Surface Hide Boundaries

I am trying to create a composite surface of existing and proposed.  I have extracted a boundary from the proposed surfaces, but when I try to create a hide boundary on a copy of the existing (non destructive breakline checked) it doesn't quite work.  The triangles have altered along boundary but the ones within the boundary haven't hidden.

 

Have any of you had this problem?

 

Thanks in anticipation

Have you tried pasting the proposed into the existing? (Surface edit)  That would be the typical way to create a composite.

 

The only time I use boundaries is when I am trying to meld two disimilar surfaces.  For example a surveyed surface and a GIS surface.  The way we would typically do it is to offset the boundary outward a distance (depends on how different they are) and then let the triangulation smooth the difference.

 

Hope that helps,

Whan you add a Hiddden boundary there is an 'S' option at the command line to use a surface as a hidden boundary. Did you try this? You may note even need to paste EG & FG together.

Actually, I would suggest NOT pasting into the existing surface.  Create a new surface, paste the existing into it and then paste the proposed in.  This will leave the existing in tact.  See the screen shot for the location of "Paste Surface" (it's disabled in the screenshot because I only have one surface in my current file).

Thanks cwitzel, I think I was trying to make this more complicated than I need to.

Thanks doni49, this worked, my method was too complicated.
