My 13 yr old son is designing and building a 16’ utility trailer for his Ag Mechanics project (with guidance from his dad). We have SketchUp Pro 2019 and he’s learned what he knows from online tutorials on his own. He has already drawn the frame and tongue of his trailer and is ready to add parts like springs, axles, coupler, etc. We have found some components in 3D Warehouse, but they are not the right sizes/designs. How should he draw or get those shapes to add to his design?
He loves using/learning SketchUp, but is frustrated at this point and I want to help him find some answers. Please let me know if I need to ask this in a different area of the forums. Thank you for any help you can give!
