The new PartDesign work flow in 0.17 will alleviate this issue because mapping sketches will no longer be a prerequisite to use subtractive features, and new datum planes will also help in that regard. If a sketch was mapped to Face2 and after a change upstream in the tree, the face ID gets changed, the Sketch won’t know the new ID and will be remapped to the new Face2. Basically, due to the OCC kernel, topology elements (edges, faces) are given arbitrary IDs (Edge1, Edge2, Face1, Face2, etc.) which can change when the model is edited. This is caused by what the developers have named the topological naming issue. It seems that you never asked for pointers about it… I’ve never been able to fix a design once it breaks. I chose 7, because I wanted 6-sided polyholes to import as hexagons but you can reduce this value to get circles.īut FreeCAD, if anything goes wrong, I found I had to scrap the design and start over. For any Openscad “polyhole” with a higher number of sides than this number, a true cylindrical surface will be created. Set the “Maximum number of faces for polygons”.Under OpenSCAD import, check both “Use ViewProvider in Tree View” and “Use Multmatrix Feature”.Under General OpenSCAD Settings, specify the executable path by clicking on the button at the end of the field to browse your computer. Switch to the OpenSCAD workbench from the menu View -> workbench. Then you need to configure the OpenSCAD executable path.

First you need to install OpenSCAD on your computer.You’re of course welcome to try, but you may be disappointed.

Of course this assumes you’ve already downloaded and installed FreeCAD! FreeCAD works well on Windows and Linux (can be installed easily on Ubuntu), but the Mac version is less up-to-date and suffers from Mac-specific bugs, and for this reason I cannot recommend it on this OS at this time.

How to configure FreeCAD to import OpenSCAD parts I don’t like CSG work flow as I find it too primitive and a hassle to edit, but it beats the hell out of trying to figure out OpenSCAD syntax, or modeling the part from scratch using the STL as reference (which I had been doing until now).įor example here’s the AO-101 x-end-idle_ACME.scad file in OpenSCAD: scad source files and generates a CSG tree.
Well I tackled it in the past week and found out you can get surprisingly good results. As a CAD user with more than 15 years of experience working with a few 2D and 3D CAD packages (among them the ubiquitous AutoCAD and parametric programs such as Autodesk Mechanical Desktop, Solid Edge and SolidWorks), I find it extremely hard to understand how anyone can design by programming lines of code, even less how can anyone analyze and modify OpenSCAD parts made by others.Ī couple of guys have worked on an OpenSCAD module for FreeCAD and it was first included in the /1830 stable version which came out last February. I’m guessing I am not the only one who simply won’t put any energy into trying to learn OpenSCAD.
