I am quite new to blender and I need some help to “thicken” a model that I designed in SketchUp!. I imported the model properly into Blender but have been unable to add some heft to the lines. I tried to use the “mesh -> scripts -> solidify selection” script but that didn’t seem to do much of anything. Any help would be appreciated. I would like to add around a 1cm thickness (inward, the model is already the correct size on the outside) to it.
I have attached my .blend file. Thanks in advance for your help.
