Edges

The Near edge of a line is the edge nearest you in the current view. For example, for a blind hole the near edge is at the surface of the hole and the Far edge is at the bottom of the hole. You can chamfer (bevel) or round edges near edges and you can round far edges. For example you might want to round a near edge to reduce abrasion against another surface.


To set the shape of a near edge:
  1. Choose a line in your drawing.
  2. Select Line | Machine.
  3. Choose Straight , Round or Chamfer per the desired shape of the edge and enter the relevant numeric value. Use Chamfer for countersinking holes. (Most inch flat head screws are 82 degrees.) Use Straight for counterboring holes. You may need to change to an opposing view first. For example, if you have a thru hole in the Top view and want to countersink the far edge, select View | Bottom and from the bottom view chamfer the near edge.

To set the shape of a far edge:

  1. Choose a line in your drawing.
  2. Select Line | Machine.
  3. Choose Drilled for a cone shaped bottom. Choose Straight for a flat bottom. Choose Round for a rounded bottom.

To shape one segment of a contour without shaping the full contour use comments to machinist.
