Video screen objects consist of a video screen and optional front or rear projector.
Click here for a video tip about this topic (internet access required).
To insert a video screen:
Click the Video Screen tool from the Spotlight tool set.
Click to place the object in the drawing, and click again to set the rotation.
The first time you use the tool in a file, a properties dialog box opens. Set the default properties, and click OK.
The height of the video screen and associated projector(s) depends on several factors.
● The Z value entered from the Object Info palette determines the distance from the active layer plane to the bottom of the screen (including the border).
● When the screen includes legs, the legs are drawn on the active layer plane unless a Floor Height value has been specified. The Floor Height distance shifts the floor, and therefore the legs, by that amount from the layer plane.
● Projector stands are inserted relative to both the Vertical Shift and Floor Height values, allowing stands to be shifted up or down from the screen’s floor as set by the Floor Height value.
The video screen object’s parameters can be edited from the Object Info palette.
