|
|
;; wcs1

(entity:set-color wcs1 6)
|
|
;; ()
|
|
; Define a solid block.
|
|
(define block1
|
|

|
|
;; block1
|
|
; Set a color for block 1.
|
|
(entity:set-color block1 3)
|
|
;; ()
|
|
; Define a second working coordinate system.

(define wcs2 (wcs (position 15 0 0)
|
|
|
(position 20 0 0) (position 0 20 0)))
|
|
;; wcs2
|
|
; OUTPUT WCS1 and Block1
|
|
|
; Set the specified WCS to be the active WCS.
|
|
(wcs:set-active wcs2)
|
|
;; ()
|
|
; Define another solid block in the specified WCS.
|
|
(define block2
|
|
|
(solid:block (position 0 0 0)
|
|
|
(position 10 10 10)))
|
