expression error

[cloudfx]

Hi all,

I have a grid with various size of faces on it.

Its extruded and I added connectivity sop to create class attribute.

I made group with partition sop with this expression :

piece_$CLASS

and it worked, it showed me :

43 primitives in piece_1

78 primitives in piece_2

23 primitives in piece_3

21 primitives in piece_4

....

and I was trying to delete some groups with delete sop and copy sop looping.

'"piece_" + stamp("../copy2","copynum",0)'

It keep saying that it is invalid group name.

Thanks,

-j

try

piece_`stamp("../copy2","copynum",0)`

[cloudfx]

try

piece_`stamp("../copy2","copynum",0)`

Thanks, its working but why?

Last time, I did similar work, and it worked that way. with something like this:

'"_" + stamp("../copy2","copynum",0)'

Can you explain why so that I can understand clear?

Thanks!

actually you can use them both

but if you are entering a string value into a string parameter it is not necessary to put it in ""

your first expression should work also, but maybe you entered ' (to the left from Enter) instead of ` (under the Escape)

Thanks for reply!!

is it possible to select by the groups that I made? like from group "piece_45" to "piece_78"?

I have those bunch of groups, right? but I want to select specific groups and make a big group out of the group so that I can delete some.

you can procedurally manipulate groups by Group Geometry SOP

look at Combine tab, here you can merge, intersect, subtract groups

in the Edit tab there are other operations, like convert, rename and delete

or manually with the select tool, you have grouplist and a few operations in the operation controls bar above the viewport
