Mirror

[Pulldown Menu – Construct-Roof > More.. > Mirror Entity(s) or Smartlines > Mirror]

This command lets you mirror a selected roof. After selecting Mirror, you are then prompted for the number of copies (0 or 1) – 0 simply flips the roof about the defined axis, 1 makes an additional copy of the roof. You then select all the roof planes you want to mirror. You can select the planes individually, or by digitizing a window around the roof. You then define the mirror axis by selecting a method on the text submenu.

The following diagram shows the ability to mirror an existing roof about a vertical line.

The mirror axis in this example was defined by 2-points. Also, 1 copy was requested.

Note that you can define the mirror axis in a variety of ways, so consider this and use the prompts as a guide as to what do – read the prompts.
