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.
• You can also use cylindrical and conical surfaces as the other party of the parallel constraint.
• If you add a line locked in the X, Y or Z 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.
• If you give the parallel constraint to a line and a plane surface or a line and a sketch plane, the line will turn parallel to the surface's normal, i.e. "perpendicular to the surface". In other words, the surface direction is the direction of the surface normal.

Add a parallel constraint to a 3D sketch

1. Select 3D Sketch | Constraints | Add parallel constraint or
   • select the context-sensitive function Constraints> Parallel
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. Click another line, surface, sketch plane, or auxiliary plane.
   • 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.
   • If the selected plane, sketch plane, or surface is locked (such as a surface selected from another part), then the first line will move.
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.
