General Architecture tab

General Architecture layers are used to define drawing styles to Line, Arc, and Text objects (also known as geometry objects) and every such object is assigned to a single Layer and cannot be assigned to more than one Layer at a time.

The following are some properties of General Architecture Layers that differentiate them from other drawable Managed Objects Layers:

They have no precedence property, so this tab doesn't contain the Select Variety dropdown menu or the precedence arrow buttons.
The Current Drawing Layer checkbox control in the first column is used to set the active General Architecture layer when inserting new geometry in the Design World.

All Layers,

Add New Layer: pop-out sub-dialog presents a text input field designed for the entry of a new layer's name. It also provides Add and Cancel buttons for confirming or Cancelling the creation of a new layer entry with default style properties which is placed at the bottom of the grid by default.

Caution: Please be aware that, depending on your filter choice, not all layers may be displayed in their entirety. If the number of layers exceeds the grid's limit of 500 records shown at once, the Layer Manager will limit the list, and a red indicator will appear at the top with the message (Layer list truncated – use a filter) to indicate that you should apply an appropriate filter for a complete view.
