There is a file attached and polyline 16  which is in the center support attachment and the profile i need, it's not quite a straight line it has a slight bulge to it and i would like to be as accurate as possible because it butts up to another part. This is part of a garden bench project i'm working on . The Crest Rail file may bring some clarity as to how this fit's into the project. Really nice looking bench!! Thanks for any and all help.      I can feel it in my bones some one is going to to make me look like i missed something obvious.

If you know there is  buldge you must have taken a look at the point collection. Although it's quite small you can set to to zero in the points grid and it will become a straight line.
If I got correctly what you want to do.

To see the datum Dragonfly is referring to select the polyline and double click on points in the information window.

It does show a small value in the bulge field.

Hello

You can also "explode" the polyline 16 and you got an arc where you can see the radius in its properties ; in this case radius = 11.78"

Note also that maybe you may not see the arc on the display (the arc looks like a straight line) ; it's depending of the value for the Arc Display Degrees property in the options. (CamBam must be restarted after changing this setting) In my case this value is set to 0.5°

On the picture, the purple line is a straight line, with 2° for Arc Display Degrees the arc is not visible, but it is with 0.5°

Ok that's all very helpful but how do i setup a mop to accomplish this slight bulge. I don't think that i can setup a 2d operation and keep this slight bulge? Must it be a 3d mop and what is the procedure for setting this up? Thanks thusfar!

Why not ? the arc is on XY plane no ? so no problem to machine with a profile mop ..
