Update CAD on Grid Changes Preference

The Update CAD on Grid Changes is a drawing preference made from Smart Client. This setting controls whether changes made in the Smart Client grid are automatically updated in the BIM model or CAD drawing, if currently open. The Smart Client syncs renamed identity fields (for example, the Room Code or Equipment Code) and model-driven values. The Smart Client respects the setting on model-driven values -- those that should always originate from the model -- and does not update those values.

You enable or disable the Update CAD on Grid Changes setting in the Drawing Preferences set from Smart Client. The setting affects both the Extension for AutoCAD and the Extension for Revit. See Setting Drawing Preferences.

If enabled, the following rules dictate if the CAD drawing is updated or not.

A CAD drawing is already open in either AutoCAD or Revit.
That open drawing is recognized as an Archibus drawing, that is, it has a record in the afm_dwgs table.
The grid is displayed in the Smart Client for records that are considered CAD Asset types, such as rooms and equipment
A change is made to a record(s), and the values being changed meets any of the following criteria:
- Is part of the primary key
- Is the standard value
- Is part of the CAD asset label
The end result of a CAD update initiated from the Smart Client grid is as follows:
- For AutoCAD, the XData and Label will both be updated.
- For Revit, the element properties will be updated.
