Creating Length Dimensions

You can create a length dimension annotation.

  • When the dimension supports are related to a parameter (sketch constraints, knowledge, etc) for which tolerances are still defined, they are set to the dimension tolerances.
  • Minimal distance can be created between canonical surfaces (revolution or planar surfaces) or the projected edge, in the current annotation plane, of a non-canonical surface.

Before you begin: Open an existing 3D shape.

  1. Activate the Front View.2 annotation plane.



  2. Click Dimensions .

  3. Select the surface as shown on the part.

  4. Click anywhere outside the geometry to create the dimension.

    The dimension is created.



  5. Drag the dimension.

    The Dimension Properties toolbar displays five combo boxes:

    • Line Type to select the dimension line attachment.
    • Tolerance Description to display the tolerance according to a standard.
    • Tolerance to valuate the tolerance dimension.

  6. In the Dimension Properties toolbar, select TOL_NUM2 in the Tolerance Description combo box, and +-0.5 in the Tolerance combo box (the dimension is still selected).

    Tolerances are displayed with the dimension.
