... the model space was designed to draw the object in its real size, then if one wants to break the head face as well...
I allow myself to do the creepy, to make understand a concept that is very unknown.
the model space was not "thought for". the model space is the space of autocad, since it was born.
is the paper space that has been added after, as ease, as comfort. but the scale problem remains the same.
You have to see that joy when some big astrologer of the drawing to the cad, draws a metro station (civil works I mean) in mm. you find yourself with a 3000-long panel, where you go to the layout and misuri, it becomes 300 because eventually uses a 2:1 print scale to print it at 50... and you have to insert that design into a georeferentiated paper (which is normally 1unita=1m... )
or when you iron an element in the model and (thought) that is all right. sin that the element came out of the layout window and no longer enters the table... then edit to the layout, windows and away.
Unfortunately, the speech you do is valid when you only deal with yourself.
Instead the way is varied and many do not want a dwg that recalls another dwg (xref), designed 1:1 with layout layout layout layout layout, because they are quite ignorant of the program to just open a drawing measure and print.
you know how many, with a 1:50 drawing in the layout they call you to say:
♪
The design is wrong... I mix the cover is wide 21, I mix the 1m long element (which should be 2cm in scale at 50) instead I measure 1.. but that you combined!" and you have to explain to him that when you mix an item that is in the autocad model you return the model measurement, while if you minuri a layout element returns the layout measurement, which you have to trust and that the design is correct in the printing stage.. .
They don't want to know. . .
I'm gonna run out, and now I'm gonna grab a couple of beers. prosit
