When inserting and copying/pasting a 干式系统板 component it is possible to switch between active edges/snap points:
TAB - cursor moves clockwise
Shift+TAB - cursor moves anticlockwise
If an edge is active on a 干式系统板 component being inserted (cursor in the centre of the edge) - then 3 points are activated: 1 in the centre and 2 in corners.
If individual points are active on a 干式系统板 component being inserted, the program switches between edge points of the component grid and snaps onto the grid points of other 干式系统板 components.
Copying of several 干式系统板 components: the program switches between subsequent snap points of 干式系统板 components that make up the block being copied.
Moving a 干式系统板 component: the active edge or point is selected based on the "grab" location of the component, and changing with the "Tab" key is disabled.
