extending partial arcs

[qnet2]

Hello all

im relatively new to mastecam drawing and have been trying off and on for a couple hours now how to extend an arc without remaking the full circle
can you do this in mastercam? surely im just overlooking a button somewhere?

thankyou

with version 9.1

modify
extend
length ( default is .050 set it less for small arcs)
click on the end you want to extend

In X you use the trim feature...which has an arrow and a ruler and a window for the actual amount of extension. Just click the arrow and put in how much you want to extend the arc.

ah, I see trim to extend.. heh heh
I learned to draw in Autocad, and so many terms in MC dont seem to follow
the same logic, or terms.

but that worked very well to extend an arc to a line close to it.

thankyou all for your time
