Label Prefix: Text that is added prior to the label on ductwork in the layer system.

Label Suffix: Text that is added after the label on ductwork in the layer system.

Hatch Settings: The following options can be set for different types of duct hatching in the layer system. The hatching that is displayed is based upon the Airflow setting of the duct.

Display Hatch: Whether hatching is displayed on the duct.

Type: The type of hatching pattern that is displayed.

Predefined: Displays the AutoCAD hatching set in the Pattern column.
Custom: Displays a custom hatching specified in the Pattern column.

Pattern: The hatching pattern to be displayed.

Angle: The angle at which the hatching pattern is displayed.

Scale: The scale of the hatching pattern.

Hatch Flex Ductwork: Whether hatching is displayed on flex ductwork.

Layer Keys

Layer Key: This column lists all of the different items that can be inserted using the software. The names in this column are fixed. Each layer key can be mapped to a layer that will be used when that type of item is inserted on the drawing. Multiple layer keys can use the same layer.

Layer Name: This column is the layer that will be used when inserting items of that type on the drawing. The layers you can choose from are defined in the lower section of the dialog box.

Undo Layer Key Changes: Press this button to revert the layer key settings to their values when the dialog box was opened.

The layer list displays all of the layers that can be assigned to layer keys. The AutoCAD settings for each layer can be set in the list.

Layer Name: The name of the layer.

Color: The AutoCAD color number of the layer.

Linetype: The linetype of the layer.

Plot: Whether the layer will be plotted.

Lineweight: The lineweight of the layer. Only used when plotting with STBs.

Using Excel to Modify Layer Settings

The Import Layers from Excel and Export Layers to Excel buttons are used to import and export the layer settings to Excel. Using Excel is recommended when modifying large numbers of layer settings.

Export Layers to Excel: Press this button is used to export the layer settings to a CSV file that can be opened in Excel. The Save Layer File As dialog box will appear.

customization--save-layer-file-as-dialog-box

The currently selected layer system will be saved to the file you select. The file will be opened for immediate editing. When modifying the file, do not change the header rows, the first column, or the last column. Restrict your changes to the Layer Name, Color, Linetype, Plot, Lineweight, and Plot Style columns.
