I downloaded sketchup Pro to try it out. It is my first time working on 3d objects. I have a 12’ ladder that is a component I imported. I would like to trim or chop 8’ of it. I drew a 8’ solid block (group it) and lay it across the 12" ladder. I tried to intersect but a popup came out and says:
“One or more of the selected object is either not a solid or is locked. The non-solid/locked obj. will be desected before this operation is performed”
And the ladder was de-selected. I guess how do i make the componenet as solid?
