Realthunder has been working with the main team to get his toponaming fix into mainline FreeCAD, and they’ve already adopted several of his UI improvements and settled on an assembly workbench. Version 1.0 should finally be released by the end of the year, and the weekly builds are promising. I don’t know if it’s quite there for me yet, but I’m hoping it will be by the time my paid-for Alibre is feeling long in the tooth, and any CAD DIY enthusiast would be wise to keep half an eye on FreeCAD.
