![]() Joko Engineering generally does targeted tutorials and stays on target to keep the session short. I went from a bunch of years using OpenSCAD to less than a year on F360 so it was an easy jump to FreeCAD since I only had concepts to shift, not any muscle memory or implementation patterns to unlearn/shift. ![]() Ya, with that many years on the other packages and especially AutoDesk products FreeCAD is going to take some getting used to. I’ve watched a few of the Mango Jelly tutorials before but I find he strays off the point and goes way too slow for me to retain interest. Before long, you’ll even wonder why people even mention F360 let alone have to deal with either the annual licensing or constantly having to upgrade just to share a design made a week earlier with the then latest version. Keep at it and remember, what really will make your CAD experience enjoyable is spending time doing it and checking out the tutorials.

Once AutoDesk, the owner of F360, started playing games with changing their licensing AND I found out they were making the file format completely incompatible with later versions, at the sub-version level(ex 29.02 wouldn’t be compatible with 29.03 ) I jumped to FreeCAD. F360 had a bunch of bugs which surprised me and I got responses like, oh yea, if you do it this way you don’t get that error. Well done and one thing I learned when I first started learning CAD with F360 was that there are often a number of ways to start a design and the starting process often determines how the rest of it goes. I’m sure that other 3d CAD programs can be used instead of FreeCad in this technique. svg file”, and that file may be imported directly into LightBurn. (3) FreeCad can export the cross-section as a “flattened. The result is basically a cut line for the sewing pattern. (2) The FreeCad Part Workbench has an “Intersection” tool that, by default, makes a cross-sectional cut at Z = 5 mm for my body. It’s beyond the scope of this note give all the gory details, but I ended up with a 3d shape that looked like the pattern I wanted in the top view of the shape. I used this capability to design the pattern “3d body” with X and Y parameters referenced to the spreadsheet, and all Z values set to 10mm. Dimensions and locations for the primatives may be saved in the cells of an internal spreadsheet, with meaningful cell labels assigned. It’s very similar to what LightBurn can do with its 2d shapes. (1) The Part Workbench in FreeCad has various shape “primitives” (rectangular cubes, cylinders, letter shapes, etc.), that are used to create complex shapes, using boolean operations. svg file that LightBurn could directly import for cutting the pattern: So I used the following steps to design the pattern parametrically in FreeCad, and then export it as a. ![]() I use FreeCad for my 3d printer design work, and it is a full parametric design tool, meaning that I could enter the dimensions of, say, a new phone, and the pattern would automatically adjust to its size. LightBurn would be used to cut out the leather pattern for sewing, and I wanted to make the pattern automatically adjust, based on the size of the phone. I was working on a leather sewing project to make a belt holder for my iPhone.
