The Sweep2 command fits a surface through a series of profile curves that define the surface shape and two curves that define the surface edges.
Steps
Select two curves as the rails.
Select cross-section curves in the order in which the surface will pass through them. Select open curves near the same ends. For closed curves, adjust the curve seams.
Reverses the curve direction.
Attempts to align the seam points and directions without intervention.
Moves the seam points to the way they were at the beginning of the command.
Yes - The seam points are always at the knots. You can only move them among the knots.
No - The seam points may leave the knots. You can move them without restriction.
Do not change cross sections - Creates the sweep without altering the cross-section curves.
Rebuild cross sections with ___ control points - before creating the sweep.
Refit cross sections within ___ - Refits the cross-section curves before creating the sweep.
Preserve first cross section - When you are matching edge tangency or curvature, your surface may pull away from your cross-section curves. This option forces the surface to match the first cross-section curve.
Preserve last cross section - When you are matching edge tangency or curvature, your surface may pull away from your cross-section curves. This option forces the surface to match the last cross-section curve..
Maintain height - Removes the association between the height scaling from the width scaling. By default, cross-section curves normally scale in both the height and width dimensions.
Refit rails - Refits the rail curves before creating the sweep.
Continuity is only enabled if the rails are surface edges and the shape curves are non-rational, that is, all control-point weights are 1. Exact arcs and ellipse segments are rational.
Only continuity options that the curve structure (point count and rational/non rational) supports will be available.
Closed sweep - The Closed sweep option creates a closed surface, continuing the surface past the last curve around to the first curve.
This option is only available after you select two cross-section curves.
Add Slash - Adds additional cross-section alignments to control how the surface is created between sections.
