Add a Perpendicular Constraint

General

• A perpendicular constraint can be set between two lines (segments).
• Drawing rectangles adds the necessary perpendicular constraints between lines.
• In sketch geometry, the symbol for perpendicular constraint is .
  • You can use the F9 key to show and hide the symbols of the constraints.

Add a perpendicular constraint in a plane sketch

1. Select Sketch | Constraints | Add perpendicular 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 perpendicular 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 perpendicular constraints
5. Stop adding perpendicular constraints
   • Select another function or
   • press the V key or
   • press the Esc key or
   • click the middle mouse button.

Draw a line in a perpendicular direction against 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 to which you want to draw a line in a perpendicular direction.
4. Press the T 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 Perpendicular constraint is automatically added to the line that served as a reference.
