About the Layout Feature User Interface
The Layout Feature tab consists for commands, tabs, and shortcut menus. Click > 
Layout Feature to open the Layout Feature tab.
Layout Feature to open the Layout Feature tab.Commands
The commands are context-sensitive to the set type and constraint selected.
• Constraint list—Contains the user-defined constraints, the default is 
Automatic.
Automatic.◦ 
Distance—Offsets the component reference from the assembly reference.
Distance—Offsets the component reference from the assembly reference.◦ 
Angle Offset—Positions the component at an angle to the assembly reference.
Angle Offset—Positions the component at an angle to the assembly reference.◦ 
Parallel—Orients the component reference parallel to the assembly reference.
Parallel—Orients the component reference parallel to the assembly reference.◦ 
Coincident—Positions the components reference coincident with the assembly reference.
Coincident—Positions the components reference coincident with the assembly reference.◦ 
Normal—Positions the component reference normal to the assembly reference.
Normal—Positions the component reference normal to the assembly reference.◦ 
Coplanar—Positions the component reference coplanar to the assembly reference.
Coplanar—Positions the component reference coplanar to the assembly reference.◦ 
Centered—Centers the component reference and the assembly reference.
Centered—Centers the component reference and the assembly reference.◦ 
Tangent—Positions two references of different types so that they face each other. The point of contact is a tangent.
Tangent—Positions two references of different types so that they face each other. The point of contact is a tangent.◦ 
Fix—Fixes the current location of a component that was moved or packaged.
Fix—Fixes the current location of a component that was moved or packaged.◦ 
Default—Aligns the component coordinate system with the default assembly coordinate system.
Default—Aligns the component coordinate system with the default assembly coordinate system.◦ Automatic—Shows available constraints in the list after you choose a reference.
Automatic—Shows available constraints in the list after you choose a reference.• 
—Flips the offset direction.
—Flips the offset direction.• 
—Toggles the display of the dragger.
—Toggles the display of the dragger.• Status—Displays placement status: No Constraints, Partially Constrained, Fully Constrained, Constraints Invalid.
• 
—Displays the layout in its own window as you define constraints.
—Displays the layout in its own window as you define constraints.• 
—(default) Displays the layout in the graphics window and updates placement as you define constraints.
—(default) Displays the layout in the graphics window and updates placement as you define constraints.Both window options can be active at the same time.
• 
—Updates the layout feature geometry relative to the reference geometry.
—Updates the layout feature geometry relative to the reference geometry.Tabs
• Placement
Use this tab to enable and display placement definition. It contains two areas:
◦ Navigation and Collection area—Displays sets and constraints. The first constraint in a set activates automatically. A new constraint activates automatically after a valid pair of references is selected, until the component is fully constrained.
◦ Constraint Attributes area—Context-sensitive to the constraint selected in the navigation area.
• References
Use the References tab to select the references from the layout to include in the layout feature.
◦ Tags, Nodes and Sublayouts—Collects selected tags, nodes, and sublayouts in the layout to include in the feature.
◦ Entities—Collects selected chains in the layout to include in the feature. Click Details to open the Chain dialog box.
◦ Datums—Collects selected datum planes and coordinate systems to include in the feature.
• Options
Use the Options tab to set update options for copied geometry in the layout feature.
◦ Automatic Update—Automatically updates the layout feature when the source layout is modified and in session.
◦ Manual Update—Does not update the layout feature when the source layout is modified. Click Provide notification to show an icon in the Model Tree when the source layout is modified and in session.
◦ No Dependency—Creates a layout feature independent of the source layout.
• Properties
◦ Name—Displays the component name.
◦ 
—Displays detailed component information in the browser.
—Displays detailed component information in the browser.Shortcut Menus
Right-click the graphics window to access shortcut menu commands.
• Entities—Activates the Entities collector to select chains.
• References—Activates the Datums collector to select datum references.
• Datums—Activates the Tags, Nodes and Sublayouts collector to select tags and groups.
• Both collectors—Activates both placement constraint collectors.
• Select Reference item—Activates the collector to select a placement reference in the layout.
• Select Target item—Activates the collector to select a placement reference in the assembly.
• Clear—Clears the selected collector.
• Disable all constraints—Disables all constraints and clears the Constraint Enabled check box for all constraints.
• Enable snapping (default)—Enables snapping the layout to references in the graphics window.
• Flip Constraint—Flips the direction of a Distance or Angle constraint.
• New Constraint—Adds a new constraint.
• Default Constraint—Configure a default constraint (only available for the first layout feature in an assembly).
• Fix Constraint—Makes the constraint a fixed constraint.
• Automatic Update—Automatically updates the layout feature when the source layout is modified and in session.
• Manual Update—Does not update the layout feature when the source layout is modified.
• No Dependency—Creates a layout feature independent of the source layout.
• Provide notification check box—Shows an icon in the Model Tree when the source layout is modified and in session.
