Closes open curves either with a straight segment or by moving the endpoints to the start point if they are within joining tolerance of one another.
Steps:
-
Select open curves and press Enter
.
-
The number of curves closed by adding segments and the number closed by moving endpoints are reported.

Lines up and adjusts the length of one curve to another based on their bounding boxes.
Steps:
-
Select the curve to align to.
-
Select the curve to change.
-
The curve will be translated and scaled so that its bounding box aligns with that of the first curve.
The curves must be planar, and both of the planes must be parallel to a world construction plane: World Top, World Front, or World Right.
The translation and rescaling is in the world axis directions.

Moves the curve area surrounding a selected point smoothly relative to the distance from selected point.
Editing is done by moving the selected point. This location on the curve is moved, and the move is smoothly tapered off with increasing distance along the curve from this point.
Use this command to fine-tune curves with many control points.
The command takes over the moving of the control points so that the curve stays smooth. This is difficult on curves that are very dense. The falloff distance is adjustable, allowing the changes made to the curve to be more or less local.
Steps:
-
Select a curve.
-
Pick a point on the curve.
-
Pick a point to move to.
-
Press Enter
to end the command.
Notes
-
The selection point snaps to the closest edit point.
-
Corresponding control points of the curve/surface are moved.
Options
Distance
The distance, in model units, along the curve from the editing point over which the strength of the editing falls off smoothly.
Copy
FixEnds
Keeps the position of the curve ends fixed.
No
If the Distance setting is larger than the distance to one or both ends of the curve, the end of the curve will be allowed to move.
Yes
If the Distance setting is larger than the distance to one or both ends of the curve, the end of the curve will not be allowed to move.
All control points are moved as they would be according to the normal falloff except the end control points. This can lead to an abrupt change in the curve near the end on dense curves.
