Displays properties of profile knuckles. A profile knuckle is an abrupt change in direction of a profile cause by the plate on which the profile is connected.
The order in which the properties display in your view depends on your configuration.
Approval State
Specifies the status of the selected object or filter. Changing this property sets the Status. The display depends on your access level. You might be unable to change the status of the object. The list is defined by the ApprovalStatus codelist.
Smart 3Dx saves an object to the database when you change that object's status. Use Undo (CTRL + Z) 
to reverse the status change.
You can only edit or manipulate an object with a status of Working.
Created By
Specifies the name of the person who created the object.
Date Created
Specifies the creation date of the object.
Date Last Modified
Specifies the date of the last modification to the object.
Hyperlink
Specifies the URL or local file path associated with the object. Click the hyperlink to open the page or object in your default browser. Point to the hyperlink to display the URL or path as a tooltip.
Description
Specifies the descriptive text associated with the hyperlink.
URL
Specifies the web address or local file name associated with the hyperlink. The URL must include the protocol, such as http: or https:, as well as the domain name. For example, https://hexagonppm.com/.
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.
Is Named by Rule
Specifies whether the object name is determined by a rule.
Last Modified By
Specifies the name of the person who last modified the object.
Manufacturing Method
Specifies the method for creating the knuckle. This list is only available if the Override Rule check box is selected. The availability of methods depends on the profile cross-section type and the plate seam condition. The list is defined by the ProfileKnuckleManufacturingMethod codelist.
Bend
Indicates that the knuckled part displays the bend radius after detailing. The Flat Bar cross-section type is supported for this option.
Split
Indicates that the knuckle point behaves as a design seam. You must run the Execute Split Command 
command to split the profile system. During detailing, the end cut rules determines
the part geometry. The plane bisecting the knuckle angle is passed to the end cut
rules. All cross-section types are supported.
Ignore
Indicates that no seam or radius is created. This applies to EA, UA, BF and Flat Bar cross-section types. This option is available when the knuckle angle is 2° or less.
Extend
Indicates that the tangential extension of the profile can extend beyond the profile seam. The software determines part geometry and applicable end cuts. The profile is trimmed to the plate contours after detailing. All cross-section types are supported.
Bend Plus Feature
Indicates that when a profile is bent about its weak axis, Smart 3Dx places a feature or features on a profile after detailing. The resulting features that are placed are based on a combination of the profile knuckle rule and the smart occurrence rules. For example, an edge feature and an insert plate feature are placed on a profile that has a concave bend with its flange oriented on the convex side. This applies to UA and EA cross-section types with heights of 200 mm or more and knuckle angles of 90° or less.
Name
Specifies the name of the selected object. If the name is too long to entirely display
in the box, point to the box to display the complete name as a tool tip. If the name
is not defined by a rule, 
User Defined displays. If this name is generated by a naming rule, 
Naming Rule displays. If you type a name in this box, Smart 3Dx automatically changes the naming rule to User Defined.
Naming Rule Prog ID
Specifies the Prog ID associated with the naming rule.
Override Rule
Indicates whether you can manually specify the Manufacturing Method. When this option is cleared, the catalog rules determine the behavior of the profile.
Parent System
Specifies the parent system for the object. Recently used systems that are appropriate to assign as the parent system for this object display in the list along with the Select from Workspace and Select from Model options. The most recently used system displays at the top.
The parent system of the object must have an Approval Status of Working before you can change the Parent System value. If the Approval Status of the parent system is not set to Working, this value is read-only.
Select Interactively
Turns on or off the interactive selection. When this option is on, you can select the parent object in a graphic view or any of the explorers.
Select from Workspace
Displays the Select Parent System Dialog with the Workspace tab open. The workspace is the subset of the active model database you specified when you started your design session. Navigate the hierarchy to select the parent system, and then click OK.
Select from Model
Displays the Select Parent System Dialog with the Model tab open. The model is all of the objects in the active model database, including those that are not part of your workspace. Navigate the hierarchy to select the parent system, and then click OK.
