NOTE In order to create and use photometric lights, a unit other than Generic

must be specified from the list of options. If Insertion Scale is set to Unitless, a

warning message is displayed informing you that the rendered output might not

be as expected.

Insertion Scale

Controls the unit of measurement for blocks and drawings that are inserted

into the current drawing. A block or a drawing that is created with units that

are different from the units specified with this option is scaled when inserted.

The insertion scale is the ratio of the units used in the source block or drawing

and the units used in the target drawing. Select Unitless to insert the block

without scaling it to match the specified units.

NOTE

In the Application Preferences dialog box, Units & Guides tab, the Source

Content Units and Target Drawing Units settings are used when, either in the

source block or the target drawing, Insertion Scale is set to Unitless.
