Cura fills up holes, that should be empty

[sipo19 0]

Hello everybody

I`m in 3d printing for only about month and had a few problems earlier, that i managed to fix by my self, but this time I gave up.

In many models, already had this problem, but small remake usually fixes it. But this time I can`t make it to leave it empty, Cura just fills up all the model. I`ll be thankful for any suggestions that could help me fix this.

Did you create this model?  Is it from sketchup?  Sketchup specifies which sides of every surface is the "outside" or "inside" by the color.  White goes outside.  Gray goes inside.  Most people using sketchup ignore this but it confuses cura and ends up filling interrior spaces like this.  More info here:

You show the model in 2 views (layer and solid), please check the model in the 3rd way: xray view.  If you see any red in xray view then that's the problem right there - it means you have extra walls or missing walls (the part is not manifold/solid).
