How to create a face perpendicular to another face

I would like to create a rectangular face perpendicular to another face. I have created the first face from a sketch attached to another object. I would like the new face to be at 90 degrees to the first, and touching the first. The principle is shown in the crude sketch below. I can't seem to figur...

Error using sweep on face and BSPline, what's the problem?

I have created a BSpline using the Curves workbench. I want to sweep a face along this bspline to create a solid. In the real case this is to cut some protrusions from a curved surface of another object. However, when I try to sweep a face along the BSpline, I get an error along the line of BRep com...

Re: Part.Shape.slice documentation

ok, thanks, I understand now. However, it makes it difficult to use this to create a slice at a desired orientation and desired point in space using this function. I mean you need calculate a distance to the plane which results in the plane intersecting your object at the desired point. Is there any...

Re: Part.Shape.slice documentation

Thanks, very helpful, so the distance from the placement point, in the direction specified by 'direction'? Does that mean it is impossible to specify an orientation for the slice? I had assumed direction might be the orientation, i.e the normal direction.

Re: Bad value not filtered - FreeCAD hangs/crashes

I'm interested in seeing how this works, could you possibly give me a hint for finding where in the code the property update is handled (i.e. the event that is triggered by changing a property value)? If you're using the Qt mechanism I guess I'm looking for the signal and slots that are involved. I ...

Re: Bad value not filtered - FreeCAD hangs/crashes

I hate to drag up an old thread, but I see this same issue in a recent AppImage. I start typing in the deviation box but have to delete the previous value, when I get to the point that the text: "0." is in the box, FreeCAD locks up. I assume this is because zero or some smallest possible v...

Re: Inconsistencies in Part API *At methods

It seems you made the assumption that for the parameter 0 you get the curve's start point and with the value of its length you get the end point. This assumption is wrong! The parameter range in which a curve is defined do you get with the attributes FirstParameter and LastParameter. It depends on ...
