Create the symbol geometry.

  1. Click Tools > Layers to display the Layer toolbar.

  2. Click Change Layer .

  3. On the dialog box, select the Default layer, and click OK.

  4. Sketch the chamfer geometry. This geometry can be a single line angled to the part geometry, or it can be multiple lines.

  5. Sketch two perpendicular lines at the ends of the chamfer geometry and another line opposite the chamfer geometry.

  6. Use the Trim or Extend to Next commands as needed to create a closed polygon.

  7. On the Construction layer, sketch a construction line perpendicular to the part offset face and connected at the end.

  8. Add a point constrained to the intersection of the chamfer geometry and the part edge.

  9. Constrain the chamfer to the part geometry. Do not over-constrain.

  10. Dimension the end cut on the Dimensions layer with respect to the part geometry.

    • The angle dimension should use the construction line instead of the part edge. This technique allows the chamfer to adjust properly when the part edge is not normal to the part offset face.

    • Include a dimension from the part to the part offset face. This dimension is used to adjust the depth of the chamfer.

    • Add dimensions to assure that the chamfer geometry is large enough to ensure that it cuts properly for all parameters and part orientations.

    • Do not constrain or dimension to the opposite part geometry.

    • Do not use horizontal and vertical constraints. These constraints will keep the chamfer from adjusting properly.

  11. Variables are created for each of the dimensions. If refinement of the variables is required, click Tools > Variables. Rename, change default values, and add formulas as needed.
