Creating Chamfer Dimensions

You can create a chamfer dimension.

This task shows you how to:

Before you begin: In a drawing representation, create three lines. Refer to Sketcher User's Guide: Sketching Simple Profiles: Creating Lines for more information.

Create Chamfer Dimensions Manually

You can create chamfer dimensions manually.

  1. Go to Tools > Options > Mechanical > Drafting > Dimensions tab and make sure the Detect chamfer check box is not selected.

  2. Click Chamfer Dimensions in the Annotations toolbar (Dimensions sub-toolbar).

  3. In the Tools Palette which is displayed, you can choose:

    • The format of the dimension:

      • Length x Length

      • Length x Angle

      • Angle x Length

      • Length

    • The representation mode:

      • One symbol

      • Two symbols

    Important: You can also access these options using the contextual menu: at any time during the chamfer dimension creation, you can right-click to display the contextual menu.

  4. Choose the Length x Length format and the One symbol mode .

  5. Select the element to be dimensioned.

  6. Select a reference line or surface.

  7. You have two options:

    • Click the sheet to end the dimension creation. The chamfer dimension is computed with an implicit second reference line that is perpendicular to the first one.

    • Select a second reference line or surface. In this case, the chamfer dimension is computed according to both reference lines you selected.

    Important: In a Generative Drafting context (i.e. in the case of a generative view), you must apply the second option, i.e. you must explicitly select the second reference line.

    In any case, the dimension is associated to all the elements you selected.

Create Chamfer Dimensions Using Chamfer Detection

You can create chamfer dimensions using chamfer detection.

Note that chamfer detection is provided as a help in selecting chamfers. However, depending on the geometrical configuration, it may not detect all chamfer types. If your chamfer is not detected, you can still create the chamfer dimension manually as explained below.

Open a drawing representation containing at least one chamfer.

  1. Go to Tools > Options > Mechanical > Drafting > Dimensions tab and make sure the Detect chamfer check box is selected.

  2. Click Chamfer Dimensions in the Annotations toolbar (Dimensions sub-toolbar).

  3. In the Tools Palette which is displayed (as well as in the contextual menu), you can choose the format of the dimension and the representation mode. For more information, refer to step 3 in Creating chamfer dimensions manually.

    Choose the Length x Length format and the One symbol mode .

  4. Fly the mouse over the element to be dimensioned. You can notice that, depending on where you position the cursor, the auto-detection agent indicates a different order for taking elements into account when creating the chamfer dimension:


    • 1 indicates the element to be dimensioned.

    • 2 indicates the line which will be used as the first reference.

    • 3 indicates the line which will be used as the second reference.

  5. Click when you are satisfied with the order offered by the auto-detection agent. For example, click to accept the 3 - 1 - 2 order. The chamfer dimension is computed according to the first and the second auto-detected reference lines.

    Important: At this stage, if you are not satisfied with the order you just accepted, or if your chamfer is not detected, you can still click to select the first reference line, and, optionally, the second reference line. This amounts to creating the chamfer dimension manually.

  6. Click to end the chamfer dimension creation.



    The dimension is associated to all auto-detected elements.
