Hi All,

This is my first post in the forum so apologies if I miss a convention.

I have a relatively detailed sketch (tree of life) which I am trying to extrude to form a grill plate on the front of a stereo.

When I try to extrude the sketch I get an error message: "Unable to create this extruded feature due to geometric conditions". The sketch seems to be defined and I can not see any open contours.

Has anyone got an idea of what is going on?

The file is also attached.

Thanks in advance.

Billy
