| Abstract: | An approach to the feature identification and counting of the hole features for the Die & Mould engineering drawing was proposed to address automatic datum dimensioning.The combination notes of the functional semantic and counting results of the hole features can be given at the same time in the drawing,based on the feature identification.The proposed approach has been designed and implemented by utilizing the programming language,VisualLISP provided by AutoCAD.The practical datum dimensioning cases were gi... |
