Updates the locations of all associative dimensions.
The locations of all associative dimensions in the current drawing are updated.
Associative dimensions need to be updated manually with DIMREGEN in the following cases:
- After panning or zooming with a wheel mouse in a layout with model space active; update associative dimensions created in paper space.
- After opening a drawing containing external references that are dimensioned in the current drawing; update associative dimensions if the associated external reference geometry has been modified.
Note: After opening a drawing that has been modified with a previous version, the association between dimensions and objects or points may need to be updated. You can use the DIMREASSOCIATE command to reassociate modified dimensions with the objects or points that they dimension.
