You don't have to replace all the vertices, you only replace as many as you need to use the Subdivision surface modifier. Retopologizing roughly means you sit down and redraw the sculpted shape vertex by vertex, but with a focus on clean topology and as a single object. In Blender, these issues can be mitigated with two things: Retopologizing and the Subdivision surface modifier. What makes this even worse is that sometimes, it makes sense to build bigger models out of multiple objects, rather than just a single one. Especially after sculpting, the topology of the mesh is generally sub-optimal, not to mention so dense that an Stl imported into FreeCAD is extremely hard to handle. It is almost entirely mesh based and its NURBS support is very basic. However, Blender isn't the greatest at creating objects that can be used to create toolpaths. For me, who is more on the art/design side of the 3D-modeling spectrum, this is something I often miss in FreeCAD, which is why I turn to Blender for these operations. Overall, Blender gives you far more freedom when shaping objects and you don't have to "think ahead" as much as you have to with with a regulat CAD program. The extreme in this case surely is sculpting, where you can basically shape the object like it's a virtual block of clay. While FreeCAD is very technical, Blender is much more free-form. I know that FreeCAD isn't the right program to do this, so they are being built in Blender, by sculpting, retopologizing and using the Subdivision surface modifier.įor those unfamiliar with Blender, here's a little description of what I'm talking about: I moslty need it to design CNC paths, but sometimes, the shapes I want to create can become very organic. I'm using FreeCAD mostly in a not exactly technical way. This is really more an attempt to discuss workflows, whether what I'm trying to do here makes any sense and so on.Įdit: Tl, dr: I want to import a low poly mesh and use its vertices to create a NURBS shape from it. I'm not super sure whether this is the right spot for it or whether this should rather go in the open discussion section, since I'm not sure whether there is a way to actually do what I'm looking for.
