Automated dimensioning method of part drawing based on feature association
After 2D part drawing is generated by 3D model,there are many problems such as complicated dimensioning in multiple views and non-standard dimensioning.In order to ensure the integrity of dimensioning of part drawing,an automated dimensioning method of part drawing based on feature association was proposed.Firstly,the parametric modeling method of the feature package was established to analyze the feature correlation.Secondly,an association mechanism of"modified feature-feature association-dimension"was created to obtain the feature dimensions and combined with the dimension completeness processing method to complete the automatic dimensioning of multi-view parts drawing.The algorithm was seamlessly integrated into the Creo software platform to develop an automated dimensioning system for part diagrams.Finally,the effectiveness and feasibility of the proposed method were verified by example testing in Creo platform.
