Cura is complaining that my models are not watertight and that the “normals” are not correct.
I have installed the Cura Plugin/Extension “Mesh Tools” and it is successfully fixing the normals and most of the “holes”.
However, my models don’t have “holes”. I am meticulous in their creation and most things are square, so there should not be any holes…although Cure Mesh Tools claims there are.
And, what are “normals” and why is Cura complaining about them, and why is Sketchup having this problem with “normals”?
Yes, again, I am meticulous that every edge matches up and connects perfectly, and I frequently will rebuild a section if there seems to be anything odd. So I am pretty convinced this is a Sketchup+Cura problem and not [likely] a problem with the model itself.
My 3D prints are correct when I use Mesh Tools to fix them and they often have problems without using Mesh Tools.
Is there an answer for this?
