Make Comments

Comments to Machinist is a line type for text and lines used to describe features that cannot be modeled directly, or for clarifications in your design.

  1. Choose menu View and select the desired view.
  2. Draw lines or text using the left toolbar.
  3. Use arrows when describing a specific area/feature of the design.
  4. Click numeric bar drop list Line Type > Comments to Machinist.

Comments to Self are for your personal reference when designing.

In some cases, Comments to Machinist may reduce cost (e.g. omitting certain machining).

Uses for Comments to Machinist

Use Comments to Machinist to describe:

  1. 3D shapes that cannot be modeled in the CAD software.
  2. Advanced [[GD&T Tolerances.]]
  3. Special instructions
  4. Minor variations (e.g. “change diameter to .503 for half run”)
  5. Advanced threading requirements that are not supported.
  6. Countersinks in 2D designs. Specify angle and size per the diagram at CAD menu Line > Machine > Chamfer.
  7. Machining existing parts.
  8. High quantity of repetitions of a hole or shape in order to avoid long computations.
  9. For injection molding, to show the desired location of the parting line, gate and ejector pins.
  10. Special finishes such as special colors or multiple finishes.

Tips for Comments to Machinist

Cross Reference

If necessary, clarify comments by referring to another comment/feature in another view (e.g. “see ___ in top view”).

Include [[Tolerances]] in Measurements

(e.g. 1.000” +/- .005”)

Avoid External References

To ensure there are no misunderstandings, refer only to aspects of the current design.
