Hi Michael ...

I do a lot of architectural stuff ... mostly flat and angled planes and surfaces ... many solid walls and timbers.

Often changes are made during the preliminary design stages.

I am often surprised that solid walls end up as joined surfaces after holes are cut in them (for windows and doors) or when they are trimmed to get walls running up into gables.

I am not entirely sure when or how this happens but I frequently cut a new window into a wall and find that the hole has no surfaces on the walls ends facing the new opening ... just the edges of the outer and inner walls ... I hope this is clear.

How can I get the walls back into solids rather than a bunch of joined surfaces without end caps at the openings?

cheers,
eric
