LeWitt'scube constructioncan not be used in this way. An alternativeto this modifiedcavalierperspective would be the followingaxonometry,which is also called pure, unshortenedisometry. Usingthe cavalierperspectivein technicaldrawing, y o u u s u a l l ys h o r t e nt h e l e n g t ho f t h e s i d e sb y h a l f . LeWitt'scube constructionis only an approximation to this principle.

Thesecognitivereconstructable relationships would have been a further reason for the selectionof one of the severaldifferenttypes of isometricdisplay. The relationships betweenthe individualplanesare the following: E a c hp l a n ei n t h e d i s p l a yh a s d o t s a r i a n g e di n a g r i d pattern.Each plane has an equivalentelsewherein the cube with the same patternof dots. The relation betweenthese planesis quite simplythat the other planeequivalentto it, takes its place in the cube, when tilted 180 degrees.This does not apply to the squarein the middle,exceptwhen you see it as a mirroredimage of itselftilted 180 degreesor as a planethat consistsof two rectangulartriangles,one of it being a repetitionof the other tilted 180 degrees. LeWitt uses constructionlines to derive from one of the basicforms of bodies- the cube - more complicatedstructuresby subtraction.This is quite like some of the things done in technicaldrawingthrough certainsubtractingconstructionmethods..The.derivationsare achievedby dividinginto halfsffiquarters the sidesof the 'basic cube' and connectingthe r e s u l t i n gd i v i d i n gp o i n t sb y l i n e s .T h e f o l l o w i n gl i n e s , connectingcorner pointsof the grid pattern,are amb i g u o u sa n d c a n b e u n d e r s t o o dt h r e e - d i m e n s i o n a l l y only by taking into accountthe context of particular body constructions: - - - dimensionally ambiguouslinesgoingout from cornerpointsof the grid pattern Some of the linesthat can be connectedin more than o n e w a y i n t h e t h r e ed i m e n s i o n sa r e l o s i n gt h e i r a m biguousmeaningin the cavalierperspective.LeWitt only constructsthe three sidesof a body visiblefrom 'viewing one a n g l e.' 7 H e c o u l d d r a w t h e l i n e st h a t a r e not visible,as well.

(15) The selection of colours is based on a closed system of combinations of four colours with each other, which is shown in Four basic colors and all their combinations, in Cat. of exhib. La Grande Parade, Stedelijk Museum, Amsterdam, 1984, p. 211 a.o. Within this system hue-variants are possible by using more of totally f .e. Jqur,gr-fjve parts of one colour than of the one, two or three other colours. LeWitt fi8Eftbifthis closed colour-system with a linear syntax which constitutes an open system. LeWitt uses different manners to denote the colours inlheWorking Drawings. For an explanation of one of these manners see T. DREHER,Beuys zu Ehren, in: Das Kunstwerkd XXXIX, 1986, in print.
