That kind of optimization will still require intervention. But the path job won't make more efficient use of material if you cut two small doors instead of one big one. That way you could just adjust the parameters of the model and then post-process the job again. Maybe you want parametric models as described above, but you want them linked to a stable Path Job. It would be especially useful to link your parameters into a spreadsheet. Rather, you need to design the models right in the first place so they are parametric and stable.
Maybe you want to have parametric models of doors and cabinets that you can adjust and which can be used as the base objects for FreeCAD Path Jobs. So I assume you mean you want to parametrically generate regular gcode. I don't think that's what you want and FreeCAD isn't well suited to doing it anyway. Going off of your title, there's a lot of different ways to interpret what you're asking for.įor example do you want to generate gcode which is parametric? Simple Gcode routines can be written to use variables rather than hard coded values. LinuxCNC has a tool to do something like this but it's really just using the greyscale of the image to control Z depth. He has seen many makers get lost in their first encounters with FreeCAD and is now doing his best help them navigate through it.Generating gcode directly from an image really isn't possible. He has used FreeCAD to design everything from salt and pepper shakers to Mancala boards, tool organizers, and giant mechanical clocks. He runs Vector Space, a makerspace in Lynchburg, Virginia, where making is plentiful and FreeCAD reigns supreme.

Skill Level:There is no prior experience necessary. The result can be a DXF file ready for laser cutting or an STL file ready for 3D printing. This means we’ll measure real world components, then work through the process of drawing them precisely in two and three dimensions. In this course, we’ll draw household items as we learn the basics of FreeCAD. This is the role of CAD software, and FreeCAD is the pinnacle in the free and open source world. Whether you hope to make something on the 3D printer, laser cutter, CNC router, or any other computer controlled tool, knowing how to draw precisely dimensioned parts is a critical skill.
