Scale Objects > Reference Distance - Length (Modify Menu)

This command can be used to scale all kinds of objects in the drawing, that is to change their size. The objects are scaled in such a way that that a specified reference length has a given size. The scaling is proportional, that is, the horizontal and vertical scaling factors are the same. The scaling is performed in relation to the center of a frame surrounding the objects.

This command is particularly useful for matching objects to a particular scale. If the "original" length of at least one length in the drawing is known, then the whole drawing can be brought to the correct size without further calculation.

The objects to be scaled have to be chosen. Click on objects to choose them.

The starting point for the reference distance can be entered by clicking with the mouse anywhere in the drawing.

The end point for the reference distance can be entered by clicking with the mouse anywhere in the drawing.

After entering the reference distance a dialog appears in which the desired length for the previously entered reference distance can be entered. The duplicate function can be turned on locally for this command by enabling the "Duplicate" check box.

Once activated, the duplicate function in this dialog remains active until explicitly deactivated again to simplify repeating operations.
