It has been trimmed, and on the same level. I started by creating 2 circles. I then snapped a line between the circles. One of my problems is when I move the pointer over the arc to start the line I get several icons. A horizontal line with a X throught it, a X to X icon, and sometimes a circle with marks at 12pm 3pm 6pm and 9pm. Not sure what I need. I have been uning the X to X icon when it appears.

I am new to Mastercam, but this should be simple. I have browsed several forums and haven't seen a similar question. I am trying to make a slot to a depth. For some reason I cannot get the arcs and the lines to chain together. I am using a pocket profile. This makes absolutely no sense! I am using X2. Thanks in advance.
