About the Minimum Distance DimensionLimitations
 A minimum distance dimension cannot be part of a dimension system.
 A minimum distance dimension cannot drive the geometry.
 A minimum
distance dimension cannot be created between technological features which have been created with Technological Feature Dimension
.
 If the minimum distance between two geometries
can be reached at several different locations, only one is selected by the minimum distance dimension.
 When a minimum distance dimension is
created, it cannot be changed into a distance dimension.
 The measure of minimum distance is
performed on the geometry projection in the dimension view plane, so that minimum distance dimension cannot be created as a true length dimension,
within an isometric view.
 As for
all dimensions, it is not possible to create a minimum distance
dimension on a surface that is not canonical.
Update
As for all dimensions, any update or geometry modification recomputes a minimum distance dimension.

A minimum distance dimension cannot be null. If geometries are modified and are intersecting with each other, the update will not recompute the
minimum distance dimension.
