Simple Question:

I'm trying to create a group that includes all points whose ptnum is greater than 0. Thus:



However, I get this instead:



I've tried a number of different variations, with no luck.

What would be the correct expression to get every point with a ptnum greater than 0 to be in my group?

Thank you!

* = everything
^n = except n.

this syntax works also with attributes and groups handling

since @ptnum is not an attribute you can't use ad-hoc group syntax (if it was an attribute, they you would still need to make sure there are no spaces in your expression)

but for what you are doing you can use Group Expression SOP with your expression as you have it

Thank you Andr & Tamte! The background info helps me understand what's going on under the hood.
