Use of Triad

Would someone take pity on a new solidworks for makers user and help me understand how to use the triad to define axis's in solidworks connect, shop floor app for both the stock and tool. I have fought this issue for over a week with no success.  My tool usually ends up sideways. I draw simple flat design with through pockets and define them on top plane, but when they are imported into shop floor they usually come up wrong with respect to axis's. I have spent a considerable amount of time on youtube in search of helpful video's, but most offer little insight to such problems. Any help would be appreciated...coming from a background in Fusion 360 which I understood, but pricing has forced me to Solidworks for makers......
