How to move elements on tekla

Hello everyone

I wanted to know on tekla how you could move elements on the OX axis, on the left side because right is ok.

I also wanted to know how to take elements from the library and integrate them into the drawing, should I also create my own library?

Have a good day and thank you in advance for your answers

Hello

 

Have you browsed the Tekla support site? 

I don't know anything about this software.
