Two-dimensional drawing creating method for personal computer, involves automatically producing and displaying projection lines from all references e.g. vertices, hidden-, visible edges, center lines, thread representations and slopes

摘要

The method involves automatically producing and displaying projection lines (a, b, c) from all corresponding references e.g. vertices, hidden and visible edges, center lines, thread representations, shaped units, slopes, penetrations, and denominations, from geometrical data of CAD software, during construction of the drawing. A three-dimensional model is automatically estimated and displayed in the software based on the drawing.
