Abstract:

Engineering drawing is an important basis for production, so it’s necessary to
optimize the 3D engineering drawings to meet enterprises’ requirements. An adaptive optimization
principle based on model templates and engineering drawings templates is given by using the
correlation between the model and the drawings. Principles of template customization are put
forward; the methods with ordinary and special customization are presented to lay the foundation
for the subsequent optimization. Several key technologies of adaptive optimization are discussed,
including view positioning, scale matching, dimension positioning and part-list optimization. And
finally a satisfying engineering drawing of large complex assembly is obtained.

Key words: engineering drawing, template customization, view positioning, scale matching;
dimension positioning
