I want to draw a control block diagram, but cannot find the shape
described above, standing for the addition of two signals.

Something like this, but with a "×" in it:

Can anyone tell me which category should I pick up? Thanks.


That is not in the sample png, but it is easy to create. Just draw a circle
and add two diagonal lines to it.
