Modifying a Pattern

This task will show you how to modify the pattern of a view.

Patterns are used for area fills or, as is the case in this scenario, when cutting through material in section views/cuts or breakout views, for example. 

Open the GenDrafting_exploded_isometric.CATDrawing document.
  1. Select the pattern be modified in the Section view.

  2. Select Edit > Properties.

    You can also right-click the pattern and select Properties.

  3. In the Properties dialog box that appears, click the Pattern tab.

  4. To define your own pattern, choose a pattern type from the Type drop-down list:

    • Hatching

    • Dotting

    • Coloring

    • Image

    For the purpose of this scenario, select Dotting from the  Type drop-down list.

    If you want to choose from the various patterns available, you can also click the [...] button. This will display the pattern chooser, from which you can make your selection.

  5. In the Pitch field, type 5 mm.

  6. From the Color drop-down list, select black, for example.

  7. Uncheck the Zigzag field, and then click OK. The pattern is modified.


  • Each part is assigned a specific pattern. Therefore, each time you modify a pattern using the Properties dialog box, all the patterns of the views generated from this part will be modified. These modifications will be applied to all existing sheets.
  • Pattern properties are not persistent: for instance, the pattern may change after switching an exact view to the approximate mode (and vice versa), or after uncutting then cutting a part in all views.
  • Patterns are defined in the standards. For more information, refer to Pattern Definition.
