Configuring Schematic Parameter Object Properties in Altium Designer

Parent page: Parameter

Schematic Editor object properties are definable options that specify the visual style, content and behavior of the placed object.

 The property settings for each type of object are defined in two different ways:

• Pre-placement settings – most Parameter object properties, or those that can logically be pre-defined, are available as editable default settings on the Schematic - Defaults page of the Preferences dialog (accessed from the  button at the top-right of the design space). Select the object in the Primitive List to reveal its options on the right.

• Post-placement settings – all Parameter object properties are available for editing in the Parameter dialog and the Properties panel when a Parameter is selected in the design space.

Location (Properties panel only)

• (X/Y) 
  • X (first field) - the current X (horizontal) coordinate of the reference point of the object, relative to the current design space origin. Edit to change the X position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
  • Y (second field) - The current Y (vertical) coordinate of the reference point of the object, relative to the current origin. Edit to change the Y position of the object. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. 
• Rotation - use the drop-down to select the rotation.

Properties

• Object type (Properties panel only) - displays the type of object (Component, Sheet Symbol, etc.,) and parameter type.
• Name - the name of the parameter.
• Value - the value of the parameter. Toggle ​ to show/hide the value.
• Autoposition - check to enable auto-positioning, meaning that the text will remain in the chosen position as the component is moved and rotated.
• Lock Parameter (Preferences dialog only) - enable this option to prevent editing of the parameter's value, either graphically in the design space
• Allow Synchronization with Database (Preferences dialog only) - enable to synchronize with the database. This option is used to control if the comment can be updated. By default, these options are enabled to always allow synchronization with the source library/database. You may disable this option to prevent that comment from being included in an update process.
• Font - use the controls to select the font, font size, font color, and add any desired special characteristics to the font, such as bold, italics, and underlines.
• Justification - click the arrows to configure the justification of the text.
