About the Offset Geometry Feature User Interface
The Offset Geometry tab consists of a tab with commands, tabs, a dragger, and shortcut menus. Use the dragger and shortcut menus for expediency. Use the tabs for rule-based surface set selection, selecting attachment references chain, and viewing your selections.
Shortcut Menus
Right-click the graphics window to access shortcut menu commands.
Selecting surfaces:
• Geometry Rule Surfaces—Opens the Geometry Rules dialog box.
• Shape Surfaces—Opens the Shape Surface Sets dialog box.
• Tangent Surfaces—Selects tangent surfaces.
• Solid Surfaces—Selects all solid surface.
• Offset Surface Set—Type of surface set selected.
Propagation and attachment:
• Optional references
◦ Pattern/Symmetry/Mirror Feature—Selects a pattern, mirror, pattern recognition, or symmetry recognition feature that is used to propagate the offset geometry feature to all instances such that the pattern, mirror, or symmetry is maintained.
◦ Extend and intersect—Extends the surfaces of the selected offset geometry and the remaining surface until they intersect.
◦ Create side surfaces—Creates surfaces that connect edges to cover the hole left when a surface is offset.
◦ Bounding edges—Collects edges that act as boundaries for geometry.
◦ Splitting surfaces—Collects the surface to extend when splitting surfaces.
◦ Extending surfaces—Collects extending surfaces to split.
• Clear—Clears the last selection collector.
• Add condition—Opens the Conditions dialog box so you can add a new condition, and select a geometric reference and a type of condition.
• Create default conditions—Adds default conditions to the vertices of the dragged geometry. The vertices are automatically created to maintain tangency.
• Next solution—Finds the next solution.
• Previous solution—Finds the previous solution when there are multiple solutions.
Commands
Use the following commands to set the offset dimension and direction.
• 
—Type a number in the box to set the offset dimension.
• 
—Reverses the direction of the offset.
|  You can click the arrow in the graphics window to reverse the offset direction. |
• 
—Modifies the geometry that is next to the offset geometry to maintain existing tangency.
Tabs
Use the tabs for selecting surfaces to offset, attachment of the offset surface to the base geometry, and defining splitting and extending surfaces in addition to other tasks.
• References—Shows the surfaces to offset. Click Details to open the Surface Sets dialog box.
◦ Transform selected attachment rounds/chamfers check box—Offsets the selected rounds and chamfers that attach the offset geometry to the model. If not checked, the selected attaching rounds and chamfers are removed and optionally recreated.
• Attachment—Shows options for attaching offset geometry to original geometry.
◦ Attach offset geometry (default)—Reattaches the offset geometry to the original solid or quilt.
◦ Create round/chamfer geometry (default)—Specifies whether to create round or chamfer geometry after the selected geometry is offset and attached. Closes gaps created by offsetting geometry and recreates rounds or chamfers in the new location. Available when Attach offset geometry is selected.
◦ Store attachment properties—Store the attachment properties to use when you reattach the offset geometry to the model. Available when Attach offset geometry is not selected.
◦ Create side surfaces—Creates surfaces that connect edges to cover the gap left when a surface is offset. Click Details to open the Chain dialog box.
◦ Extend and intersect—Extends the surfaces of the selected offset geometry and the remaining surface until the two intersect. Click Details to open the Chain dialog box.
◦ Bounding edges—Collects edges that act as boundaries for geometry. Click Details to open the Chain dialog box.
◦ Next—Finds the next solution.
◦ Previous—Finds the previous solution when there are multiple solutions.
◦ Maintain solution topology—Fails regeneration when the model changes and the same solution type cannot be reconstructed.
• Conditions—Contains the conditions for controlling tangency propagation.
◦ Create default conditions check box—Adds default conditions to the vertices of the dragged geometry. The vertices are automatically created to maintain tangency.
◦ Conditions list—Shows the user-defined conditions for controlling tangency propagation.
▪ Add new—Adds a new condition.
▪ Reference collector—Shows the geometric entity to which the selected condition applies.
▪ Type—Displays the condition type applied to the selected reference.
• Options
◦ Propagate to Pattern/Symmetry—Shows a pattern, mirror, pattern recognition, or symmetry recognition feature that is used to propagate the offset geometry feature to all instances such that the pattern, mirror, or symmetry is maintained.
◦ Extending surfaces—Collects extending surfaces to split.
◦ Splitting surfaces—Collects the surface to extend when splitting surfaces.
◦ Flip—Switches between the split surfaces.
• Properties—Shows the name of the feature. Click
