General Tab (Plate Knuckle Properties Dialog) - Intergraph Smart 3D - Help

Specifies the properties of the plate knuckle.

Name

Specifies the name of the knuckle. Names generated by a rule include a Global Workshare name rule ID if the name rule ID was defined when the model database was created.

Rule

Specifies the naming rule to use to name the knuckle.

Type

Specifies the type of knuckle that you are placing.

Landing Curve Definition Method

Specifies the landing curve definition method for the knuckle.

Parent System

Specifies the parent system for the knuckle. You can define parent systems in the Systems and Specifications task. When the plate system is created, the property values for the parent system are used for the initial plate system property values. When a parent property value changes, the corresponding child property value is updated.

Override

When selected, makes the Manufacturing Method box editable.

Manufacturing Method

Select the method for creating the knuckle. This box is read-only unless the Override check box is turned on.

Bend Knuckle

The knuckle part of the plate displays the bend radius after detailing. Plates and profiles that cross the knuckle include the knuckle bend in their contour after detailing. Manufacturing parts have knuckle marking information.

Split Knuckle

A design seam is placed at the same location as the knuckle on the plate. You must run the Execute Split Command to split the plate system. After detailing, the plate edges along the knuckle bisect the knuckle angle. Plates that cross the knuckle include the knuckle angle in their contour after detailing. The landing curves of profiles that cross the knuckle follow the knuckle contour. Profiles also receive a knuckle point and are split after detailing.

Ignore Knuckle

No seam or radius is created.

Inner Radius

Specifies the inner radius dimension of the knuckle. The inner radius is generally two times the web thickness. This box is read-only if Override Rule is cleared.

Override Radius

When selected, makes the Inner Radius box editable.

Molded Radius

Specifies the bend radius to the molded surface. The molded bend radius is automatically calculated based on the inner radius, plate thickness, plate thickness direction, and plate offset if any. This box is read-only.

An example potential knuckle radius is shown in the following figure. The inner knuckle's radius is defined as the angle less than 180 degrees at the knuckle.

If the plate thickness direction is from left to right, the software calculates the following:

Molded radius at the left side = Inner radius at the left side;
Molded radius at the right side of the plate - Inner radius at the right side + plate thickness

If the plate thickness direction is from right to left, the software calculates the following:

Molded radius at the left side = Inner radius at left side + plate thickness;
Molded radius at the right side of the plate = Inner radius at the right side.
