Using Union operation on Wall shapes - unwanted extra shapes

[RogerC]

I'm creating floorplans in Visio, saving them as AutoCAD .dwg files and
importing those into SketchUp to turn them into 3D drawings. I need to
prepare the Visio drawing so that my Wall segments are all combined into a
single shape . (This makes it easy to create Faces from them after I take
them into SketchUp). If I keep them as individual Wall shapes, in SketchUp I
have to create an individual Face for every Wall segment, and I get small
lines at the corners where the Walls meet. Whereas, if I simply combine them
as a single shape while still in Visio, I only need to create one Face in
SketchUp and I don't get the extra lines.

I use the Union operation to make them into one shape which works fine,
except; a small triangle is mysteriously created next to every Wall section
in the group I'm combining. So, for a square four-Walled room, I end up with
four triangles I need to remove. They're somehow connected to the Wall shape
itself so the only way to remove them is to click on every vector point on
each triangle and delete the points from the master shape unitl they are
gone. It's a pain.

Can anyone tell me how to use Union or Combine and not get these triangles?

The triangles are the result of selecting a wall. They're part of the
temporary dimension for the wall. Haven't figured out how to turn them off.
You can try the following, however. Instead of combine do a group first, and
then combine. You'll lose the fill color, but that's very easily added back
in. The grouping eliminates the individual wall selections and drops the
triangle.

Thanks WapperDude! That's a better approach.
