Parameters

Propagate

True propagates the sweep to the next edge, false causes the sweep to occur only on the selected edge; to propagate to the next edge, the next edge must be tangent to the current edge

TwistCtrlOption

Twist control option as defined by swTwistControlType_e

KeepTangency

If the sweep section has tangent segments, then True to cause the corresponding surfaces in the resulting sweep to be tangent, false to not

BAdvancedSmoothing

If the sweep section has circular or elliptical arcs, then True to approximate the sections and smooth the surfaces, false to not

StartMatchingType

Tangency type as defined by swTangencyType_e

EndMatchingType

Tangency type as defined by swTangencyType_e

PathAlign

Align path type (see Remarks)

UseFeatScope

True if the feature only affects selected bodies, false if the feature affects all bodies

UseAutoSelect

True if the feature only affects selected bodies, false if the feature affects all bodies

TwistAngle

If TwistCtrlOption set to swTwistControlConstantTwistAlongPath, then specify end twist angle

BMergeSmoothFaces

True to merge smooth faces, false to not

Return Value

Because you are creating a surface, the sections can be open.

Use IModelDocExtension::SelectByID2 to select the profile and sweep curves. The mark for:

• 1 = Profile selection

• 2 = Guide curve selection, if provided

• 4 = Sweep path

The PathAlign argument is available when TwistCtrlOption is set to swTwistControlFollowPath and can take one of these values:

• 0 = None; no correction (default)

• 2 = Direction vector; a plane, planar face, or line defines the path

• 3 = All faces; includes neighboring faces

When UseAutoSelect is false, the user must select the bodies that the feature will affect.
