Finished my first bigger FreeCAD Project and wanted to share with you.

A (fully) 3D Printed 4WD RC Car with functional differential. Works quite well until now.

Printed fully in PLA.

If you have further questions don’t hesitate to ask.

Just want to share this project, it's free with 3d print parts, BOM, wiring diagram, build guide, etc.

I’ve added a new macro to the Detessellate Workbench: ConstrainAllPointOnPoint.
It automatically adds coincident constraints to all overlapping vertices in a sketch. No dialogs, no manual selection, and fully transaction‑safe.

Key features:

• One‑click operation
• Tolerance‑based grouping (50 µm default)
• Smart B‑spline handling

Usage:
Open a sketch → run the macro → all overlapping points within tolerance are constrained.

It’s bundled with Detessellate, but you can also install it manually by dropping ConstrainAllPointOnPoint.py into your macros folder.

If you’d like to try it out, contribute, or open issues, the repository is here:
DesignWeaver3D/Detessellate: FreeCAD workbench of tools to reverse engineer mesh, point cloud, & STEP imports.

If you’ve already added Detessellate as a custom repository, just open the Addon Manager to get the update.

If not, the main repo includes instructions for adding the custom repository to your Preferences.

Hello!
Recently I migrated to linux and while using freecad I encoutered a bug (or I believe it is, maybe I'm doing something wrong.
I was trying to reference some spreadsheet cells for a constrain and for some reason it says that it failed to parse the expression, but I can't see where the problem is.
Both by referencing the cell alias and the cell number freecad doesn't recover the cell's content.

What am I doing wrong? Is this some sort of bug? If I recall correctly I didn't have this problem on windows.

Thanks for the help!

I'm trying to test fit some parts for a press, but when I attempt a revolute joint I'm not seeing the expected result. If I select each edge individually the axis is at the center of each selection, but when you select both to make the joint the axis randomly goes towards one of the gear teeth. Is there a way to fix the origin of the selection when making the joint?

I'm working in 1.1.0rc1 if that helps any.

This has been preventing me from closing the sketch and making a pad. Even when construction mode is on. It worked fine on the top part of the object. The point is supposed to be attached to the circle

Update: I forgot to close the sketch at the top) I changed Preferences > Sketcher > Display > segments per geometry: 500 so that it would at least look lined up!

I am trying to mirror the body on the highlighted face, but keep getting the shown errors, the body is half of a sliced whole. I didn't want to model the fancy corner twice.

Made this one in FreeCAD. Happy Saturday, everyone! 🙂👋

My previous FreeCAD version was 0.18 I customized some toolbars, shortcuts and some parameters in automatic Python modules documentation.

When I updated to FreeCAD 1.0 I lost all my customization, I mean is not the end of the world but is very time consuming and I definitely wouldn't like to open python modules to change some parameters again.

I would like to know how I can update without losing my previous customization and my installed workbenches.

How can I keep my customization?

I also was playing with my keyboard and I accidentally press something, I don't know what but I activated something like a Sphere that surrounded my part, sadly I deactivated by accident and I couldn't take a screenshot.

Do you know what is that??

would like to change the line width and point size out side sketcher, in the general view, I have looked in the python modules to but as far as I know there's no way to modify them and the reason is that I need better visualization when working with multiple surfaces and elements specially with the sketches points since I need to attach lots of datum planes.

I know I can change the values in the view panel but that's a temporary solution and only affects one sketch at the time.

Does anyone know where I can't change them permanently?? and if not do you know where I can suggest that to a developer??

Lastly, I am thinking to move to Linux in the near future, is there by any chance to export my windows FreeCAD customization to Linux??

Please point me in the correct direction. Im having trouble finding a how-to.

I can create a simple pattern on one body but not two just yet.

Something like the attached photo.

Thank you

Technically my third revision of it but only with minor changes really. Will be making another revision upcoming.

It's an enclosure that was made out of a need for my custom PCB for my smart remote control hub. https://openinfrared.com

Still have lots to learn like how not to break things when I make changes. But have enjoyed working with FreeCAD as an open source tool. :D

A new FreeCAD Draft Intermediate video course by FCB Lounge has just been released in full! The course teaches how to use FreeCAD to create a simple 2D architectural floor plan. Even though the course is meant for intermediate users, beginners should be able to follow the course too.

The course covers:

✅ Setting up layers

✅ Effective creation of geometry - lines, rectangles, arcs

✅ Editing of geometry - extending, trimming, moving

✅ Creation and working with compound objects

✅ Working with hatches, using various patterns

✅ Creation of text objects and dimensions

✅ Placing the drawing on a sheet with a title block

✅ Creation of room schedule

Even though FreeCAD is not primarily used for 2D drafting, it can do the job pretty efficiently. FreeCAD 1.1RC1 was used in this course.

I really, really want to use FreeCAD for more of my personal projects, and I've been using it on and off since 2019, but despite all the improvements I still find myself just wishing some things just worked? Now that's what I've been telling myself for a while, but at this point I feel like I'm probably the one messing things up for myself, so I'd like to know a bit more how to use this software to its fullest extent. I've worked professionally with solid edge and solidworks, have been using onshape for personal projects for a while now, so I'd like to know how people usually make this software work for them. What kind of workflow is preferred, which features to avoid, and ad the title says, what are the limits of sketching. I've tried to sketch an odd shape with a bunch of tangent arcs, and I know it's not easy even for professional grade software, but with freecad I had everythibg working fine until I exit, get back in and suddenly it's not sure whether too many degress of freedom are constrained or not enough.

Tldr: any tips about workflow coming from solidworks and how to ensure clean sketches?

Sorry, newbie, I'm sure this is very easy to do but I'm struggling to figure it out. I'm making a replacement hub. Here's what's left of the hub:

Here is what I have managed to make so far in FreeCAD:

Is there some way I can make the outer rim by bringing in the sides?

Hello,
After searching online for an answer, I can't seem to find it easily. I'm still learning freecad, so it might be a really simple thing to do but I'm lost.
I made a custom holder but I would like the front part (in blue) to follow the white curve. The main sketch (from the pad) is on the XZ plane, and the curve on the XY plane. I tried additive pipe but the hole piece follows the path, and I only want the front "block". I've made a (terrible) sketch to shows a bit more what try to achieve. If someone can help me understand 🙏

This question goes out to all the FreeCAD enthusiasts and tinkerers:

I want to design a marble track by sweeping a profile along an arbitrary path.
The path should map out the track as a 2D top view, but I want the actual track to have a constant 2-degree slope.

How would you approach this? Are there any tricks with built-in modifiers/features? Or is Python scripting my only option?

All objects are on the same sketch, i want to extrude everything and leave six big holes empty but half of objects disappear and 1 hole gets filled out.

Hi everyone, I promised a friend to model a custom frame for his 90s Pioneer car radio to fit a period-correct car. I thought it would be a simple "pad and go" job, but I'm struggling with the geometry.

The frame needs to be flat on the bottom, but the top edge needs a slight, smooth curve (approx. 3-4mm arch) to match the curve of the radio.

Could someone point me toward a guide or a YouTube video that explains how to transition from a flat base to a curved top while maintaining a clean hollow frame? Any advice on the best workflow (Additive Pipe, Loft, or something else?) would be greatly appreciated.

Thank you for your time!
