Description
Creates a centerline geometry associated with two selected lines or polyline segments.
Note: Centerlines are drawing reference entities to indicate axes of symmetry.
Method
When applying a centerline to the intersection of two lines, the location of the picked points determines the direction of the centerline.
- First segment selected.
- Second segment selected.
- Resulting centerline.
The lines and polyline segments can be selected inside blocks and in drawing view viewports. You can pick two segments of the same polyline.
Note: The centerline is associative, so when one or both lines are moved, the centerline repositions itself.
Note: Centerlines can be edited through grips. It can be moved and lengthened by dragging the grips. The CENTERRESET command can be used to reset the centerline.
