Blocks in corridor

[Anonymous]

Hi,
My question is this is option to make sub-assemblies from block? I know there is option to make it from poliline.
And 2nd question is how to put something in right place (right distance from center of assembly).

For example I've got poliline (this red on left picture) and I use ConditionalHorizontalTarget to find poliline but how to put something like this flag (on the red circle) in right direction?

Should I make line to this poliline on the target (yellow) and in style choose to hide this yellow sub-assembly?
Please help me 🙂 And sorry for my english

Firstly, you never need to apologize for your English skills. The fact that you know more than one language puts you far ahead of me and most Americans. 

No, you cannot use a block as a subassembly. You should use Subassembly Composer to create the shape.

Regarding the ConditionalHorizontalTarget, just place, at the outside end of the conditional subassy, the subassembly you want added if the condition is met. If it needs to look like the sample you provided, you will need to use Subassembly Composer.
