All,

I have used the Helix/Spiral cut to create a slot in a baseplate. How does one dimension the ever growing arc to the machine shop to build the part?

Currently I have to spend a couple hours to fake in phantom lines, arrayed at 10 degrees, with dimensions and radius callouts that grow the arc. I have to draw in a circle to get the radius at that particular point, erase the circle, pull a dimension and then edit the dimension to included the radius. There has to be a better way to communicate with the machine shop, and before you ask no they can not read Solidworks files.

Regards,

Jack
