MOUS_ICO Menu: Noise > Barriers
nco: Select a barrier (defined in Novapoint Noise)
For general information about barriers in Novapoint Noise, see Barriers.
In the menu, the items above the line are functions for barriers in general. For the items under the line, an object selection is required. This can be done before the function is called, or afterward. The selection will be filtered so it only changes barriers. Objects in the selection that are not barriers are not affected.
