How do I create a raster cut in one direction ?

A customer has asked how to create a raster plan for skimming the surface of a block, with the cutter only cutting from left to right.
They found that cutting the opposite direction gives a poor surface finish.

In QuickCAM 2D, there are no options to select climb or conventional milling.
However, there is still a way to create toolpaths that follow the direction that the line was created.
In this example, I have created a raster toolpath inside a D shape using the hatch tool. Because the hatches are created left to right, it will be possible to output a toolpath that follows the same direction.
(If you wanted it to run right to left, then you would simply mirror the hatch lines)

In the post output screen, make sure the sorted tool paths option is turned off before posting the CNC G code file.

Create hatch lines with the hatch tool. You will need to experiment with the scale value in order to get the distance between lines you require (ie tool stepover)
