Turner Cube meshing with solid faces

Post by z-y »

Hi,

I'm quite new to FreeCAD and have been following this tutorial to get my bearings.

I've completed the cube and attempted to export to stl (and subsequently to mesh the part) in an attempt to use in Cura to 3D print however, the hollow faces all become solid when I mesh. I've exported the meshed part, opened in Cura and FreeCAD to the same result.

I've done some reading but I'm not sure where I'm going wrong.

Welcome to the forum.
In your file sketch001 is not good, you can see that in the treeview because there is a red mark on the sketch. Deleting and remake the constraints solve the problem.
One more advice: Do not use such old tutorials the Freecad program has changed a lot. Recent tutorials you can find here https://wiki.freecadweb.org/Tutorials

If you want to slightly speed up the process you can use the attached macro. Firstly you need to edit line 24 and put in the correct location of your Cura install. If you are using Part Design Wb make sure the Body is selected before running the macro. Note if you end up building assemblies, you will need to hide all the components you don't want to 3D print and please don't thank me, I didn't write the code, the author is on line 5.

Thank you - this worked a charm and makes sense.

When a step in the construction tree has a problem (red icon), all the downstream construction is not recomputed (blue icon).
So the mesh of the last step will select the last working step.
