unexisting lines in 3d model

[macgraj 0]

Hi everybody,

im having some problems with my model in Cura.

I have a 3d model in microstation which is solid and there seems to be no problems with the surface etc. but as soon as I export it in Cura the software shows me some unexisting lines in the layer view ( i thought it might be only a problem with a 3d model so I printed it but the lines are still there).

I attach the printscreens of the 3d model in microstation and a printscreen of a model in cura.

Anyone has an idea what is going on?

Thanks in advance for the anwser!

Check the x-ray view. If there are red areas, your model is non manifold (and thus, wrong)
