class Direction from IGESGeom inherits IGESEntity
|
|
|
|
---Purpose: defines IGESDirection, Type <123> Form <0>
|
|
-- in package IGESGeom
|
|
-- A direction entity is a non-zero vector in Euclidean 3-space
|
|
-- that is defined by its three components (direction ratios)
|
|
-- with respect to the coordinate axes. If x, y, z are the
|
|
-- direction ratios then (x^2 + y^2 + z^2) > 0
