About the Roughness Symbols Dialog Box

Important: The fields available in the Roughness Symbol dialog box depend on the standard used by the drawing, as defined by the administrator. The fields are shortly described in tool tips from the interface.

About Roughness Symbols


  • By default, there is a 1 millimeter space between the geometry and the extension line, as well as a 1 millimeter space between the end of the extension line and the roughness symbol. Those spaces cannot be customized.
  • The roughness symbol default parameters are 1 for thickness and solid for line type. They cannot be customized.
  • At any time, you can modify the roughness symbol. For this, double-click the roughness symbol to be modified and enter the desired modifications in the displayed Roughness Symbol dialog box.

About the "Use style values to create new objects" option


  • If you have selected the Use style values to create new objects option in Tools > Options > Mechanical > Drafting > Administration tab, the Roughness Symbol dialog box is pre-filled with custom style values (as defined in the Standards Editor). In this case, Properties toolbars and the Tools Palette are disabled during the creation of the roughness symbol.

    On the other hand, if you have not selected this option, the Roughness Symbol dialog box is pre-filled with the last entered values (if any). In this case, Properties toolbars and the Tools Palette are active during the creation of the roughness symbol.

  • If you have selected the Use style values to create new objects option, you can reset the current style values in the Roughness Symbol Editor dialog box at any time using the Reset button.

Position and Orientation


  • By default, the roughness symbol's orientation is determined according to the orientation of the line it is associated with. You can modify this orientation using the Invert button available in the Roughness Symbol dialog box.
  • When this is not already the case, you can link roughness symbol position and orientation to another element, see Making an Existing Annotation Associative.
