Keeping a toolpath straight on a rounded edge.

[dpumaS63AX]

On my part I have a rounded contour, where I had to select the bottom line as it is a chamfer bit. However, I want to keep a straight edge when machining, I don't want it to round. How would I do that? Or is it not possible without removing the filet in the model itself.

If you hold the alt key down, you can select just the line portion of the contours. Then you can "extend geometry" to lengthen the leads on either/both ends of the line.

Where is the "extend geometry" option? I can't seem to find it, however, thank you!

Never mind I found it, thank you so much!
