Missing sections in layers view mode

[the-noble-robot 0]

I've been getting this problem using Cura 14.01 with a number of STL files lately (image attached). This happens with models both of my own design and ones downloaded pre-made by others. I assume there are errors in the mesh, and perhaps this is a common problem, but I have no idea where to begin in fixing them (I'm using Blender primarily). I'm still new at this, but I haven't seen this problem until recently.

Any idea?

looks like an stl file problem but if you change your extruder diam (just as a test,input a smaller one... change it back later) does it then display the missing layers when sliced?

This model is so messed up it could take days to fix it. It appears to be filled with holes and hidden inner parts.

I guess I would try the 4 "fix horrible" checkboxes. That will only take you 20 minutes to try all 11 combinations (don't check A and B at the same time ever). They are in the expert settings. Set the layer thickness very thick to save you time when experimenting with which setting helps the slices.
