Close/Open
One of the following options displays, depending on whether the selected
spline is open or closed. An open spline has two endpoints, while a closed
spline forms a loop.
Close Closes an open spline by defining the last point to be coincident with
the first. By default, closed splines are periodic, maintaining curvature
continuity (C2) along the entire curve.
Open Opens a closed spline by removing the final curve segment between
the first and last points specified when the spline was originally created.
Join
Combines a selected spline with other splines, lines, polylines, and arcs at
coincident endpoints to form a larger spline. Objects are joined with kinks at
the points where they are joined (C0 continuity).
Fit Data
Edits fit point data using the following options:
Enter a fit data option [
Add (page 1028)/Close (page 1029)/Delete (page 1029)/Kink
(page 1029)/Move (page 1029)/Purge (page 1029)/Tangents (page 1029)/toLerance (page
1030)/
eXit (page 1030)] <eXit>:
Add
Adds fit points to the spline.
After selecting a fit point, specify a new fit point to be added to the spline in
the direction of the next fit point, which is automatically highlighted.
If you select the last fit point on an open spline, the new fit point is added to
the end of the spline.
If you select the first fit point on an open spline, you have the option of
specifying whether the new fit point is added before or after the first point.
