d the project by drawing internal ponents in Pro/ENGINEER .Compad provided detailed Pro/E NGNEER parts used in its CFcard sleeve design .An initial assembly was used for subsequent configuration proposal . Configurations that passed specifications were printed in real size to serve as a modeling aid for preliminary foam mockups . Eventually one mockup passed the field tests and was used as the basis for the next design phase . The final configuration defined the optimal placement for the ponents . An outer casing tightly packed the ponents , leaving as little space as possible between the ponents and the casing .We started with the Advanced Surface Extension (ASX) module of Pro/ENGNEER 2020i2 , but it soon became clear that to design the bounding surfaces with more freedom , a plete freeform design solution was needed .The dynamic aspect of design and the plex surface transitions (especially in the hand grip area and the transition from sleeve to casing ) required a more flexible and powerful tool. Taking a Test Drive A local reseller offered two solutions : CDRS and ISDX .While CDRS is an industryproven solution for drawing Aclass surfaces ,it is a seperate application that would have forced us to learn to work in an entirely new environment .In addition ,we anticipated that frequently shifting from one application to another , even if well implemented through the 5 ATB , would slow down design process. Coincidentally , a preproduction version of Pro/ENNGNEER 2020 was shipping at the time . This version included a new feature called the style feature . This interactive surface design extension or ISDX arrived just in time . Although still in preproduction ,ISDX had the same stability and roubstness as Pro/ENGNEER Foundation . After a short training period ,Pars pro toto began using ISDX。 we were the first in Europe to apply this feature in an industrial design project . Design time was significantly shortened because changes were reflected immediately in the model . ISDX also helped us draw the intricate curvature continuous curves needed for the plex surface transitions. The clearance between the ponents and the surface envelope was observed at all times to ensure that material thickness was sufficient and tight around the ponents. Concurrent En。
