Fiat Ducato Sketchup Today

I currently have the whole body as one group. Should I explode it and make the left/right/front/roof individual components to mirror details? Or will that break the watertight mesh for 3D printing?

![Image 1: Wireframe front bumper] ![Image 2: Layout with bed and kitchen] 1. The Cab Roof transition. The Ducato has a subtle "drop" over the driver's head.

Building a digital Fiat Ducato van for a conversion layout. Stuck on the curved windshield and roof lofting. Help a builder out! Replies you might get: @CAD_Shaman : Drop the Follow Me. Use Curviloft for the roof. Draw 4 cross-section lines and let the plugin create the surface. Set "Loft type" to "Skin" – no pinching. I currently have the whole body as one group
