A polygon is a non-electrical drawing primitive. It is a multi-sided graphical object that can be placed on a schematic sheet. A polygon must have at least three sides and can be filled or unfilled.
Polygons are available for placement in both Schematic and Schematic Library Editors:
After launching the command, the cursor will change to a cross-hair and you will enter polygon placement mode. Placement is made by performing the following sequence of actions:
This method of editing allows you to select a placed polygon object directly in the workspace and change its size and/or shape, graphically.
When a polygon object is selected, an editing handle (vertex) will appear at each corner, as shown in the image below.
nthvertex selected ready for editing.
With the polygon selected, click on an edge to individually select that edge. This polygon 'sub-selection' is distinguished by the associated editing handles for the edge becoming red in color.
The associated vertices for the edge can then be edited directly using the Inspector or List panel, with any changes appearing immediately on the schematic.
The following methods of non-graphical editing are available:
Dialog page: Polygon
This method of editing uses the Polygon dialog to modify the properties of a polygon object.
The Polygon dialog can be accessed prior to entering placement mode, from the Schematic – Default Primitives page of the Preferences dialog. This allows the default properties for the polygon object to be changed, which will be applied when placing subsequent polygons.
During placement, the dialog can be accessed by pressing the Tab key.
After placement, the dialog can be accessed in one of the following ways:
An Inspector panel enables the designer to interrogate and edit the properties of one or more design objects in the active document. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - the panel can be used to make changes to multiple objects of the same kind, from one convenient location.
A List panel allows the designer to display design objects from one or more documents in tabular format, enabling quick inspection and modification of object attributes. Used in conjunction with appropriate filtering - by using the applicable Filter panel, or the Find Similar Objects dialog - it enables the display of just those objects falling under the scope of the active filter – allowing the designer to target and edit multiple design objects with greater accuracy and efficiency.
