So i would like to suggest to switch on Face Orientation at least once before giving up on surface problems, most likely if it turns out to be the Normals, the solution is underestimated easy.īe it with recalculating Shift+ N to let Blender figure out what's in- and outside, or by selecting the wrong ones manually and flipping them with Alt+ N selecting "Flip". While it is easier to spot with the Face Orientation it does not replace the Normals as those i compared were only the Face-Normals.īut something that happens often is that we work on geometry and apply subdivision surface modifiers to name one that makes most obvious problems with wrong Normals, just to then have to find out that a face got turned for whatever reason. I seem to need a way to identify the faces created with the pushpull and reverse each one. Front and back of the face become blue and red respectively to have a strong contrast and allow better visual identification. I have tried that and to make sure I tried again still reversed. Here i would suggest the Face Orientation to help get an easier overview on where there are faces in the wrong direction. Click and Click and Drag mode to reverse or orient progressively face by face, or surface by surface and to extend a surface already painted Explicit selections of faces: single face, surfaces, connected faces, adjacent faces with same materials. There is a useful plugin called Makefaces.rb that facilitates the users to produce a face or multiple faces out of existing linework. The tutorial briefly shows how to use Sketchup Pro 2016 to generate faces and resolve all the crucial issues associated with faces. Normals (or the orientation of the faces) in Blender can be made visible in 2 ways, one way would be with little lines pointing outward from the middle of a face, specifically the face-normals, while it gives us the information we may need, it can be hard to see wrong directed normals on complex geometry and long stretched faces, if you are a bit zoomed out. You don’t need to open groups and components to paint their faces or edges. This sketchup tutorial is made in spanish language. Once you have your shapes drawn or your model imported, use the selector tool to select all of the shapes. While the question is rather old and solved, it's still an important and underestimated topic leading to other questions coming up, so i would like to add one approach i did not see in the available answers here, for completeness sake. Normally you right click on a (sur)face and select ‘Reverse’ in the context menu. First, import your 2D AutoCAD model, or draw a few shapes in Sketchup.
