Table Of Contents
JOIN
Joins the endpoints of linear and curved objects to create a single object.
SPLINE
Creates a smooth curve that passes through or near a set of fit points, or that
is defined by the vertices in a control frame.
SPLINEDIT
Modifies the parameters of a spline or converts a spline-fit polyline to a
spline.
REVERSE
Reverses the vertices of selected lines, polylines, splines, and helixes, which
is useful for linetypes with included text, or wide polylines with differing
beginning and ending widths.
System Variables
GRIPS
Controls the display of grips on selected objects.
PLINECONVERTMODE
Specifies the fit method used in converting splines to polylines.
Modify Helixes
You can use grips or the Properties palette to modify the shape and size of a
helix.
You can use the grips on a helix to change the following properties:
Start point
Base radius
Top radius
Height
Location
When you use a grip to change the base radius of a helix, the top radius scales
to maintain the current ratio. Use the Properties palette to change the base
radius independent of the top radius.
