The 3D ACIS® Modeler (ACIS) is Spatial’s prominent 3D solid modeling engine. 3D InterOp is a CAD data translation framework (Interoperability)

From DocR19

Every ENTITY has an is function associated with it. The following set of functions in acistype.hxx are used to determine if an ENTITY is a topological type, and upper case geometrical type or an attribute.

; body?
;
; create a solid block
(define block1 (solid:block (position 0 0 0)(position 15 15 15)))
;
; determine if the solid block is a body
(body? block1)
;; #t
