Need LDPC help

[Johann Eisner]

Hi all,

Recently I dove into LDPC and need some help.
Questions I have:

1. Can I use primitives in patterns?
2. Can I select more then one primitive and copy/paste/duplicate them?
3. Can I group a primitives and triangles and copy/paste/duplicate them?
4. Can I use submodels in patterns?

For example, I am creating the pattern for the laserrelector sticker from set 10266.
It has a repetative pattern of dots.
I made one dot with disc primitives and filled the gaps with triangles.
Now I want to use that dot as many times as needed, create the rows and copy them.

Attached is my work so far.

Thanks.

1. Yes ( When using disc prim then always use a ndis prim to) 
2. No
3. I don't know 
4. Yes
