In Tekla Structures, when you copy or move objects, you can mirror them through a plane that is perpendicular to the work plane and passes through a line you specify.

Note that Tekla Structures cannot create mirrored copies of object properties. For example, the Copy > Mirror command does not fully mirror objects if they include components with asymmetrically positioned parts, or reinforcement objects with asymmetric properties such as spacing.

Mirror objects in a model

Use this method to copy and mirror, or move and mirror objects in a model.

  1. Select the objects you want to copy or move.
  2. Activate the mirroring command.

    • To copy and mirror, go to the Edit tab and click Copy > Mirror.

      The Copy - Mirror dialog opens.

    • To move and mirror, go to the Edit tab and click Move > Mirror.

      The Move - Mirror dialog opens.

  3. Pick the start point of the mirroring plane, or enter its coordinates and angle.
  4. Pick the end point of the mirroring plane, or enter its coordinates and angle.

    The first picked point (X0, Y0) is the origin, and the second picked point calculates the angle around the origin.

    If the dialog is open but the command is no longer active, click the Pick... button to re-activate the command.

  5. Click Copy or Move.
