Hi, i am using the Solid Edge ST8 academic version and get a error while trying to extrude.
The error is: extrudedprotusion with a yellow triangle. Tried reinstalling the program with no luck.
I think this is more or less a logical problem with YOur choosen geometry or with the length value of Your protrusion.
But without any picture or movie it will be hard to get the right idea what reall might be the problem.
a.f.a.i.k. academic activation won't have an MP.
As @hawcad has mentioned the yellow triangle, especially with an extrusion, has more to do with the selected geometry and the extrusion extent and post extrusion geometry condition.
A picture or video will help fix your issue faster.
