A is defined by one of:
radiusdiameterwidthheight
Only one of these values can set for any particular circle. The others
are determined automatically by the first.
The default radius is value of the "circlerad" variable.
A: circle thick rad 120% line thin color gray left 70% from 2mm left of (A.w,A.n) line same from 2mm left of (A.w,A.s) text "height" at (7/8<previous.start,previous.end>,1/2<1st line,2ndline>) line thin color gray from previous text.n up until even with 1st line -> line thin color gray from previous text.s down until even with 2nd line -> X1: line thin color gray down 50% from 2mm below (A.w,A.s) X2: line thin color gray down 50% from 2mm below (A.e,A.s) text "width" at (1/2<X1,X2>,6/8<X1.start,X1.end>) line thin color gray from previous text.w left until even with X1 -> line thin color gray from previous text.e right until even with X2 -> X3: line thin color gray right 70% from 2mm right of (A.e,A.s) X4: line thin color gray right 70% from A.rad above start of X3 text "radius" at (6/8<X4.start,X4.end>,1/2<X3,X4>) line thin color gray from (previous,X3) down 30% <- line thin color gray from (previous text,X4) up 30% <- line thin color gray <-> from A.sw to A.ne line thin color gray from A.ne go 0.5*A.rad ne then 0.25*A.rad east text " diameter" ljust at end of previous line
