I am trying to figure out how the result of the discretize edge command can be rotated
green is the curve wb command result
red is the position I need them to be
I looked into rotation in the property menu but this rotates around the sketch center not the objects own center - if even existing
thus I am curious how one could rotate the command result

Re: how to rotate discretize edge result
You can choose the center in the Placement dialog.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.
Re: how to rotate discretize edge result
I looked into this too but I fail to be able to specify the rotation center right inside the discretize points.
here is a brief screen recording

so it seems specifying the axis via a datum line is what works, good enough and logical

Re: how to rotate discretize edge result
In the dialog select 2 opposite points (multiple select using ctrl key). Press Selected points button. This populates the center coordinates with the center / midpoint of the 2 selected points and sets up in the axis box the direction from one point to the other to be used as the axis of rotation. But in this case we want to use the y axis instead of the custom axis produced, so select the y axis in that control. Set the angle to the desired angle.
Re: how to rotate discretize edge result
I did select opposing points to find the geometrical center and then rotated around y
I have to try this again must have made a mistake

Re: how to rotate discretize edge result
If you've already moved/rotated an object be sure to check "apply incremental changes" so that the new placement changes are applied to the object's current placement. Think of it as a way to incrementally place an object that has already been partially placed.
The Selected points button adds the center coordinates to the center controls. Do not check the Center of Mass checkbox afterwards or else the center coordinates populated by the Selected points button will get overwritten by the object's center of mass. I'm not sure if the discretized edge object actually has a center of mass as it is a feature python object. Part -> Check Geometry does not list this as a property of the discretized edge object, which could possibly be confusing the placement dialog's center of mass algorithm.
Check apply incremental changes checkbox.
Select the 2 opposite points.
Click Selected points button.
Change axis to Y.
Set desired angle.
Click Apply or Close.
Re: how to rotate discretize edge result
Ah that makes sense - I will try that
Theoretically speaking I should be able to split the surface and rotate only the result and not the curve points.

Re: how to rotate discretize edge result
Easy to do that. Just attach the circle normal to an edge. Then rotate it as need.

Re: how to rotate discretize edge result
The attachment system works interestingly in Freecad
very logical but nested and a tick harder to grasp easily at first
Thank you all
