• Surface to modify—Selects a surface to modify.

◦ Pattern/Symmetry/Mirror Feature—Collects a pattern, mirror, pattern recognition, or symmetry recognition feature used to propagate the modify analytic feature to all instances such that the pattern, mirror, or symmetry is maintained.

◦ Extend and intersect—Extends the surfaces of the selected 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 modified.

◦ Bounding edges—Collects edges that act as boundaries for geometry.

◦ Splitting surfaces—Collects the surface to modify when splitting surfaces.

• Clear—Clears the reference collector. Select a new reference.

• 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.

• Cylindrical surface—Radius box. Shows the current radius of the selected cylindrical surface.

• Toroidal surface—Radius 1 box. Shows the radius of revolution. Radius 2 input box. Shows the circle radius of the toroidal surface.

• Conical surface—Angle box. Shows the angle of the cone.

• References—Shows the surface to modify.

• Attachment—Shows options for attaching the modified surface to original geometry.

◦ Attach modified geometry (default)—Reattaches the modified surface to the same solid or quilt where it was originally attached.

◦ Create round/chamfer geometry (default)—Specifies whether to create round or chamfer geometry after the selected surface is modified and attached. Closes gaps created by modifying geometry and recreates rounds or chamfers in the new location. Available when Attach modified geometry is selected.

◦ Store attachment properties—Store the attachment properties to use when you reattach the modified geometry to the model. Available when Attach modified geometry is not selected.

◦ Create side surfaces—Creates surfaces that connect edges to cover the holes left when a surface is modified. Click Details to open the Chain dialog box.

◦ Extend and intersect—Extends the surfaces of the selected modified surface 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.

◦ Propagate to Pattern/Symmetry—Shows a pattern, mirror, pattern recognition, or symmetry recognition feature that is used to propagate the modified surface to all instances such that the pattern, mirror, or symmetry is maintained.

◦ Splitting surfaces—Collects the surface to modify when splitting surfaces.

◦ Flip—Switches between the split surfaces.
