Arc Tool / Setting a Point-on-Arc" - and possible issues

Hi all,

I was doing some testing for my issue, posted as: Original post is here!

… and I have notices a ‘small’ discrepancy as follows:

Draw a horizontal baseline of 300mm (arbitrary!) and angle:= 0° Set Point-on-Line := CurrentLength / 2 Draw an arc, Radius-and-Angle in the midpoint just set Params : Radius=150, 1st Angle=0°, 2nd. Angle = 180° (no particular significance here … arbitrary value!)

Now set a Point on Angle with Angle = 0°, Length=0mm.

My results are:

20250121123300_point.on.arc

This Point-on-Arc is clearly not at Angle=0° (as reported in the properties dialogue) and the point is off by 1mm.

Is this an acceptable variation, or should I / you be concerned - I am generally a stickler for accuracy and therefore making this post.
