How to use power copy in case of dumb solid(dog house) ?
1. According tooling direction here the attached model consider Y direction :)
2. in tool test they give me a dumb solid and do power copy for it .
I think you mean to be able to position a dumb solid repeatedly throughout a model relative to the tooling direction. To do this you should create a power copy with the minimum of ; a point (typically clip axis origin), a line (main tooling direction), another line (action direction/doghouse opening). With these you can repeatedly place the doghouse geometry throughout a model and then union trim them to the main, this assumes the doghouse is fully intersecting the main body. There are some good tutorials on creating power copies online that should help with that.
