@gaieus said: Hi dmr, I'm a PC user so I'm not sure but it seems that if you double click on a material in the browser, you should be able to edit it - including its width/height. See the user guide for details: http://download.sketchup.com/OnlineDoc/gsu6_mac/Content/F-Model_Settings_and_Managers/Settings-ColorPicker-MAC.htm (scroll down to almost the bottom). Thanks for the link Gaieus. When I get home from work I will give this a try. I swear I have tried this before but it wouldn't surprise me if I missed it . Thanks again
