There is nearly no reason at all to not use it, but if you are like me, a bit lazy
And the drawings basically have 8 P spaces with an area for basic info about the drawing
then it is more easy and handy to use a viewport i think, in a drawing based on my template, i fill in all the basic info 1 time, finish.
I have different standard info in different layers i can choose from in the P Space's viewport
All the pages have an area for spesific info about that page, and now comes the lazy part
, i dont need to use Block Edit, i can change directly in M Space
And i will never even dream about inserting a Block in all this 8 P Spaces everytime, to get spesific attribute values for each page
But, and it is a very very big but, i cant use the info from the Block's to make a "Drawing list" and send together with the drawings, luckily i dont need to, in the kind of projects i normally work with, maybe that is one of the reasons ??
