Slicing behaves differently at different scales?

Recommended Posts

Posted · Slicing behaves differently at different scales?

I have a model (attached) which I import.  I look at the Layer view and it looks OK; I scale up the model and now the Layer view indicates most of the model won't be printed (as shown in attached screen shots (scaled version at left, unscaled at right)).  I have done my best to clean up the model, but would there be any type of model feature that breaks when surfaces get farther apart or something?

Using Cura 3.2.1 under OS X 10.13.4.

Playing around further it seems this only happens when I put the model over on its side like that; if I retain it in the original rotation, the slicing seems to work as intended.

Sketchup yes, though not my work.  I suspected the model might be fishy so I tried to clean it up with meshlab.  After I put that file up in my original post, I specifically did a Re-orient all faces coherently, but this did not seem to make any diffference, so now I put it through Netfabb and this seems to have fixed the problem.  I’ll see if I can print it :-)

 

Thank you!
