Thanks for the reply.
The problem I am facing now is that all the actions involving the curves or complex plugins cause my sketchup to stop responding (not crash-sorry for misusing the term earlier).
My office computer, windows version, seems to work perfectly fine when i perform the similar actions. They usually take just seconds to complete, but on my macbook, the longest I waited was about 2 hours and it still wasn't responding.
I have tried simple geometry just to get the plugin to work. Like trying to get a rectangle to bend along an arc in shape bender. No shadows or materials, working on a new file. It always get stuck at "finalizing all bends".
Would a reinstall of my sketchup help? Everything else works fine though. Just the mentioned problems with the plugins.
