Preparing Geometry

Here is a drawing "shape2.dxf" which I drew with QCAD and opened in HeeksCNC.

The sketch has all the geometry in one sketch.

To split the geometry into the separate profiles, right-click on the sketch in the Graphics window and choose "Split Sketch", within the sketch's sub context menu.

The profiles will be made as separate sketches, ready to be used for profile and pocket operations

For drilling operations, Point objects must be added.

To do this, it is best to select "Centre" from the snapping tool bar.

Then choose "Start Drawing Points" from the tool bar

You can then click on the circles, individually, to add points at the centre points.

These points will appear in the Objects window and can be used in drilling operations.
