It's a incredibly Jungle of formats, often just to make only wrong 3D, true 2D perspectives, or to keep a juicy market just for its trust (ex.: Cathia Solidworks 3DCad = Dassault, gunrunner, arms dealer; see Autodesk; Max, Maya). If all that was real, I will take a chain saw, to clear out the place. Is the developers are bad woodcutters? May be... May be. Help Mr Pierre Bézier! Come back again! ... To have very powerful computers to make forests of icebergs? It's not "glop" not "glop" ("pas glop" is a onomatopoeia of Roudoudou, a french strip cartoon, that said in substance: "not terrible; not good; not great; I don't like", it's like a sort of gobbling, glug-glug).

Well, so It must to produce shoddy work, to do DIY, to tinker (Oh lala! English has not the verb "Bricoler" = To make trouble bits and pieces = "Des Bricoles", bits; "du Bricolage", just been thrown together; a bad do-it-yourself).
Ok! I go to make a bit with this jungle, but, not glop, not glop.
