I use SketchUp for small models and then print in 3D.
To troubleshoot intersected in small dimensions (< 1mm), I tried to scale the largest and then reduce it to the end model (as they say on the forums) . But the problem remains the same. Because large-scale functions do well, but then there are problems to reduce error, SketchUp manages your way. Sometimes leaves gaps and I can not print.
Hi,
Because of this problem with small dimensions I’m only work with meter units,never with mm.
So I start to design like 1m is 1mm, or import model in meter scale and when the model is ready for 3d printing I just export to STL in meter units.The STL file doesn’t have the units information so is the same file in mm or m.So I never need to scale the model.
