T-Values from a SCN Set

dph51
Ex. SCN1 (either a constructed set or scan feature)

T-Value Calculation and reporting of Max and Min Values.

No generic points needed.

No Loop.

No previous Dimensioning.

Create a T-Value array, find maxval and minval, and get the maxpnt and minpnt.


ASSIGN/TVAL=0

ASSIGN/TVAL=DOT((SCN1.HIT[1..SCN1.NUMHITS].XYZ-SCN1.HIT[[COLOR=#ff0000]1..SCN1.NUMHITS[/COLOR] ].TXYZ),SCN1.HIT[[/COLOR]1..SCN1.NUMHITS].TIJK)

ASSIGN/MAXVAL=MAXINDEX(TVAL)

ASSIGN/MINVAL=MININDEX(TVAL)

ASSIGN/MAXPNT=GETTEXT("REFERENCE ID",MAXVAL,{SCN1})

ASSIGN/MINPNT=GETTEXT("REFERENCE ID",MINVAL,{SCN1})


Then dimension any two points x,y,z,t
Say LOC1 PNT1 & LOC2 PNT2

Highlight LOC1 and replace it with MAXTVAL
Highlight PNT1 and replace it with MAXPNT

Highlight LOC2 and replace it with MINTVAL
Highlight PNT2 and replace it with MINPNT


That's it.

    I've tried to use your code, as it solves an out put problem I have, but I can't get a result.
    Placing the pointer over the lines just gets a 0 or shows the line of code with no result.
    I've checked the code over & over, may be I've missed something as my eyes are starting to blur. PLN4 =FEAT/PLANE,RECT

    As you can see I'm working with an old version of DMIS and have never got [1..SCN1.NUMHITS] to work.
    Hopefully a set of expert eyes can see what's wrong. ( I know I'm working in foreign Rolling eyes )
    I thought it could be a language translation thing, I'm working in French as well, but turning back to English changes nothing.

    Any help would be greatly appreciated.
    I'd like to add a big thanks to all here for their help although I don't come here offtenBlush
