Creating 2D Centerlines in NX Drafting

You can create centerlines between parallel curves or through points on a technical drawing by using the “2d Centerline” command in the NX Drafting.

To activate command:

• Menu => Insert => Centerline => 2d Centerline
• Home Ribbon Bar => Annotation Group => Centerline drop-down arrow => 2D Centerline

To create centerline between straight lines:

1. Start “2D Centerline” command
2. Set the type of the centerline as “From Curves” on the first tab of the command dialog box.
3. Select the first straight curve
4. Select the second straight curve
5. Click “Ok” to finish the command

Note: This command creates centerlines on the center of two parallel lines. If the straight lines are not parallel do not use this command. It does not create a centerline on the middle angle of the lines. The image shows the angle differences between the centerline and two edges.

To create centerline through points:

1. Start “By Points” command
2. Set the type of the centerline as “From Curves” on the first tab of the command dialog box.
3. Select the first point
4. Select the second point
5. Click “Ok” to finish the command
