Below you see the Front Apron component, and to shape those ellipse and rectangular patterns of crotch veneer, I need full-size templates in the shop. Because of the serpentine shape of the Front Apron, these ellipse and rectangular patterns (the ellipse is shown selected) are curved. I need these curved faces flattened so that the full size template can be placed on the curved surface of the Apron and provide an accurate full-length shape.
With SketchUp, you will get the easiest and the best option to unwrap any design of your choice. The Unwrap and Flatten faces Extension is solely designed to provide you with innumerable options to do your job as an expert designer. While the basic steps remain same for both digital users and practical experts, other methods are completely different from each other. You need to unfold the shapes and keep them flat for cutting. The tool for the SketchUp user sometimes unfolds shapes automatically. The content discusses how to unwrap complex objects on SketchUp.
Unfolding for developable shapes is not an easy task as designers need to deal with the completed surfaces to flat the shape first. In a knowing term, objects with flat surfaces give you the freedom to unfold the design. The double-curved objects are hard to unwrap in SketchUp, and this case, a special attention must be taken. The designing suggestion tells you that always choose the part of complex objects which cannot be unfolded in a regular way. Separate that part from the rest and unfold it in a general way.
There is still a need for 3d > 2d unfolding to create flat patterns. I have tried to create a low polygon model in Fusion 360, export it as .obj, import it into Mesh Mixer, and "unwrap" to create patterns. The workflow and results are a nightmare! The Mesh Mixer UI is clunky -- I would much prefer to remain within the Fusion 360 workspace where I can easily view, move, and transform objects. I realize that unfolding high-polygon objects or flexible materials such as steel have numerous issues. This is not what I am talking about. What I want is the ability to translate a low polygon model with well-defined, flat, rigid faces into a perfectly flat pattern with negligible material dimension (i.e., paper) - like a .pdf or .dxf file that contains two things only: cut lines and fold lines. I don't necessarily care about the location of the cut lines (versus fold lines), although it would be great to be able to specify my cut lines using the "crease" tool in Fusion 360.
