The mirroring of Parabuild elements can be carried out in the same way as the mirroring of AutoCAD elements.
The command Mirror is available on the command line and can also be found under the Modify toolbar of AutoCAD.
The method is simple: First select all elements to be mirrored, this may be lines and profiles at the same time, then add 2 points to determine the mirror line.
Plates, profiles, bolts and connections can be mirrored. If a mirrored connection has all of its main elements then these can be edited.
