Coping Plates and Shapes

The Coping command lets you trim plates and shapes with other objects.

The following Strategy options are offered:

  • Short point
  • Long point
  • Remove
  • Weld cut

NOTE: Long point coping can only be done where plates intersect. This type of coping cannot be done if the plate has to be extended to the long point.
This task shows you how to trim plates and shapes with other objects.
1. Click the Coping button . The Coping dialog box displays.
2. Select the Operated Element in your design or the specification tree.

The operated element is the plate or shape to be trimmed.

You can also first select the operated element and then click the Coping button. In this case, all the existing copings are displayed in the Coping dialog box.
3. Select Limiting Element.

Limiting elements can be surfaces, plates or shapes. Multi-selection capabilities are available.

If you select an element that is already used for coping the operated element, then the following message is displayed:

Coping Strategy, Coping Subtype and Extrapolation Offset for the selected element set during Piece Part Generation are seen in respective columns.
  4.

If no copings exist for the selected limiting element, NONE is displayed in the Coping column.

To set Coping Strategy, Right-click the respective element and select the Coping Strategy.

Note: If the Operated Element is a plate, only Remove Nibbling Strategy is available.

The selected strategy is now displayed in the Coping column.

If there is an error while creating coping, Error is displayed in the Coping column. You can click OK to exit or Cancel to undo all the copings created in this dialog box. You can also right-click and select Refresh Coping to display NONE in the coping column.
  5.

Use Coping Subtype contextual menu to set the Coping Subtype.

None in Coping Subtype indicates that it is not previously defined.

Coping Subtype ButtButt is selected when there is a plate with seam. In case a plate is limited by a plate, ButtCurr behavior is applicable. CurrCurr behavior should be selected for a stiffener attached to plate.
  6.

To set Extrapolation Offset, double click the value. If it is not specified at Piece Part Generation Command, it is taken as 0mm by default.

Note: The extrapolation offset is applied to lateral faces only.

The Coping Strategy, Coping Subtype and Extrapolation Offset values set in Coping command will override values set during Piece Part Generation command.
7. Click OK, when done.
The following is an example of a shape that clashes with the plate because the shape is limited with the plate without any coping.

Using the Coping command and a short point Strategy, the shape is limited with the plate.
The specification tree shows the coping feature created under the operated element.
