Not sure if anyone else is having this problem. I was playing around today with Zmodeler and thought I wanted to do a Spin on some polys like Joseph showed in the Sneak Peak Video, but its not using the Target correctly. Have it setup for Polygroup All but it only performs it on a single poly no matter what I do, I’ve masked it, changed polygroups with no success. Anyone know what I’m doing wrong.
I’m having this same issue and was going to report it after going through some more videos and tutorials.
I’m glad Im not the only one
I too am having this issue. I saw Pixolator do it for the doors on the dumptruck video and could not replicate using spin. Running 64bit, Win 7
I’ve also that problem. But there exist an second between solution:
Set all the inner-polygroup-surfaces with the Alt-Key to a temporary (gray) polygroup. And then try again to spin all that inner-polygons. 
To make Alt-Key temporary-(gray) polygroup, choose: QMesh > single poly.
And after that temporary polygroup set, change again to Spin > Polygroup All. And spin then your polys.
PS. Pixo works on a patch 2 for Windows and Mac. Check:

Read the last words (Note:).
A couple workarounds.
In the OP’s case where he wants to spin a bunch of inset polygons around a radial surface, turn on radial symmetry with a count equal to the number of targets. I haven’t seen the video in question, but it’s possible this was how this was done in the original case. The vids feature the use of radial symmetry with ZMod elsewhere.
In a case where you want to rotate a cluster of polygons on a plane all at once (like an entire polygroup island), use the Transpose action instead.
Transpose doesn’t rotate each individual polygon the way the spin function does. The temporary polygroup (gray) solution works.
Ah, I got confused, I thought spin wasnt working on polygroup islands, but it is. Thats all I meant.
Radial symmetry works for the OPs case, though.
Thanks for the Workaround. Hopefully the Patch will fix that. Watching Josephs Video he didnt use Radial Symmetry, but it was probably the Alpha version of the Software, and we all know that if they fix one problem it sometimes breaks another Tool. So many functions in this one tool, I’m surprised there’s not too many other bugs in it. Well Done Pixologic
