Coincident Constraint

Available in TurboCAD LTE Pro / DoubleCAD Pro only


Makes a vertex lie on another vertex, or on another object.

  1. Start with two lines. Activate the Coincident constraint and select the vertex you want to constrain.
  2. Select the line which you want the vertex to lie on. . . . the two vertices will meet.
  3. This constraint is similar when using arcs and circles. Start with a line and a circle, and constrain the line endpoint to the arc endpoint.
  4. If you constrain the vertex to the arc itself . . . . . . the line joins the arc at the tangent point.
