After years, we’re still revisiting a new #GSoC proposal to implement #NURBS functions in #Blender, another ambitious project. I’m skeptical: wouldn’t it be better to leverage existing tools like FreeCAD’s #OCCT kernel and wrappers such as PythonOCC, which already provide ready-to-use solutions? A native implementation would require advanced mathematical and programming expertise, which a beginner (still learning C++) would struggle to master in just a few weeks of development. #b3d #CAD

Just out of curiosity, what kind of workflows do you #freecad or other CAD package users have for simple stuff you need to model for 3D printing or CNC'ing?

I start with a crude Post-It note version and try to get all the measurements in that phase, so when I get to the good part, I can just keep on drawing without killing the flow.

A post-it note it a simple drawing of a part, with all the measurements written around it.

anyone know of a 3d print model for something designed to attach to a roll of flat material (like, paper/film/etc) for cutting it into rectangles? like, something with a straight guide and a little attached razor blade and such

Re: #3dprinting & #3dDesign

I've become ... 'better ' at it, but one of the core things I'm missing is how folks do design when it needs to work with other complex parts.
For example; My #3dprinter is basically a custom component at this point. I had to design the sled to use with the rails, every component outside of the bed-base and the extrusion frame is custom or customized.

I'm looking at making a big upgrade to the hot end but nobody makes my part, and I need a cooling solution. So how do I design a fan/duct system that mounts to my hot end mount, fits all the pieces and is the right length?

It seems incredibly daunting to have to #CAD up the entire assembly from scratch. But other folks do this... Somehow? If I look for cooling solutions on any print-sharing website there are thousands of them.

What am I missing here? 🙁

I'm a big fan of TinkerCAD
( tinkercad.com ), it's a great entry-level #CAD tool with an excellent interface (which is much more user-friendly than most professional CAD software). But the new Skatcch tool they recently introduced takes it up a level and allows for almost real paramertic design.

I enjoy model airplanes, but I’ve always found it curious why #CAD software companies always seem to use model airplane engines as their models for their marketing?

Maybe I’m wrong, but it seems like most RC airplanes are electric these days.

Weirdly, the engine model seems both overly complex (from a geometry perspective) and overly simplistic (not as many parts as most people work with in actual assemblies).

Do many people today even know that it’s a model airplane engine?

Finally starting to get the hang of Fusion 360. Designed one part, modified a second one and succesfully joined them. Printing now.
Apart from the permanent frustration caused by me not knowing how to CAD, I actually like working with Fusion. I will give FreeCAD a chance but I'm tempted to figure out how to run Fusion on Linux in my ongoing fuck Windows migration process. Might be easier than the VR sound problem...
