Sweep 2 Rails
Crease splitting enabled
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.
Select connected edges based on the curve continuity of the connection between segments.
Creates a surface that begins or ends at a point. Use this option only at the start or end of the curve series.
Adjust seam options (Closed curves only)
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.
The seam points are always at the knots. You can only move them among the knots.
The seam points may leave the knots. You can move them without restriction.
Select each seam point and move it along the curve to line up all curve seams.
Use the Flip option to make all seam arrows point to the same side.
Press Enter to continue.
Sweep 2 Rail Options dialog box
Creates the sweep without altering the cross-section curves.
Rebuilds the cross-section curve's control points before creating the sweep.
Refits the cross-section curves before creating the sweep.
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.
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.
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.
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.
Sets the continuity for the edge match.
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.
Adds additional cross-section alignments to control how the surface is created between sections.
Fit a surface through profile curves and one edge curve.
The SubDSweep1 command sweeps a shape curve along a rail curve to create a SubD.
The SubDSweep2 command sweeps a shape curve along two rail curves to create a SubD.
Fit a surface through profile curves that define the surface shape.
Fit a surface through a network of crossing curves.
