Hi,

I've not seen that message before. Maybe it's because the radius of the arc is smaller than the size of the region to be extruded. What I mean is, will the region insect itself at the base of the arc as it's extruded?
If so, I don't think AutoCAD likes it and creates an error. Just make sure that the arc is large enough for the job..

If it's not the case, I'm not sure what could be causing the error?!!
