The way I expained it to you is the way everyone here explained it to me when I got
started....even Art...
The real problem with profiling is not the tool diameter compensation, but the tool
path ordering so that cutouts within a part get cut before the part gets cut out.
Unless you are using bridging, once the part outline is cut, any cuntouts within the
part can not be cut. This is where your CAM program will come in handy.
There is a way around this. Since Mach2 now recognizes layers, put all of your
cutouts within parts on one layer and the part outline cuts on another layer, then cut
the first layer first.
The only way to know for sure which way to compensate is to know for sure wich
direction the vector is going. In Vector CAD it's real easy to tell which direction
everything is in. In Corel, it depends on the way you draw the vector, but there are no
indicators to tell you for sure which direction the vector is running. If you have a
circle and you need to compensate on the outside and the vectors are in a CCW
direction, you would compensate to the right. If the the vectors were in a CW
direction, you would compensate to the left.
If you draw a circle and drag the mouse from the left to lower right, the vectors will
be in a clockwise direction, If you drag from right to left, they will be
counterclockwise. The same applies to lines, but when drawing a box, It comes out
in the same direction regardless of how I draw it.
