I made a hierarchical block with gnuradio-companion and it saved it  
into .grc\_gnuradio

Next time I open gnuradio-companion, will I have this available as a  
gnuradio block?  
and if yes, where is it, ie, under what section in the right menu?

thanks  
Achilleas

Achilleas,

Yes, you should be able to access your hier\_blocks using the [Custom]  
menu  
on the right menu.

Also, if you are using GNU Radio from master, next, or 3.6.3, there is  
also  
a new button on the toolbar that’s a blue arrow in a near circle. The  
popup  
text reads ‘Reload Blocks’. If you push this, your [Custom] menu will be  
repopulated with any new blocks you’ve created so you no longer have to  
shut down and relaunch GRC.
