I have made a bunch of different door styles on sketchup and want to be able to stretch them to be different sizes. I am sort of new to the program, I have mainly worked off Autocad. I was wondering if there is a way to make a dynamic block which stretches the design properly. When I stretch, it does not stretch properly. Eg. I have a 8cm border and when I stretch it the top and bottom stays 8cm but the sides stretch out to be more then 8cm. (I hope this makes sense). Any help will be greatly appreciated.
Ps: I have looked at tutorials and also used the scale command. No luck.
