Places and manipulates a background image in the current viewport
for tracing or design analysis.
Steps:
-
Click an option.
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.
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 PictureFrame
command or the ViewportProperties command, Wallpaper
option.
Options

-
Pick a reference point on the construction plane that matches the bitmap reference point.

Yes
The background bitmap displays in shades of gray.
No
The background bitmap displays in color.
Saves the bitmap to an external file.
If Yes, the image will be filtered to estimate pixel values to try to create a smoother image.
Moves the background image.
-
Pick a base point.
-
Pick a point to move to.
Places a background image in the current viewport.
Note: Placing a new background bitmap replaces the current bitmap.
-
Pick the first corner.
-
Pick the second corner, or type a length.
Updates the stored bitmap if the file has changed.
Removes the background image from the current viewport.
Scales the background image in the current viewport.
-
Pick the scale origin.
