Re: Creating a hollow object (fan duct)

Thickness is one of the most picky functions in FreeCAD. The issues come from the third party geometrc kernel, and the FreeCAD developers cannot do much about it. With sweeps it's different. While there are also limitations, problems are also often also often user made, and the community here can h...

Creating a hollow object (fan duct)

I'm currently redesigning the fan duct for my 3d printer. My original design used two sweeps to create a single channel (picture with red object). Now I updated the design to create 3 air outlets (gray screenshot). I used the upper part from my old design. For the bottom part I used a mixture of Par...

Re: From FreeCAD To The Real World

3D Printer loosely based on the Hypecube Evolution but in the end almost completely designed in FreeCAD. Actually this was my first real FreeCAD project. I really like the performance of Asembly4 and the ability to link objects (incl. Spreadsheets) between files the design very parametric. freecad.p...

[Segfault] Crash on recompute

I noticed a reproducible segfault when trying to fix an older, broken model. The file contains a link to a file containing my global_dimensions which are used by multiple parts. Interestingly the model renders fine, if I import the link. Steps to reproduce: Download both attached files Open the atta...

Re: Macro: circle center lines

Thank you very much for creating and sharing this macro. That's exactly what I've been looking for!
During my search for a solution I found this thread discussing the need for such a tool to manually add center marks. Would be great to integrate this feature into the TechDraw GUI.

Re: Assembly 4 workbench

Is there any way to share (link) variables between (sub-)assemblies and/or parts in separate files (or link Spreadsheets into an Assembly4 part)? I'm currently trying to port my project to assembly4. It consists of many parts which are assembled in different sub-assemblies and then joined in one big...

Re: Assembly3 preview

Assembly3 uses Solvespace's solver and (from my understanding) it really does not like redundant constraints. It's homepage states Using plane alignment you constrain 3DOF: 1 translation and 2 rotations. After using plane alignment second time there is a redundant rotation. I do not have a viable s...

Re: Assembly3 preview

I'm currently experiencing some issues with inconsistent constraints. I managed to create a small example illustrating this behavior. My goal is to: - position the extrusion in the center of the coordinate system aligned with x,y,z and lock it in this position - position the metal sheet on top of th...

Re: Assembly3 preview

I'm using Assembly3 now for a while to assemble my new 3D-Printer. The only issue I have is that while the assembly gets more and more complex with sometimes having to modify sub-assemblies again I get frequent problems with "inconsistent contraints". Do you have any recommendations on ho...
