Hatching - new viewport Shading mode or "Custom"

Right now user have many problems to realize Technical drawing with standards as Hatching

en.wikipedia.org/wiki/Technical_drawing

Eg.:

• imagine object on object in object, etc. then perpendicular camera positioning in ortographic mode set as top, sides, etc. to save right engineering graphic with dimensions, etc.
• any of this object need different hatching, eg. other line thickness, angles, also object need a conture, board frame, etc.

• my idea is eg. to have option to show or hide material, where 1st materials can be hidden an 2nd material show in outliner (now materials not have this option), then we can build layers where user manipulate material to render.

• noo... it's not so easy create material for hatching as link upper showing, soo many difficulties around (eg. art line)

• but why Hatching - new viewport Shading mode or "Custom"? Coz this custom can select 'special group' of views, more like profiles where materials can be maybe Override or assigned to the group.

• this still require to give option to render and save image what user see on viewport including solid mode, xray, etc.
