ADDGROUP in loops

Domagoj Lukinic — Tue, 04 Feb 2025 09:21:38 GMT

Hi all,

I am trying to merge my geometry into one, i found this:
https://community.graphisoft.com/t5/GDL/add-several-GROUPs-without-additional-lines/m-p/274202

However is ti possible to not have an error in the code ("Identical operands in group operation").

I need something like this for my code:

pen 1 material 1 group "object": gosub "Fixed geomety" gosub "Looped geometry" endgroup res = addgroup ("object", "object") placegroup res end:!===================================================== "Fixed geomety": block 1,1,1 return "Looped geometry": for i=1 to 5 addx 1/2 block 1,1/2,1 next i return

I tried to add an empty group but no result, any solutions?

I think the problem is the Addgroup with 2 identical Group Names. Try this:

pen 1 material 1 group "object1" gosub "Fixed geomety" gosub "Looped geometry" endgroup group "object2" gosub "Fixed geomety" gosub "Looped geometry" endgroup res = addgroup ("object1", "object2") placegroup res end:!===================================================== "Fixed geomety": block 1,1,1 return "Looped geometry": for i=1 to 5 addx 1/2 block 1,1/2,1 next i return

I wrote a number that gets 1 added each loop but is converted to a string for the group name. That way there is never a duplicate group name

I use this:

val_a=1 val_b=2 val_z=1 group "mygroup" block val_a,val_b,val_z endgroup mygroup="mygroup" for i= 1 to 3 group "mygroup"+str("%.0m",i) add i*.2,i*.3,i*.1 block val_a,val_b,val_z del 1 endgroup mygroup=addgroup(mygroup,"mygroup"+str("%.0m",i)) killgroup "mygroup"+str("%.0m",i) next i placegroup mygroup killgroup mygroup
