After that object properties (arrow size, text height, ...) does not depend on intelligent scale.
if I am correct this is referring to the “intelligent” scaling of hatch patterns and text size according to the view at the time they are inserted. The whole point of intelligent scaling for text and hatch patterns is so that you can print them out at specific sizes and they should be related to the scale of the viewport not the zoom factor at the time of creating.
In AutoCAD this is called annotative text and is a relatively new feature over the past couple years. The whole point of it is to be able to create text that will print out at a standard size no matter what the paper size is with the scale of the viewport.
For example architects typically like the text to be an eighth of an inch high when printed. That means that you need to create text in model space at an eighth of an inch multiplied by whatever the scale factor is on the viewport that it will end up in. TC implementation of this simply uses the zoom factor at the time of creating text which is a completely arbitrary number and can change.
There is absolutely no consistency with the text size created which is the whole point of having intelligent scaling.
