Hi, newbee here,
built sill plates (each board is a group)
sometimes when i 3 click to move I find that other boards have moved
chasing my tail, any help or tutorial suggestion would be greatly appreciated, thanks Mike
I suspect this is your issue.
Single click to select a group or component to move.
Triple click does all sorts of things.
3 clicks (finally selected the board I was after)
You have nested components and must work your way into the nest to reach what you want. Take a look at the outliner window.
Share the model. Looks like you have excessive nesting going on.
