Available in: Sketch, Part Studio

Shortcut: shift+d

Dihedral analysis displays the dihedral angle of selected edges in Part Studios.

When in sketch mode, or while editing a sketch, you can use the shortcut Shift+d to automatically open the Dihedral analysis dialog. Shift+d acts as a toggle: opening and closing the dialog while selections persist.

Any changes to selections persist for the next time you invoke the tool. If you make a pre-selection before opening the tool, the tool opens with just that selection, clearing any other selections made previously.

  1. In a Part Studio, click the Show analysis tools icon () in the bottom right corner of the interface.

  2. From the menu, select Dihedral analysis to open the dialog box:

  3. Select an edge or edges to show the dihedral angle.

  4. Select your preferred unit of measurement.

    • Max - When an edge (or edges) is selected, the maximum dihedral angle is displayed.

    • Min - When an edge (or edges) is selected, the minimum dihedral angle is displayed.

  5. Optionally, select Enable threshold display to activate the customizable high and low threshold fields.

  6. Optionally, use the Scale slider to adjust the length of the dihedral combs.
