This has been bugging me for a while, especially when working with files (importing, Blocks,…) that have different units (eg. meters+centimeters) and also for drawing plans in different scales (i am aware of layout linetypes, but personally I need to see things correctly in Modelspace already)
the ability to scale linetypes per layer and as an override per object would be very very helpful.
I am mainly doing Architectrual work, but I think any discipline can benefit from this function.
