Sketch tool
Parallel
Constrain two straight sketch lines to remain parallel.
Purpose
Constrain two straight sketch lines to remain parallel.
Where to find it
While editing a sketch, open Constraints and choose Parallel.
Selection
- Tap the reference line and then the line that should align with it.
Steps
- Select two lines.
- Confirm the second line takes the nearest parallel direction and any corners already joined to it stay connected. When the two lines meet, their shared corner remains the rotation pivot.
Options
Result
A Parallel constraint is added between the selected lines. On application, the second line adjusts by the smaller rotation around a shared corner when there is one, and previously joined corners remain connected. The first line stays in place when the other constraints allow it.
Editing
Use Manage Constraints in a relationship constraint panel and delete Parallel to allow independent line angles.
Troubleshooting
The solver cannot make the lines parallel.
The first line stays selected as the reference. Tap a different second line, or remove conflicting angle, fixed, horizontal, vertical, or perpendicular constraints. Tap directly on an edge away from a shared corner to avoid selecting the neighboring line.
