Draft polar array with arbitrary axis

[drmacro]

If I create a Draft Polar array, by default, the array is created around the point specified in the dialog (0,0,0 if nothing is changed.

If I an arbitrary line is chosen for the Axis reference in the Properties, the array is now around the end vertex of the line.

Is there a way to have the line be the axis of of the array (i.e. the array radially around the line.)

I don't think it's the end of the line, it's the Placement of the line. TheMarkster had a similar topic recently, or at least he was involved (will have a look).

I'm intrigued to merge both topics??

Makes sense. I'd not seen that thread.

But, wonders why a Datum line works, but not a basic line? Hmm...

there is a difference if it is a plane or a solid. here is a possibility for a solid and plane

Once the array has been executed, just align its generation axis to the axis we want (obviously with minimal geometric construction) and then move it along the new axis to the position we want, or vice versa.
