uroutoftime 0 Posted March 29, 2017 in Top of Object Red in Object View (edited) Hello, so I designed a spinner in blender and exported it, and when viewing it in cura the top of the object is red, and I was curious as to if this should be cause for alarm before sending it to my schools 3d printer. I have made a few other spinners the same way in blender and they didn't have the red top. Solid View Any incite would be helpful. Thanks!

DidierKlein 635 Posted March 30, 2017 in Top of Object Red in Object View That's weird, normally it identifies the overhangs. Should not be a problem in that case Share this post Link to post Share on other sites
ahoeben 420 Posted March 30, 2017 in Top of Object Red in Object View (edited) The modeler you used uses a different "winding order" for normals. So the part of Cura that visualises overhang actually thinks your model is inside-out, which makes causes overhang to be shown on top surfaces instead of bottom surfaces. http://cmichel.io/understanding-front-faces-winding-order-and-normals/ CuraEngine (the part of Cura that does the slicing) does not use the normals of the geometry, so it is no problem for printing.
