Offset Line Snap
Use this snap command to calculate a point based on an offset from a station along the entire length of a line or an arc. Station zero is the end of the line closest to where it was picked. From station zero, looking down the line, positive offsets are to the right and negative offsets are to the left of the line. If the line has a sloping elevation, the Z value is interpolated from the station used.
Note: You can use this option to select a specific position along an arc by making the offset distance zero.
Offset Line Snap can be used in these controls:
