[Therion] therion sketch .th, Use of Grade UISv1_1

[alastair gott]

Hi Therion mailing list,

I'm trying to use the function "grade" in one of our .th files, theres a sketch made of a cave with very little detail, but we think it would be better to include it.

I'm strugging to get the function grade to work, therion is giving me red writing "-- not enough data readings" and stopping the survey from generating, but only when I implement the grade function.

I must be using it incorrectly, but I've tried it between survey and centreline commands too and that isn't working either. this gives red writing "-- invalid value -- centerline"

centerline
    #[omitted] ​
    units length meters​
    units compass clino degrees​
    data normal from to length compass clino​
    extend left​
    grade UISv1_1​
    0 1 1.00 300 0.0​
    1 2 1.00  0.0 0.0​
    2 3 1.00  0.0 0.0​
    3 4 1.00  0.0 0.0​
    4 5 1.00  0.0 0.0​
    endgrade​​
  endcenterline
