After you enter values and save the new property, you cannot make changes to the name, data type, or maximum length of the property.

When you add a unit of measure property, the property name is limited to 25 characters; for all other properties, the property name cannot exceed 30 characters.

When modifying item type properties, use the Modify <Item Type> Properties dialog box accessed from the Database Item Types display to change Display Name, Category, and Permissions. Use the Modify Property dialog box on the Database Tables tab to change all other editable properties.

A property name cannot contain any of the following characters: ! # $ % ^ & * ( ) - = + { } [ ] | \ ; : ' / ? > . , < @.

After you save a property, you can make changes to the select list for the property if the selected data type has a select list associated with it. Changing the select list for a property affects the integrity of previously saved drawing data with that property.

We recommend using ASCII characters for internal names of added properties to avoid potential failure if the plant database is accessed from a client machine with a different locale setting.
