class XYZAxisPresentation from DsgPrs
---Purpose: A framework for displaying the axes of an XYZ trihedron.

is
Add(myclass;
aPresentation: Presentation from Prs3d;
anLineAspect : LineAspect from Prs3d;
aDir : Dir from gp;
aVal : Real from Standard;
aText : CString from Standard;
aPfirst : Pnt from gp;
aPlast : Pnt from gp);
---Purpose: Draws each axis of a trihedron displayed in the
-- presentation aPresentation and with lines shown by
-- the values of aLineAspect. Each axis is defined by:
-- - the first and last points aPfirst and aPlast
-- - the direction aDir and
-- - the value aVal which provides a value for length.
-- The value for length is provided so that the trihedron
-- can vary in length relative to the scale of shape display.
-- Each axis will be identified as X, Y, or Z by the text aText.
