How are Generated Dimensions Positioned?
Generated dimensions are positioned according to the views that are most representative. In other words, a dimension will appear on a view so that this dimension needs not be also created on another view. Generated dimensions will be positioned according to the following criteria:
- on the view on which the dimension may be generated.
- on the view on which the dimension is better visualized. For example, a view on which elements are visualized in non-hidden lines instead of hidden lines.
- on the view with a bigger scale.
- on views including more dimensions.
Generated dimensions are not computed in unfolded views.
What About the Dimensions that may be Generated from Constrained 3D Elements?
To make sure the dimensions you need to handle in your session are those expected, here is a list presenting the constrained 3D elements and the resulting associated dimensions after generation.
But first of all, remember that dimensions are generated according to the 3D constraints which belong to the object referenced by the view. In other words, in a view referencing a body, dimensions will be generated only for the constraints which are associated to this body.
A generated dimension is linked to a 3D feature or constraint, and its type cannot be modified into the drawing. For example, a generated diameter dimension cannot be swapped to a radius dimension.
Note also that for views that are generated from surfaces, only sketched constraints are generated.
