Chamfer rules determine plate chamfer generation in the model:

On planar plates parts, a chamfer is based on the distance between the outer surfaces of the two parts (line 1-4 and line 3-5, which are equal for planar plates).

At a plate knuckle, the plate parts are split is along the bisecting angle of the knuckle (line 1-2). A chamfer is based on the distance between the outer surfaces of the two parts, measured from the split location (4) to the outer surface of the thicker plate (line 1-3). The chamfer location begins at the actual split location (4):

Chamfers on Offshore Structure

In some cases, chamfers are treated differently for offshore structure.

For cans, used in tubular offshore structure:

The chamfer is based on the distance between the outer surfaces of the two plate parts, measured along the normal edge of the tube (line 3-2) from the "theoretical" split location (5) to the outer surface of the thicker plate (3). The chamfer location passes through the "theoretical" split location (5):

For other offshore structure:

1. Chamfers are not placed on the length edge of a built-up flange.

2. Chamfers are not placed on the edge of a side plate or ring plate that is bounding the secondary deck plate

3. Chamfers are placed on continuity and transition plates when they are butt welded to the web of a member.

4. Chamfers are placed on the edge of a side plate and ring plate that is butt welded to the flange of a member.

The following selector class modules are included in the Visual Basic project:

RootChamferSelectorRule

The inputs to this selector rule are the chamfered part and the opposite part from the model. The chamfered part and the opposing plate part are edge-to-edge. This selector rule determines the chamfer type and calls the appropriate sub-selector rule. This selector rule provides the ChamferType, ChamferWeld, and UpdateFeature questions, and passes the answers down to the sub-selector rules. This selector rule is associated with the RootChamfer sheet of the bulkload workbook.

SingleSidedSelectorRule

This selector rule is associated with the SingleSidedChamfer sheet of the bulkload workbook.

ManualChamferSelectorRule

The inputs to this selector rule are the chamfered part and the opposite part from the model. The chamfered part and the opposing plate part are edge-to-edge. This selector rule determines the chamfer type and calls the appropriate sub-selector rule. This selector rule provides the ChamferType and ChamferWeld questions, and passes the answers down to the sub-selector rules. This selector rule is associated with the ManualChamfer sheet of the bulkload workbook.

DoubleSidedSelectorRule

This sub-selector class does not provide any questions. This selector rule is associated with the DoubleSidedChamfer sheet of the bulkload workbook.

RootTeeChamferSelectorRule

The inputs to this selector rule are the chamfered part and the opposite part from the model. The chamfered part edge and the opposing plate part are edge-to-face. This selector rule determines the chamfer type and calls the appropriate sub-selector rule. This selector rule provides the ChamferThickness question, and passes the answers down to the sub-selector rules. This selector rule is associated with the RootTeeChamfer sheet of the bulkload workbook.

DoubleSidedTeeSelectorRule

This sub-selector class does not provide any questions. This selector rule is associated with the DoubleSidedTeeChamfer sheet of the bulkload workbook.

SingleSidedTeeSelelectorRule

This sub-selector class does not provide any questions. This selector rule is associated with the SingleSidedTeeChamfer sheet of the bulkload workbook.

RootEdgeChamferSelectorRule

The inputs to this selector rule are the chamfered part and the opposite part from the model. The chamfered part and the opposing plate part are edge-to-edge. This selector rule determines the chamfer type and calls the appropriate sub-selector rule. This selector rule provides the Shipyard question, and passes the answers down to the sub-selector rules. This selector rule is associated with the RootEdgeChamfer sheet of the FT_SRDPlateChamferStyle1.xls workbook.
