Summary

A Circle is a graphic object that can be placed on a Multi-board Design schematic document and filled with a specified solid color.

Availability

Circles are available for placement in the multi-board schematic editor as follows:

  • Choose the Place » Circle command from the main menu.
  • Click the  button in the graphic objects drop-down on the Active Bar located at the top of the design space. Click and hold an Active Bar button to access other related commands. Once a command has been used, it will become the topmost item on that section of the Active Bar.
  • Right-click in the drawing design space then select Place » Circle from the context menu.

Placement

After launching the command, the cursor will change to a cross-hair and the editor will enter circle placement mode. Placement is made by performing the following actions:

  1. Click to define the center position of the circle.
  2. Move the cursor to adjust the radius of the circle then click again to complete placement.
  3. Continue placing further circles or right-click or press Esc to exit the placement mode.
The default settings for the Circle object are available in the Multi-board Schematic - Defaults page of the Preferences dialog.

Graphical Editing

This method of editing allows a placed circle object to be selected in the design space and graphically edit its radius or location.

Select a Circle by clicking on its fill or outline. Once selected, editing handles/nodes are available at its center and perimeter.

  • Click and drag the Circle's center node to reposition it on the drawing document.
  • Click and drag a perimeter node to alter the Circle radius.

Non-Graphical Editing

Properties page: Circle Properties

The non-graphical method of editing a Circle is available in the Multi-board Properties panel, which provides editable property fields for the item that is currently selected in the design space.

To open the Properties panel and access the properties of a placed Circle:

  • After selecting the Circle object, select the Properties panel from the Panels button at the bottom right of the design space or select View » Panels » Properties from the main menus.
  • Double-click on the Circle object.
  • Right-click on the Circle then select Item Properties from the context menu.

If the Properties panel is already active, click on the Circle to access its properties in the panel.

The Circle properties can be accessed prior to entering placement mode, from the Multi-board Schematic – Defaults page of the Preferences dialog. This allows the default properties for the Circle object to be changed, which will be applied when placing subsequent Circles.

Editing Multiple Objects

The Properties panel supports multiple object editing where the property settings that are identical in all currently selected objects may be modified. When multiples of the same object type are selected, a Properties panel field entry can be edited for all selected objects. If values of a property are different for objects in the selection, the appropriate field will be shown as an asterisk (*); a new property value will be applied to all selected objects.
