Creating Roughness Symbols

You can create a roughness symbol annotation.

Important:

  • The roughness symbol allows you to respect the following standard parameters:
    • ISO
    • ASME
    • ANSI
    • JIS
  • These standard parameters can be modified usingTools > Standards... command, then selecting the Drafting category. The old roughness symbols created in previous document are migrated at edition. If you slide a new roughness symbol outside its reference, an extension line is added, its overrun is fixed to 2mm and cannot be modified.

Before you begin: Open an existing 3D shape.

  1. Activate the Front View.1 annotation plane.

  2. Click Roughness .

  3. Select the surface as shown on the part.

    Note:

    This scenario illustrates the creation of a roughness symbol by selecting geometry, but you can also select any Part Design or Generative Shape Design feature in the specification tree. In this case, the created annotation will not be attached to the selected feature, but to its geometrical elements at the highest level.

    The Roughness Symbol Editor dialog box appears.

  4. Select Ra symbol and enter the value 0.8.

  5. Click OK.

    The roughness symbol is created without a leader. To add one, see Adding Leaders and Using Breakpoints.
