With extruding sketches, the hard part is if you were to try and revolve, you might have a line offset from your drawing as where you want to rotate, but Alibre wants to extrude that line too. Then it sees that that line has no area, thus no volume, thus an error. Also, to make a tube, you have to do the outside, followed by cutting out the inside.

Oh, and with creating technical drawings, there is some major problems with the dimentions, especially when zooming. I had lines all over my screen and even out of the Alibre window.

The graphics before you try and render with their add on software are like AutoCAD, medicore. You don't expect good graphics from AutoCAD, but you do expect decent stuff from a modeler.

I will say that the company has great support and has a very aggressive releace schedual. If they can keep it up, in a few years, it might be fairly good.
