Tangent Constraint (GCTANGENT on page 838) Constrains two curves to
maintain a point of tangency to each other or their extensions.
Horizontal Constraint (GCHORIZONTAL on page 831) Causes lines or pairs
of points to lie parallel to the X axis of the current coordinate system.
Vertical Constraint (GCVERTICAL on page 839) Causes lines or pairs of points
to lie parallel to the Y axis of the current coordinate system.
Colinear Constraint (GCCOLLINEAR on page 827) Causes two or more line
segments to lie along the same line.
Concentric Constraint (
GCCONCENTRIC on page 828) Constrains two arcs,
circles, or ellipses to the same center point.
Smooth Constraint (GCSMOOTH on page 835) Constrains a spline to be
contiguous and maintain G2 continuity with another spline, line, arc, or
polyline.
Symmetric Constraint (
GCSYMMETRIC on page 836) Causes selected objects
to become symmetrically constrained about a selected line.
Equal Constraint (
GCEQUAL on page 829) Resizes selected arcs and circles
to the same radius, or selected lines to the same length.
Fix Constraint (GCFIX on page 830) Locks points and curves in position.
Constraint Parameters
Aligned Constraint (
BCPARAMETER on page 217) Constrains the length of
a line or the distance between two lines, a point on an object and a line, or
two points on different objects.
Horizontal Constraint (
BCPARAMETER on page 217) Constrains the X
distance of a line or between two points on different objects. Valid objects
include lines and polyline segments.
Vertical Constraint (
BCPARAMETER on page 217) Constrains the Y distance
of a line or between two points on different objects. Valid objects include lines
and polyline segments.
Angular Constraint (
BCPARAMETER on page 217) Constrains the angle
between two lines or polyline segments. It is similar to an angular dimension.
Radial Constraint (BCPARAMETER on page 217) Constrains the radius of a
circle, arc, or polyarc segment.
Diameter Constraint (BCPARAMETER on page 217) Constrains the diameter
of a circle, arc, or polyarc segment.
