I have noticed that Bobcad 23 will pick a different start point for identical wireframes depending on where they are situated. I have a left
and right side of a part which I generated with the mirror function. The bad part here is, I'm noticing a variation of as much as .007 in the
respective sizes of the part due to the G-code being output differently for each part. In other words when a approaching an arc from the
same direction but from a more distant start point, Bob-Cad is resizing the arc slightly. That's a pretty bad problem to have because my
right part will fit perfectly but the left one will be slightly too big.
I finally decided to change my wireframe using the Contour function, which gave me increased control over the start point. I reversed
the contour on the mirror side to get the same relative direction of cut and problem solved. I finally got identical G-code for each part
with the only difference being "+" signs and "-" signs.
If anyone else has been struggling with this issue, hope it helps. Or... does anyone have a better work around?
