Configuring PCB Room Object Properties in Altium Designer

Parent page: Room

PCB 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 the following way:

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

  

Properties

• Name – the current name of the room (and the associated Room Definition rule). This can be changed as required. As well as helping identify each room, the name can be used to target a specific room in a design rule.

• (X/Y)

  • X (first field) – this field shows the current X position of the first vertex of the room relative to the current origin. Edit the value in the field to change the position of the room relative to the current origin. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. Default units (metric or imperial) are determined by the Units setting in the Other region of the Properties panel in Board mode (accessed when no objects are selected in the design space) and are used if the unit is not specified.
  • Y (second field) – this field shows the current Y position of the first vertex of the room relative to the current origin. Edit the value in the field to change the position of the room relative to the current origin. The value can be entered in either metric or imperial; include the units when entering a value whose units are not the current default. Default units (metric or imperial) are determined by the Units setting in the Other region of the Properties panel in Board mode (accessed when no objects are selected in the design space) and are used if the unit is not specified.
  The icon to the right of this region must be displayed a (unlocked) in order to access the below fields. Toggle the lock/unlock icon to change its lock status.

Outline Vertices

This region is used to modify the locations of existing vertices of the currently selected room object. Arc connections between vertex points can be defined and support is also provided for exporting vertex information to and importing from a CSV-formatted file.

• Vertices Grid – lists all of the vertex points currently defined for the room in terms of:

  • Index – the assigned index of the vertex (non-editable).
  • X – the X (horizontal) coordinate for the vertex. Click to edit.
  • Y – the Y (vertical) coordinate for the vertex. Click to edit.

  • Arc Angle (Neg = CW) – the angle of an arc that is drawn to connect this vertex point to the next. By default, connections are straight line edges with this field remaining blank. Click to edit then enter an arc angle as required. Entry of a positive value will result in an arc drawn counterclockwise. To draw a clockwise arc, enter a negative value.

    Straight line edges are used to connect one vertex point to the next. If you would rather have an arc connection, enter a value for the required Arc Angle. Entry is made in the field associated to the source vertex point with the arc being from this vertex to the subsequent vertex below in the list.
