Change the ViewPort Scale

[sundaram1087]

Hi 

I am writing the script to create the drawings. In that i had an requirement for updating the VP Scale by script

I can able to change the VP Scale by manually but am not able to update it by command line method.  Please refer the following images for your reference

I have created the Custom Scales  like "SR-S0" in view port (Ref-Image1)

Initially it was set to SR-SO and then based on requirement i need to change that to SR-S1

For Change the scale i used the command "cannoscale". By using that command it scale get changed but the view port not updated. For that i need click the option that "Click to Synchronize" to update the view scale

Please suggest your thoughts how to overcome this issue

Thanks & Regards

I have the advantage of working in metric so this part is easy the viewport has a property "Customscale".

For metric customscale= 4 is 1:250 ie 1000/250 = 4.

So shoud be able to set the customscale to a imperial value. Make sure viewport is not locked as will will not work again lock is a property.
