You just click the surface you want to flip and all of the triangles attached to that surface will be reversed. Typically all connected triangles are facing the same direction and this option will help correct those issues.įlip Surface Orientation – Using the Repair Flipped Triangles tool is great, but you may run across a scenario where all of your triangles are pointing the same direction, but it is the wrong direction! In this case, you can use the flip surface orientation option. Repair Flipped Triangles – The software will analyze your model and look for any surfaces where a triangle appears to be facing the wrong direction. Repair Normals – This will recalculate the normal vectors for your model to help prevent issues where the normal is facing the incorrect direction That way you're only printing the outer perimeter, not the outer and inner.įor the rest of the repair features, I would advise for looking at the tutorial on the tutorials page for Repair features.Īlso, one last thing is to use the Identify Non-Manifold Edges option, which will highlight in red problematic areas that show where the mesh is either not 'water-tight' or has extra/unwanted surface faces that are causing conflict. In addition, Merge all outlines into a single solid model is good for thin-wall printing if you'd like to ensure that one perimeter outline is printed. For instance, if you had a model that was a block with screw-holes in it, but had 'Merge all outlines into a single solid model' on, the holes would not show up. This feature in the software will slice the model taking all of the outer most perimeter outlines. Merge all outlines into a single solid model (Advanced Tab FFF Settings) - I've talked about this feature for the Vase mode tip of the day, but for other parts it can be useful as well. All-in-all this is a very easy fix and many models I've downloaded off of Thingiverse have required this simple one-click fix.
