Applying Geometric Constraints

Use the GeometricConstraint command to define Geometric Constraints for one or two entities.

To apply Geometric Constraints:

  1. Type GeometricConstraint.
  2. Specify an option:
    • Coincident: Defines a coincident geometric constraint to two points on entities or constrains a point on an entity to an entity.
    • Fix: Causes points on entities and entities to maintain fixed positions.
    • Perpendicular: Causes two Lines or linear PolyLine segments to be perpendicular to each other.
    • Parallel: Causes two Lines or linear PolyLine segments to be parallel to each other.
    • Horizontal: Causes Lines and linear PolyLine segments or pairs of points on entities to be parallel to the X-axis of the current coordinate system.
    • Vertical: Causes Lines and linear PolyLine segments or pairs of points on entities to be parallel to the Y-axis of the current coordinate system.
    • Tangent: Causes one entity to be tangent to another.
    • Smooth: Causes a Spline to constitute fluid geometric continuity with another Spline, Arc, Line, or PolyLine.
    • Collinear: Causes Lines and linear PolyLine segments to be collinear.
    • Concentric: Causes the center points of Arcs, Circles, Ellipses, or elliptical Arcs to coincide.
    • Symmetric: Causes two entities or constraint points on entities to lie symmetrically with respect to a symmetry line.
    • Equal: Constrains Lines to the same length, or Arcs and Circles to the same radius.
  3. The options correspond to the choices provided by individual Geometric Constraints commands.
  4. Follow the command prompts.
  5. The subsequent sequences of the GeometricConstraint command are identical to those of the individual command variants. From the list of options above, click a link to see the command sequences.
