Creating Driving Dimensions

Driving dimensions are dimensions that drive associated geometry.

You can create the following types of driving dimensions:

  • Length
  • Distance (and distance offset in the case of two concentric circles)
  • Angle
  • Radius
  • Diameter

Before you begin:
  • Select Me > Preferences > App Preferences > 3D Modeling > Mechanical Systems > Drafting > Display and select the Activate elements' analysis check box.
  • Then, click Configure and in the Elements' Analysis dialog box, select the Dimensions driving 2D geometry check box, and identify the color that will be assigned to driving dimensions (you can change it if you want).

When creating driving dimensions, why is the Drive Geometry option unavailable for some geometrical elements?
  1. Double-click the dimension that you want to turn into a driving dimension.



  2. In the Dimension value dialog box, select the Drive geometry check box.

    This dimension drives the geometry.

  3. Type a value to modify the dimension and click OK.

    The geometry is updated according to the new driving dimension value.



  4. Click anywhere in the sheet to create the dimension.

    The color defined for the Dimensions driving 2D geometry in the Elements' Analysis dialog box is assigned to the driving dimension.



    Notes:
    • Once the Drive geometry check box is selected, you can access a context menu and configure the values properties according to your needs. For more information about the available options, see the 3DEXPERIENCE Native Apps.
    • When a driving dimension is created between two parallel lines, then their parallelism is constrained. Therefore, if a geometrical parallelism constraint was previously applied to them, this constraint is destroyed. This avoids an overconstrained situation.
    • Dimensions created along a reference direction cannot be driving dimensions, that is they cannot drive the geometry.
