Hello. I created my first beam family and place it as a structural framing which is a simple concrete beam with an "L" shape. I need to creat a "wall" made out od these beams with a 2 meter section each and when I first place it there is no issue but later when I copy and paste them using the Revit tools, the dimension change and doesn't move nor aligned properly, as well as the witness lines seem to be chosen randomly. I believe there might be a problem with the reference planes the moment I created the rfa but I am unsure. I post the rfa for reference.
Thank you.
