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.x annotation plane.
  2. From the Annotation section of the action bar, click Dimensions .
  3. Select the element for which the dimension needs to be created.


  4. Click in the 3D area to place the dimension.
    The dimension is created.



  5. Drag the dimension.
    The Dimension properties in the Object Properties panel displays the following lists:
    • Dimension Line to define the dimension line attachment.
    • Tolerance Description to display the tolerance according to a standard.
    • Tolerance to valuate the tolerance dimension.
  6. Select TOL_NUM2 in the Tolerance Description list, and +-0.5 in the Tolerance list (the dimension is still selected).
    Tolerances are displayed with the dimension.
