All the videos I have seen show the use of the wall tools. Framing, joists, and rafters are more of a DIY project. Make a stud, floor joist, or rafter and use the gripper to drag out a copy and place. The gripper will constrain the axis direction, especially when working in isometric view. There are other tools such as "Linear Array" and "Path duplicate" for moving multiple boards quickly.
If you work in feet/inches set the resolution pretty tight, say 1/64". This will help prevent round up/down errors when doing copy and move multiple boards, the compound error will add up.
I'm including a framing project I did a while back. I still have some work to do but it has been pushed to the back burner for now.
