Description
The 2LineCenterLine tool adds a centerline between two Edges.
Aligned centerline between 2 Edges
Usage
- Select 2 Edges in a View. The Edges should be more or less parallel.
- Press the
Add Centerline between 2 Lines button
- A dialog will open where you can specify attributes of the new centerline.
- A centerline will be added between the 2 selected Edges.
If the generated line looks odd or didn't generate at all, you may need to use the option Flip Ends.
To delete a Centerline, select it and use the toolbar button Remove Cosmetic Object.
Editing Centerlines
Any of the centerline command buttons (
Add Centerline to Face(s),
Add Centerline between 2 Lines,
Add Centerline between 2 Points)
can be used to edit any centerline.
- Select a centerline.
- Press any centerline command button.
- A dialog will open where you can change attributes of the centerline.

- Vertical: Forces a centerline vertical
- Horizontal: Forces a centerline horizontal
- Aligned: Follows the general direction of the Edge for 2 Edge centerline
- Shift Horiz: Moves the centerline left or right of its normal position
- Shift Vert: Moves the centerline up or down from its normal position
- Rotate: Rotates the centerline around its center (degrees. + counterclockwise, - clockwise)
- Extend: Makes the centerline longer by this amount
- Color: Color of centerline

Flip Ends
The centerline between 2 lines is drawn between the midpoints (m0 and m1) of the lines that connects the endpoints of the selected lines (p0 and p1), see the sketch. Depending on the point order there are 2 possibilities to draw the connecting lines. The option Flip Ends flips the way the connecting lines are drawn.
