I'm working on a part which was imported from Pro/E. It's a jumbled mess of imported solids and surfaces all in one part. When I try to section it, so I can see inside, I get the message:
"Sectioning at this position will produce invalid bodies. Please select a different section position."
Offsetting the sectoin plane doesn't help, and neither does trimming manually. I can cut the solid bodies away, but when I try to trim or split the surface bodies, I get a message saying:
"Unable to trim due to error in target body"
Note there are no rebuild errors on this body (all bodies with errors are suppressed).
Is there any way areound this?
Thanks

I have seen this before, but it's been a while. Found this in the KB - Solution Id: S-019130
The section plane used may be producing the invalid bodies; bodies with a 'zero-length' geometry condition. This is not supported by SolidWorks. A workaround for this is offsetting the section plane by a minute value (say, .01mm) and then doing the sectioning.
One example of this problem can be when the section plane is tangential to the surface of a hole. See some other illustrations of this problem in the help documentation topic 'zero-length geometry'.
