Drawing Rule dialog - Attribute Labels tab

Contains controls for manipulating Mechanical discipline label symbology and also used to define custom label variables. Component information about part/family, dimension/diameter, insulation/lining, status, material, pressure class and airflow can be attached to resymbolized graphics during the drawing composition process or at any time in a Promoted Building dynamic view.

Setting	Description
Attributes	Contains list of available member attributes describing Mechanical components.
Custom Labels	Lists custom labels, managed by user. You can add, copy or remove the custom labels in Mechanical rules. Add – Adds New Label in the Custom Label's tree. You can rename it to suitable name. Copy – Copies the selected custom label in the end of list, adding "- Copy" suffix to the label name. Delete – Removes the selected custom label from the list.
Display for Selected Attribute	When on, the selected attribute's settings become active. Settings applicable to currently selected attributes only get enabled.
Position	Controls the location of the label relative to the resymbolized component. % of member length - Applies a percentage to locate the label along the length axis of the resymbolized component. The value is calculated from the start point (end 1) of the component. Distance from end 1 - Applies a numeric value to locate the label along the length axis of the resymbolized component. Value is calculated from the start point (end 1) of the component. Distance from end 2 - Applies a numeric value to locate the label along the length axis of the resymbolized component. Value is calculated from the end point (end 2) of the component.
Above/Below (label placement)	Controls label's center line offset distance by selecting a direction and entering a value. Selecting Above places the label above the resymbolized component. Selecting Below places the label below the resymbolized component.
x Text Height	Used to enter a numeric value to set a label offset for placement above or below resymbolized component based on the label's text height.
Text Style	Selects an available text style for labels. Use the Text Styles tool to load or create text styles.
Height	Used to enter a numeric value for label text height.
Width	Used to enter a numeric value for label text width.
Font	Selects an available font for labels.
Justification	Sets the alignment of the text used in the label. The setting is independent of the label offsets.
Level	Sets the level for labels.
Color	Sets the color for labels.
Weight	Sets the line weight for labels.
Format	Displays label format that is currently active. The Format allows for user defined notes to be added when label is created. There are no restrictions to what can be typed in this field. The drawing rule generated attribute label is parenthesized by the expression `< %VALUE% >`. Two part dimension labels are separated `< %VALUE% x %VALUE% >`. The format also supports a `%SHAPE%` keyword. When required, pre-pending or appending the string with `%SHAPE%` adds the shape symbol to the resulting string. Rectangular ducts do not have a symbol. Units - Applicable for Length attribute. Sets the units to master or sub units or none.
Add Attribute	Opens the Define Custom Label Variable dialog, where you can define the attributes string using the options for what to display and in what format.
