part orientation - crummy rotation tools in XYZware

Sent this to XYZ customer support, waiting to hear back or maybe others here have found a solution?

Hello XYZ,

I really enjoy using your product and amazed at it's price/capabilities.  Well done! 

I'm having an issue when I import an STL originally created in Solidworks. 

Sometimes the part doesn't import into XYZware in the orientation that I want to print it.  If I use the rotation rotary wheels in XYZware, I can get it to look like it's oriented correctly for printing, but when I do print it, the print comes out very slightly tilted.

If I'm printing a cylinder for instance, when creating the first layer, it won't trace the complete circle, but instead starts at one side and creates a crescent shape, on subsequent layers, the crescent gets bigger and bigger until eventually the circle is complete... so it seams that while the cylinder looks straight up and down, within the software, it's actually slightly tilted and only one spot on the outside edge is touching on the bed. 

I think the problem is with the rotation tool.   The smallest increment it displays to the user is a single degree but the software seems to actually rotate by smaller increments than one degree .    So getting an exact angle of rotation is nearly impossible.  I'd suggest allowing direct numerical input to fix this.  And this change would allow me to avoid the process of trying to rotate a .75in diameter wheel to an exact angle with my mouse - feel like using a sledge hammer to drive in a push pin.

I can go back into SW and reorient the part, then re-export, but this is not always easy and can cause other complications.
