Extrusion overflows to neighbouring area.

[Jaeger1787]

I am trying to extrude the framing shown here:

As far as I can see, it appears to be fully defined.  If I hover the mouse over the frame it turns blue, likewise if I hover it over any of the triangular areas they turn blue.

 

When I try to extrude the frame, I get the upper right quadrant filled in as well.

I can not find any apparent leaks of the frame, particularly around this area.  The error message simply says 'compute failed'. All the corners of this triangle indicate co-incident restraints.

Why is this overspill occurring?  File is attached.

strange, it seems to work for me.  Am I doing something different?

Thanks Jeff. Following your message, I found the source of the problem. Extrude No. 7, further down the time line had an error in the profile selection. Now corrected. (I blame a manic mouse.) I had attempted to amend the design, and somehow had inserted the erroneous inclusion when creating the bolt heads on the diagonal strut.

What I need to do now is to copy these to the other strut........

Thanks again.

Keith.
