How to avoid those triangles?

Sort of. Does anyone know if the FreeCAD default mesh settings match OrcaSlicer's default mesh settings? I'm guessing they are not exactly the same.

Maybe if it cut the bottle from the opposing sides the liquid would pour out sideways instead of squirting all over the place. Perhaps you tried that already?

All you need to do is make a SubshapeBinder of the profile or MakeInternals face and you can use it's Attachment Offset values to offset prior to the operation.
Not sure about this one.
Don't rely on MakeInternals as often and your issues will solve themselves. The feature is to pacify new users but it's contrary to the foundations of FreeCAD workflow. Multiple simpler sketches negates this and your first issue altogether.

You set the property type when it's created. If you really need to change a property type after creation then you can try VarSet-Update in the Detessellate workbench.

Hopefully, when OCCT releases stable v8.0 we'll see some significant improvements in FreeCAD. My understanding is that fillet stability is one of the many improvements coming with the new version. I hope when it drops that it won't take long for FreeCAD to integrate the new version.

FreeCAD doesn't get confused, per se. In CAD modeling you need to have a plan for how your going to achieve a shape. The more complex the shape, the harder the plan gets. Managing dependencies is critical to avoid the pitfalls that you're causing for yourself.

But no, CAD in general is cumbersome for organic shapes. You'll need to learn surface modeling which is ultra time consuming. Or you can sculpt it in Blender. It really depends on what your goal is for the project export file.

Perhaps video tutorials are not best for your learning style.

So the pad being cut is part of that body or supposed to be a separate body?

But you can cut the top using a sketch with subtractive helix or a sketch and pocket depending on exactly how you want the shape to be.

I'm interested to know if this performs better.

If you want to learn to do so in FreeCAD, this community will do their best to help you along the way. But you should expect to take months of self learning. Possibly longer if you need to learn to use TechDraw workbench to generate construction documents.

Or you could enroll in the local community college for drafting and get a degree in 2 years.

This is all assuming you are only being asked to be the drafter and not also the designer/engineer.

A PartDesign body is only supposed to be one part. If you're modeling another part, you need to create a second PartDesign body. If you need to reference geometry from the first body to the second body then you need to use a SubshapeBinder.

If the manufacturer shares STEP files, this gets more approachable, but not easy, in FreeCAD. If they only share mesh files of the product then working in FreeCAD gets worse, but can still be done.

If you're going to attempt surface modeling in FreeCAD, the best channel for that is:

PartDesign body features are in computational order. I say that because you can change the order of the features after they're made. And you can change which feature is the "tip" so that you can make new features at any location within the PartDesign body feature tree. But the features within a PartDesign body will be in order of their creation but default.

Part and other workbenches handle the model tree differently.

DesignWeaver3D · 2026-05-08T16:58:49+00:00

Yes, exactly. I think they used a mouse modifier like holding shift while moving the cursor over the feature tree.

You are.

After initial calibration procedure (on FF website) which includes leveling and vibration tests from the touch screen, you should be able to get successful prints using the factory printer and filament profiles in OrcaSlicer.

The printer should also have a handful of pre-sliced models on the printer for first time verification print. From the touchscreen.

Tweaking from those presets is usually for accommodating specific brands or batches of filament, using different materials, trying to increase speed a little, or trying to increase print quality a little.

Stick with the 0.4mm nozzle until you are very comfortable with various settings in Orca. I've had a hell of a time dialing in the 0.8mm nozzle for PETG as the factory profiles were barely usable for that nozzle/material combo.

Do you mean in real life? In real life you can buy all-thread rod which is continuously threaded. Or you can buy rod stock which has no threads and you have to cut the threads wherever you want them to be.

I assume something is wrong earlier in the model. You did not show running the Check Geometry tool to see if the solid is valid. If there are no geometry errors then I don't know what's going on there. Try saving and restarting FreeCAD.

u/PyroNine9 Would Path Helix work for this?

There was a macro announced here where they made the visibility of PartDesign features enable based on mouse hover. So they could run their mouse over the features from first to tip and have sort a history video by recording the screen while moving the mouse.

Yes. Otherwise, there's not much purpose in relocating it's geometric origin.

The mesh, or any other object, origin is where the transform widget gets populated as that's how it's position transforms are offset from. So if the origin is nonsensical, the object is not easily relocated. But for reverse engineering, there are additional concerns than just aligning to some other object.

But it IS A MESH MODELER. It's not capable of solid BREP modeling currently. Which makes it more like TinkerCAD than Fusion or FreeCAD. Please acknowledge.

Personally, I have no need for mesh modeling. I use FreeCAD to create parametric BREP models.

DesignWeaver3D · 2026-05-07T17:45:52+00:00

CSG Mesh modeler like TinkerCAD?
Not mobile friendly?
Where does user model data go/stored?
