PurposeThe purpose of this paper is to obtain the reasonable dimensioning for each part and a full-dimension model of assembly dimensions.Design/methodology/approachThe relational path graph of assembly dimension, the shortest-path spanning tree of functional dimension and a revised spanning tree are established in this paper.FindingsThe proposed method can obtain reasonable dimensioning of parts and establishment of dimension model in an assembly.Originality/valueThe proposed method can easily realise by computer and be more suitable to automatic dimensioning and establishment of dimension model of parts.

The dimensioning is a time-consuming job in engineering drawing. So, it introduced an automatic dimensioning method to improve the efficiency of drawing dimensioning. Firstly, it used the functions which provided by Pro/Engineer to extract the parts dimension information from part’s feature. Then, in order to avoid the overlap in dimensioning, it stratified the dimensioning zones. Finally, it constructed a hash function to determine the location of each layer. The method has been implemented in an engineering drawing dimensioning system based on Pro/E, and successfully applied to the dimensioning in engineering drawing of CNC gantry milling machine parts.

By using AutoLISP language based on Autocad, the development process of the tray /carton CAD system should focus on software workflow and overall development program. The system uses nodes descript by a relatively polar coordinate, parametric design, the combination of box/carton-type library with box/carton components library, splicing design methods, etc. With the program designed by AutoLISP language, paper box/carton structure parametric drawing can be achieved according to the mathematical model. The system has the input data legality verification, error handling function, output expansion plan, and automatic dimensioning features.
