Defining Built-in End Cuts

This task shows you how to define a built-in end cut. This is usually done by an administrator.

These steps apply to Structure Functional Design, Ship Structure Detail Design, and Structure Design applications.

A built-in end cut is created by subtracting a volume from a profile (shape/stiffener). This volume is modeled using a set of parameters. The administrator defines these parameters and assigns a name to the end cut. The advantage of using a built-in end cut is that the data size of the model is smaller.
 

Built-in End Cut Parameters
  The shape of a built-in end cut is defined by a set of parameters, used in different combinations. There are twelve parameters, ten web (A1,A2,B,D1,D2,G,L1,L2, R1, and R2) and two flange parameters (B1 and B2).The images given below explain these parameters.

 

Most combinations of these parameters can be used to create built-in end cuts. However, usage of certain combinations is restricted as these result in conflicting geometry. For example,

  • R1 with A1
  • R2 with A2 
 

Creating a Built-in End Cut
  The following explains how to create a web snipe end cut.

                          

1. Create a Design Table or modify the sample design table, BuiltInEndcutDesignTable. This sample table is provided with the application. It is located in the following folder:

.../OS/startup/EquipmentAndSystems/Structure/DetailingFeatures

 For more information, see Design Tables in Infrastructure User's Guide.

Enter the end cut name (PartNumber) and values for the required parameters. In the given example, appropriate parameter value is assigned to create a Web-Snipe-Radius-R1 end cut.

To add a new end cut, add a new row in the table.
2. Add the design table to a CATPart. A sample CATPart, BuiltInEndcut.CATPart is provided with the application. It is located in the following folder:

.../OS/startup/EquipmentAndSystems/Structure/DetailingFeatures

Add this CATPart to the catalog. For more information about adding a CATPart to a catalog, see Adding Slots, End Cuts and Small Assemblies Templates to a Catalog.

The image below shows the Web-Snipe-Radius-R1 end cut placed on a stiffener. For more information about placing end cuts, see Placing End Cuts.
