This might be broken in the master branch.

If you select several blocks and right click, there is a 'Create Hier' action under 'More' that will create a new flowgraph for you.

Hi Andrej, hey Jon,

well, technically, your hier_block2 can also have a io_signature with a variable number of in- and outputs. Haven't tested that in a while (in fact, never with the current scheduler), but in both python and GNU Radio, you'd set the io_signature of your hier_block in the constructor of the same.

However, there's no way to do this in GRC.

Generally, this feels a lot like it would really pay off if you take the time to write a Python hierarchical block – a simple "for" loop could create your 1...N parallel in- and output chains then, and you'd get a lot of flexibility.

Best regards,
Marcus

Hey John,

you could create a hier-block and parametrize it as needed and then drop it 16+ times in your flowgraph. Or you could create a hier block with a variable number of inputs and outputs, but I'm not sure if that's possible.

Best Regards,
Andrej

    I'm working on a flowgraph that has a lot of blocks (sets of identical 
blocks for 16+ channels).

    What's the best way to manage this on-screen in GRC?  Can GRC handle multiple sheets, 
or is there a way to group a bunch of blocks into a "superblock" that shows in 
the flowgraph as a single block?

    Thanks!

    John
