All solid tools command disappear

I do not know what happened but all the solid tools command disappear on rhino. Whenever I type a function belong to solid tools it reports unknown command. Anyone knows how to fix this without reinstall the whole rhino. I have tried restore toolbar.

Solid tools are in a plug-in that is installed with Rhino. Check in Options > Plug-ins and see if it’s loaded and active, if not, check the “load” box and try restarting.

This is from memory, hope the details are correct.


yeah it worked thank you
