Deform - Curve to Curve Options

To open the Deform PropertyManager with Curve to Curve options:

1. Click Deform on the Features toolbar, or click Insert > Features > Deform.
2. In the PropertyManager, under Deform Type, select Curve to curve.

Example: Deform - Curve to Curve

Example: Deform - Curve to Curve Using Multiple Sets of Curves and Edges

If the target curve is a face or surface edge, you can match the deform model's initial edges using position continuity (a sharp transition) or tangency (smooth transition).

Example of Deform Position Continuity

Position continuity at joining boundary results in sharp edges. Select None for Match under Shape Options.

Example of Deform Tangent Continuity

Tangency continuity at joining boundary results in smooth transition. Select Surface tangent for Match under Shape Options.

The PropertyManager options to control Curve to curve deform features are described below. See Deform - Curve to Curve Examples for more curve to curve deform examples.

Deform Curves

	Initial Curves	Sets the initial curves of the deform feature. Select one or more connected curves or edges as a set. These can be single curves, or sets of contiguous edges or curves.
	Target Curves	Sets the target curves of the deform feature. Select one or more connected curves or edges as a set. These can be single curves, or sets of contiguous edges or curves.
	Set[n]	Allows you to add , remove , and cycle through sets for modification. The curves can be part of a model (edges or section curves) or separate sketches.
	Show preview	Previews results using wire frame (cleared) or shaded (selected) views. To improve performance with large and complex models, do not select this option until you have made all your selections.

Deform Region

You can use the options Fixed Curves/Edges/Faces , Bodies to be deformed , and Additional faces to be deformed in any combination, dependent on the geometry of the model and the desired results. If the selected options conflict, the last entity selected overrides any previous, contradictory selected entity. For example, if you first specified a face to deform and then specified the same face as fixed, the face would be fixed.

	Fixed edges	Prevents selected curves, edges, or faces from moving. Select the fixed edges and additional faces to deform in the graphics area. If Fixed edges is cleared, you can select only bodies.
	Uniform	Attempts to maintain characteristics of the original shape during the deform operation. Uniform can help resolve certain curve to curve deform operations that produce shapes with sharp characteristics. Example: Deform - Curve to Curve with Uniform Selected and Cleared
	Fixed Curves/Edges/Faces	Prevents the selected curves, edges, and faces from deforming and moving. Example: Deform - Curve to Curve with Fixed Edges If the Initial Curves are within the closed contour, the deformation is confined to the contour. If the Initial Curves are outside the closed contour, no point inside the contour is deformed.
	Additional faces to be deformed	Allows you to add specific faces to deform. If no faces are selected, the entire body is affected. Example: Deform - Curve to Curve with Additional Faces to be Deformed If the Initial Curves are sketch curves (not face or surface edges), you must select Bodies to be deformed or Additional faces to be deformed .
	If you select a fixed edge , or a body , the whole body deforms. If you select a face for Additional faces to be deformed without fixing edges, the deform is limited to the selected face.
	Deform radius	(Available when Fixed edges is cleared and Uniform is selected.) Creates a bending-like deformation, using the Deform radius value to determine the region affected by the deform. The region affected is calculated by sweeping a radial-shaped base along the initial curves using the Deform radius value. Example: Deform - Curve to Curve Deform Radius
	Bodies to be deformed	Deforms bodies. Use this option when the Initial Curves are not part of a solid face or surface (sketch curves), or if you want to deform multiple bodies. Example: Deform - Curve to Curve Bodies to be Deformed If you have a multibody part, you can add Bodies to be deformed after you specify the initial body. Only the selected bodies are deformed.

Shape Options

	Stiffness	Controls the rigidity of the deform shape in the deformation process. You can combine any stiffness level with the options under Deform Region. The effects of stiffness are generally more noticeable when you use Fixed Curves/Edges/Faces . Example: Deform - Curve to Curve Shape Stiffness Levels There are three levels of stiffness: Stiffness - Minimum Least amount of rigidity. Stiffness - Medium Medium amount of rigidity. Stiffness - Maximum Largest amount of rigidity.
	Shape accuracy	Controls the surface quality. The default quality can be inadequate in high curvature areas. When you increase the accuracy by moving the slider to the right, you can increase the success rate of the deform feature. Move the slider only as needed because increasing surface accuracy decreases performance. Example: Deform - Curve to Curve Shape Accuracy
	Weight	(Available when Fixed edges is selected and Uniform is cleared.) Controls the degree of influence between two options: Fixed edges Weights the deform towards the entities you specify under Fixed Curves/Edges/Faces . Moving curves Weights the deform towards the edges and curves you specify under Deform Curves as Initial Curves and Target Curves . Example: Deform - Curve to Curve Weight Value
	Maintain boundary	Ensures that boundaries selected for Fixed Curves/Edges/Faces are fixed. Clear Maintain boundary to change the deform region, select additional faces only, or allow the boundaries to move. Example: Deform - Curve to Curve Maintain Boundary
	Additional faces only	(Available when Maintain boundary is cleared). Makes the deform affect only those faces selected for Additional faces to be deformed . Remaining faces are essentially extruded to meet the additional faces. Example: Deform - Curve to Curve Additional Faces Only
	Match	Allows you to match the deform surfaces or faces to the target surface or face edges using these conditions. None No matching condition applied. Surface tangent Matches target edges of faces and surfaces with a smooth transition. Reverse Tangent Changes the direction of the surface or face transition from the target curves or edges. Example: Deform - Curve to Curve Match Options Curve direction Matches Target Curves by mapping Initial Curves to Target Curves using the normals of the Target Curves to shape the deform.
