METHOD FOR GENERATING THREE DIMENSIONAL STAIR OBJECTS IN COMPUTER AIDED DESIGN DRAWINGS
摘要
Embodiments of the invention provide a method for generating a three dimensional representation of a staircase in a computer aided design drawing. Generally, embodiments of the invention allow a user to create a three dimensional stair object with an arbitrary tread shape and with an arbitrary overlap between any two adjacent treads. A user creates or specifies line work elements in a two dimensional plan view to represent aspects the desired staircase, and a computer aided design application generates a three dimensional stair object from this information. Once generated, a three dimensional stair object may be manipulated using a variety of user selectable grips, simplifying both the design process and work required to modify a three dimensional stair object included in a CAD drawing.
