Reference Distances

Scale Objects > Reference Distances (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 target length. 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 size. If the "desired" 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.

1.	Choose objects

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

2.	Enter starting point of line 1

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

3.	Enter end point of line 1

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

4.	Enter starting point of line 2

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

5.	Enter end point of line 2

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