Configuring Draftsman Arc Object Properties in Altium Designer

Created: October 18, 2019 | Updated: April 10, 2021

Parent page: Arc

Draftsman 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 Arc object properties, or those that can logically be pre-defined, are available as editable default settings on the Draftsman - Defaults page of the Preferences dialog (access 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 Arc object properties are available for editing in the Properties panel when a placed Arc is selected in the design space.

The Arc object default settings in the Preferences dialog, and the Arc mode of the Properties panel

The below properties listing applies to the options available in both the Preferences dialog and the object Properties panel.


  • (X/Y) – the X-axis and Y-axis values of the Arc's center point, relative to the document origin.


  • Radius – the radius (center to perimeter distance) of the selected Arc.
  • Start Angle – the angle of the Arc start point relative to the arc center in the X-axis.
  • End Angle – the angle of the Arc end point relative to the arc center in the X-axis.


  • Line Style – displays the Arc's current outline weight/style/color.
    • Line Weight – the line thickness. Use the drop-down menu to choose from a range of line weight presets.
    • Line pattern – the pattern style applied to line. Use the drop-down menu to choose from a range of line style presets.
    • Line color () – click to open the line color selector drop-down, which includes options for preset colors, HEX/RGB color values, the graphic selection of color shades, and variable color opacity.
