Calculation of Dimension Chain through AUTOCAD Secondary Development Technique Based on Dimension Tracking Method
Based on the principle of the dimension chain, this paper studies the dimension chain mathematical model and chooses a reasonable method for calculation of the dimension chain, establishing a model of the calculation of dimension chain margin of computer aided analysis and calculation. On AutoCAD platform, we developed the dimension chain calculation analysis software through secondary development by VBA, and applied the technology to dimension chain margin check. This significant saves the time spent in the process of manually calculating the dimension chain.
