Dealing with Surface Hide Boundaries when Pasted into Another Surface

When you have a Design Surface that includes Hide Boundaries and you Paste it into a (copy of) your Natural Surface, the area in the Hide Boundary does not display the Natural Surface triangulation. What do I do to fix this?Unfortunately AutoCAD Civil 3D doesn't respect hide boundaries of a pasted surface the way you may expect - in 2009 and earlier versions it simply triangulated across the hide boundary, and in 2010 there is a 'hole' in the surface where the hide boundary was applied. Normally when you paste a design surface on top of an existing surface you want the existing surface to display wherever you don't have your design surface, including in the hide boundaries of the design surface. The answer, in short, is to create a copy of the existing surface, apply the hide boundary as an outer boundary, and then paste this on top of the merged surface. Essentially this takes a chunk of the existing surface and slams it in the hole. Starting with three surfaces; Natural Surface, Design Surface and Merged Surface (this is the paste of Design Surface on top of Natural Surface, the steps to infill a hole is: The Merged Surface should now accurately describe the natural surface levels in the hole of the design surface. Repeat this process for each hole. Version: Civil 3D 2010, 09, 08, 07 ,06 | |
