I am still learning how to work in Sketchup as I go, and I have created a canopy for a new building we designed. Its an odd shape but it was very easy to draw in Sketchup. But now I need to add trim to the top, bottom, sides and corners but I have no clue how to do that. 
so I hope someone in here can tell me what to do. Thanks! (13.6 MB)

It would also help if you can expound a bit more on what you mean by âtrimâ.
Yeah it was about a 5.8mb size drawingâŚoh wellâŚby âtrimâ I mean like door and window trim, ceiling and floor moulding etc. I have a large canopy with metal panels that I need to trim out but have no clue how to create that
That should upload directly to the forum without a problem. Try it again, and allow time for the upload to complete before clicking the button to finish your edit.
