The BackgroundBitmap command manages a background image in the current viewport for tracing or design analysis.
Only one image can be placed in a viewport at a time; placing a second deletes the first.
Background bitmaps are a construction aid, not a part of the scene that will be rendered. To place an image that will render, see the Picture command or viewport Wallpaper.
Background bitmaps are always aligned with the x axis of the construction plane. If you want your bitmap rotated with respect to the construction plan, you must open it in a bitmap editing program and rotate it there, or you can create a rotated construction plane and place the bitmap on it.
Steps
- Pick a location for the first corner.
- Pick a location for the second corner or type a length.
