About Scallops

The scallops are the openings created at intersections for draining water and venting out air. The scallops are created at the corner or the edges of the panels and plates.

The scallops are similar to the standard openings and are created with the position strategy. You can create the scallops using the following modes:

  • Limit/Limit: creates scallop at the corners.
  • Limit/Offset: creates scallop on the edges.

When you select a panel or a plate, the scallops to be created at the corners are automatically detected. By default, the scallop type is Limit/Limit. You need to select the corners to define the scallop. If you do not select any corners to define the scallops, the scallops are created on the edge.

Scallops do not take into account the flanges on the plate's edges.

Position Strategy

  • Limit/Limit:
    • Limit1: First reference for the scallop.
    • Limit2: Second reference for the scallop.
  • Limit/Offset:
    • Limit: First reference for the scallop.
    • Reference: Select the reference at which the scallops are to be created.

      You can select multiple references. Click to view the list of the selected references. You can replace and delete the required reference by clicking and respectively. You can define the individual offset value for each selected reference in the Element List dialog box.

Contour

In the Contour area, select the contour type and the contour name. This list is generated from the opening table specified in Data Setup.

In the Type list, the types of the opening are:

  • Rectangular
  • Round
  • Oblong
  • Catalog
  • Snipe
  • Clearance

The snipe and clearance types are available only for the Limit/Limit position strategy.

For the Catalog type, you can create a scallop by selecting a user-defined contour.

The opening references for the catalog, snipe, and clearance types are added in the Structure Reference Catalog or the Structure Reference Library in Data Setup.
