Working of COOR{3}

runxel — Mon, 08 Jan 2018 15:24:18 GMT

Why does always just the last COOR{3} statement take effect?
How can I cancel that behaviour?

CPRISM_ ...
COOR{3} ...

! Later:
CPRISM_ ...
COOR{3} ...

In this shortened example the first COOR{3} doesn't seem to take place at all / gets overridden by the second one.

Isn't that when you need to use the BODY 1 after the COOR?
I may be wrong - I haven't tested it.

i.e.

CPRISM_ ... 
COOR{3} ... 
BODY 1

! Later: 
CPRISM_ ... 
COOR{3} ...
BODY 1

Wow, thanks Barry.
I saw it – and didn't even bother trying, because it's clearly stated, that "BODY 1" is deprecated...

But! – it works. So I'm gonna keep it. Thanks again!

I think it means that COOR{1} and COOR{2} are deprecated and replaced with COOR{3}
There is no need to define the VERTs now and it is not very clear but I think the BODY 1 is still needed to define the end of the form (body) that the COOR works on.

Yes, but have a look for yourself here.
It clearly states

j1: closed body (deprecated)

And it is not really verbose in everything else; that the BODY 1 is needed is never stated anywhere.
So thanks again for pointing me to the right direction

Ah that is the 'status' in the BODY command.
j1 & j2 are deprecated.
The BODY command itself still works.

Just not clear in the examples of COOR, COOR{2} & COOR{3} that you still need to use BODY.

Actually when I first answered you I was looking in an old GDL book - version 6.5 that only has COOR.
This is the last physical GDL manual and I still have it sitting on my desk as I find it easier than the PDFs when I want to find something quickly.
I just assumed it would be the same for COOR{2} and COOR{3} - lucky guess maybe?
