Add a Coincidence Constraint

General

  • Two line segments are coincident when they are on the same line.
  • Two points are coincident when their position is the same.
  • A line segment and a point are coincident when the point is on the line.
  • An arc and a point are coincident when the point is on the arc or on its imaginary extension.
  • If you add a Two-point Line so that you point the start and/or end point from another line or the end point of another line, a coincidence constraint is created automatically between the end point of the line that you add and the clicked line. Similarly, a coincidence constraint is created between the end point of the line and the center of an arc or circle.
    • Coincidence constraint is also automatically created when you add a Polyline if you click its points from other lines or their end points.
    • Coincidence constraint is also automatically created when you add a Rectangle between the first corner point and line of the rectangle.

Add a coincidence constraint in a plane sketch

  1. Select the function Sketch | Constraints | Coincidence.
  2. Select the first line or point.
    • This line or point remains in place unless the other line or point is locked in place with constraints.
  3. Select the second line or point.
    • This line or point will move so that it is coincident with the first line or point.
    • If a line or point is locked in place, the first line or point moves.
  4. Repeat steps 2 to 3 to add new coincidence constraint
  5. Stop adding coincidence constraints
