Add a Parallel Constraint

General

  • A parallel constraint can be given between two lines (segments) or between a segment and the lines of the central cross.
  • A distance constraint between two lines, in a way, includes the parallel constraint, because it turns the lines in the same direction.
  • If you add a line locked in the horizontal or vertical direction, the line automatically gets a parallel constraint with the horizontal or vertical axis of the sketch's center cross.
  • If you add a line using the E key to select its direction, the line automatically gets a parallel constraint with the line that you used as a reference.
  • In sketch geometry, the symbol for parallel constraint is .
    • You can use the F9 key to show and hide the symbols of the constraints.

Add a parallel constraint in a plane sketch

  1. Select Sketch | Constraints | Add parallel constraint.
  2. Select the first line.
    • This line will remain in place unless the second line to be clicked is locked in its direction with constraints.
  3. Select the second line.
    • This line moves so that it is parallel with the first line.
    • If the direction of the line is locked with constraints, then the first line moves.
  4. Repeat steps 2 and 3 to add new parallel constraints
  5. Stop adding parallel constraints
    • Select another function or
    • press the V key or
    • press the Esc key or
    • click the middle mouse button.

Draw a line parallel to another line

  1. Select a line adding function.
    • Two-Point Line.
    • Polyline.
    • Rectangle.
  2. Click the start point of the line.
  3. Move the cursor over the line parallel to which you want to draw the line.
  4. Press the E key.
    • The line direction is locked.
  5. Click the end point of the line. Continue drawing the sketch according to the function you selected.
    • A parallel constraint is automatically added to the line that served as a reference.
