Parallel shift in bodies

I am a beginner with Shapr3D and ask for support.
I have designed a body, which also corresponds in dimensions and structures to what I need. Unfortunately, I can not open up in self-study, how I can now easily tilt this in its entirety or move in itself. That means the lower surface remains at the place and the upper is shifted easily, so that seen from the side a parallelogram develops and all other forms go along.
I hope I have described it understandably!
Thank you!
