We are a production home builder using Softplan 2020 to create all our construction documents. We are very skilled at using Softplan to create 2d construction drawings. However, we aren't as skilled using the 3D aspects of Softplan.
We are trying to 3D print models of our 12 base floorplans. Our workflow for 3D printing is Softplan 2020 -> Sketchup Pro -> STL file for 3D printing.
The problem is when we export a design to Sketchup it is not manifold (watertight). I've attached a picture showing one example. Instead of solid walls that can be printed, the Sketchup export has hollow walls that are 1/2" drywall on interior, and 1/2 drywall and 1/2 siding on the exterior. We are printing at a 1" = 10' scale (1:120), so the walls become .004" thick, which is too thin to 3D print.
Obviously, we could spend hours to manipulate the walls in Sketchup to make them solid, but there has to be a setting in Softplan that creates solid walls.
Is anyone else 3D printing designs from Softplan? If so, would you mind listing your workflow steps?
Thanks in advance,
