Virtual DesignCATIA Reverse Engineering

The use of numerous systems to develop digital products fromphysical prototypes is complex and costly, leading to delays inproduct development. Companies require intuitive environments thatare ergonomic and fully-integrated to ensure their investment pays offquickly.

CATIA Reverse Engineering makes it possible to quickly captureand enhance physical prototype shapes, making the 3D virtual modelthe design reference. I t also provides powerful technologiesembedded within CATIA that allow the easy manipulation of clouds ofpoints or meshes, while quickly transforming them into high-end 3Dsurface shapes.

Key capabilities

Impor t and expor t c louds o fp o i n t s i n v a r i o u s s t a n d a r dformatsThe user can impor t a lmost a l lnative measuring machines? data.Data can be of different types, forexample, meshes, grids, scans,and clouds of points. Imported datacan be of d i f ferent formats, forexample, standard formats (IGES,free ASCII, STL, etc.) or formatsfrom nat ive measuring machinemakers, such as GOM, HYSCAN,KREON, STEINBICHLER, etc. Theuser can preview, scale, trim, orchange the measuring units of theimported data.
