From Backdrop

Purpose

To generate an RSO by the use of a backdrop view and to store all geometry within this view as marking on the created RSO.

The function will only create the RSO if the backdrop is defined in a principle plane. The plane and the coordinate (keyed in when creating the backdrop view) are used to generate the RSO geometry. If a surface exists and an intersection between the surface and the plane is successful, the RSO is created using this intersection curve. If this is not the case, the RSO limits are generated from the window of the selected backdrop view.

An RSO that is created in a principle planes X and Y, will be limited by the surface and the upper deck. If an RSO named WEATHER exists, this one is used as the upper limit. If it does not exist, then this RSO is created automatically. The function fetches a suitable Z value from the intersection curve between the plane and the surface.

Prerequisites

A view generated as a Backdrop must exist in the current drawing. Backdrops are generated using the function Backdrop in the Tools menu.

Instructions

A Backdrop view shall be indicated and an RSO name shall be given.

Options

Not available.

Result

The created RSO of type Backdrop with marking is stored on the data bank.
