Options Tab

Continuity

G0, G1, G2, G3

(G3 in ICEM Shape Morphing only)

Controls the transition quality between blend and adjacent surfaces for the two connecting edges.

These options are only available if Support is selected

Alignment

Controls the distribution of the control points of the blend surface.

For the modes Edges start/end, All edges and Auto, the start and end tangents can be modified via the manipulator. When using these options, the inner cross tangents are propagated.

As the direction of the cross tangents is fixed when using Standard and Linear, the start and end tangents cannot be modified.

Standard: Connects corresponding points on all blend edges at Side 1 and Side 2 via a line. The direction of this line is projected onto the tangent plane at the specific position of the edge. This projected direction is used as a U tangent of the blend surface at the specific edge point.
Edge continuity cannot be defined.

Alignment: Standard
Edges start/end: Continues existing cross edges of the support at Side 1 and/or Side 2 . The direction of the cross tangents within the specific edge will be spread over the whole edge (with respect to isolines).
Edge continuity can be defined.

Alignment: Edges start/end

Alignment: Edges start/end – distribution of tangents
All edges: Continues all edges of the support crossing the blend edge. The cross tangent directions will be propagated over the edge (with respect to isolines) until a segment border is reached.
Edge continuity cannot be defined.

Alignment: All edges

Alignment: All edges – distribution of tangents
Linear: Continues cross isolines if the edge is adaptable the U or V isoline of the support.
Edge continuity cannot be defined.

Alignment: Linear
Auto: Automatically distributes the cross tangents.
Edge continuity can be defined.

Alignment: Auto

Edge continuity

(G3 in ICEM Shape Morphing only)

Aligns the beginning and end cross tangents at the edges of the blend and adjacent surfaces.

Edge continuity can be defined for Edges start/end and Auto.

Start and end continuity Cleared: The beginning and/or end cross tangents will be aligned coplanar only, i. e. there may be an angle between the cross tangents of the blend and adjacent surfaces.
Start or end continuity Selected: The beginning or end cross tangent of the blend surface will be aligned collinear to the beginning or end cross tangent of the adjacent surfaces.
Start and end continuity Selected: All cross tangents of the blend surface will be aligned collinear to the cross tangents of the adjacent surfaces.

Trim Type

Trims the underlying support surfaces at the connecting edges of the created blend surface.

Creates approximated surfaces.
Creates trimmed surfaces.
