I use the one in CadTools and it has window that opens and you can adjust the parameters and create a custom vehicle.

My fault for not stating all the angles were to be measured CW or CCW from 0°.

Indeed, it is sir. Thank you for looking into this issue of mine. Although I'm not certain of what causes the error that I'm seeing, I have the same "Macro" written out on one of my gaming devices, it works, until AutoCAD becomes a dyslexic child. That caused me to look for an "internal" method to AutoCAD. Starting at around 2°, these were my results this morning. Multiple completely different random starting lines. I'm not sure what you mean by changing the start point, I want it to start on the 0° axis from 0,0. I do not use "Dynamic Input" or "Dynamic UCS".

yes, ATTSYNC is the magic command. If you update blocks with attributes you only change future blocks, not those already in the drawing. The ATTSYNC command syncronises all blocks to the new definition. It is possible to do a lot of damage to a block by deleting attibutes and not attsyncing it - and there have been plenty of "help me" requests here to prove it.
