Loop issue

[JEFMAN]

I'm measuring a sphere with linear scans in a loop V1.
In the loop, I construct a 3D circle using outlier filtering.
I can construct a feature set from scans (SCN1[1..36]), but I'm unable to construct a sphere from circles hits.
I tried to insert a feature set in the loop with CE1.HIT[1..CE1.NUMHITS], and then construct another feature set after the loop with SCN2[1..36], which takes only the first hit of the circle, I tried CE1[1].HIT[1..CE1[1].NUMHITS], nothing works fine...

Any idea ?

Are you looping your linear scan? Meaning, you are doing one scan, then looping that 36 times?

[JEFMAN]

Yes, there's one scan in the loop, and the loop "turns"

[neil.challinor]

I think it's because you can't have an array index within an array index - HIT[1..CE[1].NUMHITS]

Have you tried putting the circle hits into a COP rather than a feature set? You could then just construct your sphere from the COP

I can't select CIRC1[1] in the COP...
If I select CIRC1, I can't add [1] after it in the edit window.

Is there a way (2020 R1 SP13) to see looped features in the list of features ?

It's friday, have a nice weekend, all !!!!!

Maybe there is a connection with what I noticed with loops and scans. Maybe try a variation of this:

I will give it a try, thx !

Just because I pointed it out, doesn't mean I cr_acked the code, This is all bfire85

True...however it did help me with what I wanted to do. Maybe Jef is seeing a variation of what I saw.

Hello Jef, isn't it easier to enable single point in your scans (obviously group them to avoid overflowing in the edit window) and filter them as points? Later construct whatever you want to consruct.

[JEFMAN]

There are more than 10000 hits...
Thx for the input...

****, I quoted instead of commenting. Still too early in Europe :P

I see no issue there :P Just grp them together and maybe change the display diameter of points to 0.2mm or something. Normally in terms of pc resources, the demands should be roughly the same (maybe hide them on second though).

Any time btw, you have helped me more than once in the past

[JEFMAN]

Thx, constadin, I will give it a try...

Have you tried using them seagull brackets ( { } ) instead of the hard brackets ( [ ] )?

...or tried with a variable instead of number?

ASSIGN/X = COUNT
CE1[X].HIT[1..CE1[X].NUMHITS]

[Henniger123]

hi,
1.) in pcDMIS you can only access an array element with square brackets. if you use a different one it's just red.
2.) accessing an array within an array does not seem to work in pcDMIS, no matter how many variables or numbers in between.
-> unfortunately that dont work. (tested)

Ok, thanks Henniger123

good Day,

if you want you can try something like this:
you can write the xyz data to a file and then import the data to a PoindCloud

problem with that:
* for 10k points it takes forever, because he write each point individually into the file
* while writing to the file, the meas values are rounded to the display precision

(circle1 represents the scan)
