Hello,
I am new to Power Geopak V8i SS2.
I want to add an "internal boundary" like a hole or void area in a tin surface without adding vertices to the tin data. It looks like the proper way to accomplish this, without adding vertices to the surface, is to add a polygon graphic by selecting the Extract Graphics command in the DTM Tools under civil workflows task. But there is also an options to drape linework or "Polygon Move Z" in the Edit Triangles command in the DTM Tools which seems like would accomplish the same but would add vertices to tin. I have not been successful yet to get the void to appear in the surface by the first method, but want to ask what the preferred workflow is for creating an "internal boundary" in Geopak?
