This utility solves one major problem yet unsolved when working with the Paper Space: It is hard to easily get uniform linetype scale. Setting the PSLTSCALE variable to 1 (ON) forces you to set the LTSCALE variable to 1. This is somehow annoying because you must pop the original LTSCALE value when you switch back to the Model Space.

The LTSCALE Switch is an ARX utility that automatically saves the LTSCALE value when switching from the Model Space to Paper Space, then sets it to 1. It restores the value when you switch back to Model Space even if you quit the editing session within a Paper Space tab. All that in real time .

Suggested solution in 2007-2009: Use the Installation Wizard. The Wizard will registered the LTScale Switch for self loading in the current AutoCAD. If you have many vertical AutoCAD of the same release, use the next solution for each of them.

Alternate solution and previous releases: You need to copy the LTScale_Switch_2007.arx¹ file in one of the AutoCAD search path and load it once. It will be self-loaded next time so you will never need to care about it anymore. A button is dispayed in the status bar to let you toggle from active or sleep mode or set new parameters.

The Ltscale_Switch utility works by itself by using its own parameters. To modify these parameters, right-click the button 'Ltscale_Swith' in the status bar then select Settings.

• Paper space: Default value in layouts means that LTSCALE will be set to this value when you switch to a paper space tab if you don't specify a value for this drawing
• Paper space: Current value in layouts for this drawing means that value won't change for this drawing even if you change the default value.
• Model space: Current value in the Model tab is a value saved in the current drawing
