Parent page: Schematic Objects
The Comment field is a child parameter object of a schematic component (part). It is used to uniquely identify each placed part to distinguish it from all other parts placed in all the schematic sheets in the project.
The Comment is configured when the parent component part object is placed. It is not a design object that you can directly place.
The Comment can be edited graphically using what is known as in-place editing. To edit a Comment in-place, click once to select, pause for a second, then click a second time to enter edit mode.
Once editing is complete, press Enter or click away from the string to exit in-place editing mode.
There are two aspects to consider in relation to editing the Comment: editing the value of the Comment and editing the display properties of the Comment.
The Comment can be defined in the Schematic Editor as the component is being placed or after the component has been placed on a schematic sheet in the Comment field of the Properties panel.
The appearance of comments, which includes the font type, size, and color, can be configured on the Schematic - Defaults page of the Preferences dialog.
Panel page: Parameter Properties
This method of editing uses the associated Parameter dialog or the Properties panel mode to modify the properties of a comment.
After placement, the Parameter dialog can be accessed by:
During placement, the Parameter mode of the Properties panel can be accessed by pressing the Tab key. Once the comment is placed, all options appear.
After placement, the Parameter mode of the Properties panel can be accessed in one of the following ways:
A List panel allows you 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 you to target and edit multiple design objects with greater accuracy and efficiency.
The default behavior of the Comment is to auto-position it as a component is rotated during placement. If this behavior is not required, disable the Autoposition option in the Preferences dialog (refer to the previous image) either during symbol creation or after the component has been placed on a schematic sheet. Note that doing this sets this parameter to be classified as a manual parameter (meaning manually positioned parameter). Manual parameters are identified by a dot on the lower left corner of their selection box.
