Layout Sketch + Paths, Belts, Blocks

I created a new assembly, clicked "layout" from thecommandmanager, sketched several entities, and created severalblocks. I then selected an arc entity of a block (intended tobe acam), went into tools - sketch tools - and "makepath" wasunavailable!  I also noticed belt/chain wasunavailable....

is this a setting on my end, fault in process, or a lackinthe software?

I also noticed in layout ellipses and polygons areunavailable... Ihad to create a new part, sketch the entities, makeblocks, andthen insert them into the layout...

Has anyone made blocks and then made paths or belts/chainsfrom theblocks in an assembly layout?

thanks for your time; it is appreciated!!!SolidworksAssemblies
