Hello, I am trying to use the rectangle tool in Layout to then create a clipping mask for room elevations, but the ‘create clipping mask’ option under the edit tab doesn’t show to be clickable. Does anyone know why this might be? Thank you in advance for your help! : )
See the Help article
You need to select the rectangle and the viewport you want to clip before right clicking.
Did you select both the rectangle and the SketchUp viewport? When you do that, Create Clipping Mask should be both in the Edit menu and the right-click contextual menu.
