from 3d to 2d "clean" and "light": how?

[reggio]

hi guys, I often need to "simplify" 3d drawings that I receive to use them in 2d studies.

I usually limit myself to changing the view from assonometry to front or in the view "plate" that I need, but this does not free me from the "weight" of the model neither from the infinite lines and points of the 3 axis that I do not use, nor from the difficulty of ironing or making changes;

If then I need 2 or 3 views in 2d, I make copy of the whole model for 2 or 3 times increasing to unmistress weight and difficulty.
I therefore wondered if there was no method that could provide me with the "flat and clean copy" of the 3 main views, free from lines and points and other of the 3 axis: what of you is possible? How do you explain to me?

put yourself in the view you want to generate and use the flatshot command (or geompiatta in Italian). you will be created a 2d "clean" block of sight

hello and thank you, unfortunately both with _flatshot and geompiatta do not get that a little part of what I expected.
both with and without tangential edges get this:
Am I wrong?

 

[Tristan]

Are they all solid?

...the question...
They all look like blocks, how do I verify it if everything is usual?

I attach the file

the zip is empty. . .
