Title: prototype antimatter
Post by: ElpanovEvgeniy on December 27, 2018, 09:05:08 AM
Antimatter - try the commands:
_UNION
_SUBTRACT
_INTERSECT
between copies of this box or other AutoCAD created with the help of commands.

Well it's 3DSOLID - it is just with flipped faces and it acts opposite than real 3DSOLID when modelling operations applied... This sort of thing IMO isn't too helpful when dealing in 3D SPACE - it can just bring problems... Antimatter is empty DWG... You have nothing and when you subtract nothing from nothing or union nothing with nothing or intersect - you should get nothing and not something... If this strange things are improvement to CAD then I am disappointed... When modelling is an issue, there are more important things to be solved than playing with those things... For example, UNION, SUBTRACT and INTERSECT will error when dealing with close to overlapping 3DSOLIDS - inconsistent face-face relationship - Modelling error... :

Or there is also unsolved non uniform scaling of 3DSOLIDS - LISP can only be some sort of support, but not solution - look here :

Anyway for purpose of experimentation this is acceptable, but for practice, work and real appliance this thing can only bring chaos...

Nice that you are well and you posted. Thanks to that and happy New forthcoming 2019 Year to you and your family...
Best wishes to all, M.R.

Thank!

My current project is creating 3dSolid used the entmakex / entmod.

This error seemed ridiculous to me. I decided to share on this forum.

Happy New 2019 Year!  :-)
