For a better runout add another angled helix at the top.

The Extend curve from Curves workbench will provide the runout in one helix.

Is there a reason not to use it?

Re: External geometry (or alternative) best practices?

The point that should be the take away form the wiki is that attaching anything to generated geometry make the model prone to TNP. If you attach a Datum plane to generated geometry it provides no relief. Sketches have all the capabilities for location as a Datum plane. So, using a Datum as support f...

Re: May I ask how to project the side of the column pedestal to the XY plane

Using "Attachments" Tab in the post editing mode you could attach images and files to a post. Kind regards Carlo D. Thank you, I have already uploaded the screenshot. It is obvious that a projection is incorrect. Can Freecad have the function of projecting a surface onto a plane, or does ...

OK, so if a shape is padded 10mm and you enter chamfer 10mm chamfer disappear (the closest to the shape face edge it can get - 9.99mm).

That is correct. Fillet and chamfer can not consume adjacent edges or faces.

Re: Best way to center objects

Dr Marco thanks for the valuable comments. I definitely agree that "The tutorials are, typically, long on the "do this...", but short on the why". Perhaps it is my way of learning but I want to know the fundamentals first before diving into the "design of the Space Shuttle&...

Re: Chamfer fillet to a shared edge?

Hello, I just started to learn Freecad and I was wondering if in a future Freecad releases the program will be able to chamfer or fillet to a shared edge? There is a huge complaint list on a forum about the freecad features and one complaint is about chamfering (nr. 69). Blender can easily do that ...

Re: Best way to center objects

It is definitely good to think things through and organize before charging off to create a model. Often I consider how to approach the model, then after doing a bit, I realize, a different approach will be easier or more robust. Sometimes it is best to fix the earlier things before going too far. Th...

Re: How to union, intersect, etc on STL files in Part WB?

It means the mesh was not manifold to begin with.

You could try a Part WB Refine on the shape (this is a guess...never tried it).

Did you use the Mesh workbench Analyze and Repair to check the mesh.

If the mesh bad enough you may not be able to repair it.

Not a regression, but a change to the behavior.
