3D printing

I am struggeling making a small boat model ready for 3D printing. I can’t get rid of naked edges. Is there anyone who could fix my problem, or give me some advice?

Hi Ulf - the What command tells me the object has gigantic edge & vertex tolerances - far larger than the file units, let alone tolerances:
Edge Tolerances: 0.00 to 20.59
median = 0.00 average = 0.07
Vertex Tolerances: 0.00 to 20.61
median = 0.00 average = 0.12

To see what to do, Explode, then RebuildEdges - then see about joining it all up again - you’ll see where things do not join and you can re-trim or whatever.
Did you use JoinEdges in making this model, by the way?

Hi Ulf,
Once i’m done modeling, I export the .stl and open it in Autodesk Netfabb. There’s a simple workflow that fixes all errors.
The best would be to avoid having naked edges checking integrity step by step (in the options, you can apply a different color to naked edges by default in every viewport, so every time there’s an error, you immediately see it).
Hope I could help.
