The information in this article applies to:
I am working on a duplex and I have created the first unit. Rather than redraw the whole thing, I would now like to copy this unit and make a mirror image of it. How can I do this?
While it isn't possible to group-select objects on multiple floors of your plan, you can do so using the Edit Area tools.
Once a plan is selected, copying and reflecting it takes only a few clicks.
Select CAD> Lines> Draw Line from the menu, then click and drag a line to represent the axis that you will reflect the plan across. This line can be thought of as the mirror that will reflect the plan.
Select Edit> Edit Area> Edit Area(All Floors) from the menu, then click and drag a rectangular Edit Area marquee around the entire plan.
If you simply want to create a copy of a plan that is reverse, instead of create a duplex scenario, as described above, use the Tools> Reverse Plan option.
