![]() Yesterday I managed to create the bulb cap using FreeCAD after few hours of trial and errors. The UI is outdated, building a model requires many steps, tiny size of user community and tutorial demands tough and long learning curve. I spent two days on BRL-CAD and removed it. I think CSG (Constructive Solid Geometry) is superior method over Mesh modeling. I’ll use Blender for organic or artistic model. I was able to create an organic model within few hours.īlender can be used to create a mechanical part that requires exact dimension and shapes but it’s tedious process. I quickly went through 2,000 pages of Blender Noobs to Pro, got familiar with Mesh modeling technique. Since then I’ve been testing various 3D modeling software: Blender, BRL-CAD, OpenJSCAD, FreeCAD. OpenSCAD have not supported multithread or GPU yet. I5 system renders the model about two and half hours. So I tried it on brand new Devuan workstation I built. I thought spending half day of work just to create a simple model is bad for the 3D studio business I gonna run soon. The rendering of OpenSCAD takes about three and half hours in my Devuan Linux, AMD FX-6100 processor, 8 Giga memory. I started experiencing limitation of OpenSCAD few months ago while I was modeling a hollow shell that has many holes. I used FreeCAD 0.16 following the video tutorial. This was the first FreeCAD 3D model I printed.
