Concentric (GEOMCONSTRAINT on page 848) Constrains two arcs, circles,
or ellipses to the same center point.
Fix (GEOMCONSTRAINT on page 848) Locks points and curves in position.
Parallel (
GEOMCONSTRAINT on page 848) Causes selected lines to lie parallel
to each other.
Perpendicular (GEOMCONSTRAINT on page 848) Causes selected lines to
lie 90 degrees to one another.
Horizontal (GEOMCONSTRAINT on page 848) Causes lines or pairs of points
to lie parallel to the X axis of the current coordinate system.
Vertical (GEOMCONSTRAINT on page 848) Causes lines or pairs of points to
lie parallel to the Y axis of the current coordinate system.
Tangent (GEOMCONSTRAINT on page 848) Constrains two curves to maintain
a point of tangency to each other or their extensions.
Smooth (GEOMCONSTRAINT on page 848) Constrains a spline to be
contiguous and maintain G2 continuity with another spline, line, arc, or
polyline.
Symmetric (
GEOMCONSTRAINT on page 848) Causes selected objects to
become symmetrically constrained about a selected line.
Equal (GEOMCONSTRAINT on page 848) Resizes selected arcs and circles to
the same radius, or selected lines to the same length.
Show Constraints Displays constraint bars for the selected objects with
geometric constraints applied to them.
Show All Displays all geometric constraints in the drawing.
Hide All Hides all geometric constraints in the current drawing.
Constraint Settings Controls the display of geometric constraints on constraint
bars.
Dimensional Panel
Linear (
BCPARAMETER on page 217) Creates a horizontal or vertical constraint
parameter based on the locations of the extension line origins and the location
of the dimension line similar to the DIMLINEAR command.
Horizontal (
BCPARAMETER on page 217) Creates a horizontal constraint
parameter by picking two constraint points. Valid objects include lines and
polyline segments.
