draft working plane, normal to a straight edge

[bernd]

Is there smart way to get the working plane normal to a straight edge with FreeCAD Gui?

That would be an interesting feature to add... But there are 360° possibilities around the axis... We need a way to define the X direction too

I missed that one ... since I needed just the plane in my case ...

I needed it to make a circle which normal to an edge. I used Python to create the circle. But anyway I must admit it would be cool to set this.

What we could do it simply rotate the current WP so the current axis direction becomes the edge direction (we still need to define which direction, as a linear edge can have two). The rotation around the edge will be rather uncontrollable, though...

I would prefer the normal and binormal vector to define the coordinate system for the plane.
I work with this direction tangent/normal or tangent/binormal here

for the case here a 3rd combination normal/binormal is required
this are only some extra lines of code for another selection

So the thing would be for ex. to select two edges, or an edge and a point... But then, the user could want to place the plane coplanar to it, not perpendicular...

I think this begins to bee too many options for the working plane tool. Maybe a better path would be indeed to integrate the workplane WB tools better in it?

hi

is it this ? (not perfect if the object angle change)
