A point worth noting about a couple of items of functionality in AutoCAD Plant 3D 2012: if you use data-linking functionality to link to an external database, you will need to ensure that there are no spaces present in the database field names in the external database otherwise the fields cannot be mapped; a similar restriction applies to the LDT table that can be linked to an Isometric drawing, avoid spaces in the column headers otherwise the columns will not be mapped to the Title Block Attributes on the Isometric.
