number of beamsegments in value array

[DNU]

Hi all 

For a label linked to a segmented beam I want to chose a segment in the label settings so the label can give the settings from that segment.
Works perfect except for one part; i can't define the value range for how many segments there are in the beam.

Parameters:

    I_segment (integer)

In the Master script;

    I_maxSegments = 0
    For i = 1 to 7 ! 7 is just a random number to prevent crashes
        IF HASKEY(BEAM_SEGMENT_INFO.segments[i].crossSection.startWidth) then
            I_maxSegments = I_maxSegments+1
        ENDIF
    next i
   PRINT I_maxSegments ! this works perfect

In the Parameter script;

    VALUES "I_segment" RANGE[1, I_maxSegments]

Values given in the label settings "1 < = value < = 0"

Any Ideas?

Hi,

BEAM_SEGMENT_INFO is not available in parameter script context, but is in UI context.

parameter script:

for i = 1 to 100 ! a reasonably large number of segments
    put i
next i
values "n" get(nsp) ! range [1, ) doesn't work with ui_infield

UI script:

dim pic[], val[], choice[]
for i = 1 to  vardim1(BEAM_SEGMENT_INFO.segments)
    pic[i] = 0
    choice[i] = str(i, 1, 0)
    val[i] = i
next i

ui_infield{4} "n", 0, 0, 100, 20,
    8, "", 0, 0,
    0, 0, 0, 0,
    pic, choice, val

The 2d script has to handle that the number of segments can decrease below the selected value.

Btw. if you need to label only one of the segments, before label placement you can switch between labeling the whole beam or the segment only by pressing tab when the mouse is on the beam but not on the axis.

Thanks, Péter!

This works perfect.

The reason I can't link the label to the segment is that the label provides other information, such as properties that are either unavailable or not filled in for the segment.
