Interactive baseline

The interactive baseline allows you to manually define the baseline, even per track if needed. It is useful when LS is not able to make a nice baseline on your profiles.


For interactive baseline, you need to define several segments on the profile, which should be interpreted as baseline. Between each segment points, the baseline would be interpoled, using the chosen spline type.



  • btnBsAdd Add one or more new baseline segment(s). After activating the function by clicking on the button:

    1. Click where the baseline segment should start on the profile.

    2. Click again where it should end.

    3. Other segments can be added by repeating this process

    4. Moving the mouse cursor outside the Profiles viewer will stop the creation function.

  • btnBsRemove Remove the selected baseline segment in the list.

  • btnBsClear Remove all baseline segments.

  • btnDisplaySegments Display or hide the baseline segments.

  • btnApply When modifying the interactive baseline for a specific track, the baseline segments can be applied to all tracks of the plate.

Baseline segments list

The list display where the segments start (X1) and where they stop (X2). The values are always in Rf.

Spline type

The baseline between each point is interpoled using a spline algorithm:

  • Cubic: needs at least 3 segments.

  • Linear: needs at least 1 segment.
