Push-Pull, in VCP 8 SLT is OVERLY presumptuous and aggressive in its anticipation of what the user is going to select for a push-pull operation.

Hiding everything BUT the involved objects is one way to nix it, but is easy to forget to do, and should not be the user's responsibility to rememeber.

My file is only 464 or so kb, and there are fewer than a dozen solids elegible for push-pull, and all of that is in 4 sets (not groups) spread out across the drawing.

When I click on the Push-Pull tool, when nothing is in view EXCEPT for what will be selected, P/P is blazingly fast, almost instantaneously activating, and as fast in cancellation of the command.

With P/P activated erroneously when lots of geometry is present, it can take forEVER for P/P to present the "do you really wannna abort me" dialog, and even after that, P/P doesn't give any progress indicator of it backing out of the command, how long it will take, or that it is unable to comply with that order.

Multiple times in less than 30 minutes, I've had to abort SLT just to not waste time. Fortunately, in all three or 4 instances, I'd saved my work before clicking on P/P, otherwise I'd have had to choose between losing work or wasting time waiting with no indication of how long I can go do something else while waiting on P/P.

I hope that SLT 9 does not do this. Push-Pull is becoming fun for exploring some new/exciting ideas I have -- except for the undesired behavior I described above

Maybe a way around this lagging behaviour would be to give the option to click within a region to select it, rather than have ViaCAD/Shark try to find all the combinations in real time.
