You’re already familiar with this new tool, conceptually at least, if you’ve used the 3rd party applications COINS Section Box or Xrev View Box. Just select elements and click the button to generate a 3D view with a section box cropped around those elements.
You may not want to give up those other tools just yet because they may offer more control of the resulting view than this tool does. It carries out the action with your default 3D view so if you didn’t want to mess that one up you need to remember to save it before you use it. It is easy and fast, you decide if you agree.
