Solid Tools stay greyed out

Rob Figee

Hi, I created two solids by push pulling a square. Selected them and turned each into a group. Object properties says they are solids. I moved one a bit into the other to subtract them, but the solid tools ( except for the first one) stay grey.
What am I doing wrong?
Thanks in advance for your reply,

I assume you have SU free.. solid tools are a pro feature. (except outer shell)

Thanks, that explains it.

Here is a quite inexpensive alternative: http://www.smustard.com/script/BoolTools
And here is a free alternative (although I know that "strictly physically speaking" you cannot alternate between three things but only two): http://forums.sketchucation.com/viewtopic.php?t=14773

This latter says "for SU 8" so either upgrade to SU 8 or upgrade your forum profile: http://forums.sketchucation.com/ucp.php?i=profile&mode=profile_info
