Get Blender For Dummies®, 2nd Edition now with O’Reilly online learning. Remember that you're basically trying to flatten a 3D surface to a 2D plane. Blender has very powerful unwrapping tools, but to take full advantage of them, you need to first define some seams. However, despite the menu's variety of options, unless your mesh is simple or a special case, you should use the first menu item, Unwrap. You then see a menu with a handful of options. You unwrap a mesh in Blender by selecting all vertices (A) and, while in Edit mode (Tab), either pressing U or choosing UV Mapping Unwrap in the Tool Shelf. In essence, the world map is an unwrapped texture on the globe, whereas the latitude and longitude lines are the UVs. The map of the world uses the latitude and longitude lines to relate a point on the three-dimensional surface of the globe to the two-dimensional surface of the map. To understand this process, think about a globe and a map of the world. However, Blender is predominantly a mesh editor, and in order to get proper UV coordinates on your mesh objects, you must put those meshes through a process known as unwrapping.
With NURBS surfaces, you get UV coordinates for free as part of their structure. UV mapping also allows you to take advantage of other Blender features, such as Texture Paint mode and texture baking. 7&start=10, but I can not find it in the Mesh Design workbench.The most precise type of mapping you can use is UV mapping. I am searching for a way to use the unwrap surface function, as shown in. Currently other projects are more important. Maybe one day I have some time to work on this again. It's included in the FreeCAD-source, but there are only two cammands in mesh-part menu to unwrap meshes and surfaces. Great developpement! Any news about this surface flattening algorythm? Maybe some macro exist? That would be great
