CATIA Reverse Engineering

The use of numerous systems to develop digital products from physicalprototypes is complex and costly, leading to delays in productdevelopment. Companies require intuitive environments that areergonomic and fully-integrated to ensure their investment pays offquickly.

CATIA Reverse Engineering makes it possible to quickly capture andenhance physical prototype shapes, making the 3D virtual model thedesign reference. It also provides powerful technologies embeddedwithin CATIA that allow the easy manipulation of clouds of points ormeshes, while quickly transforming them into high-end 3D surfaceshapes.

• Reduce project costs andstreamline designiterations

Key capabilities

Import and export clouds of pointsin various standard formats The user can import almost all nativemeasuring machines? data. Data canbe of different types, for example,meshes, grids, scans, and clouds ofpoints. Imported data can be ofdifferent formats, for example,standard formats (IGES, free ASCII,STL, etc.) or formats from nativemeasuring machine makers, such asGOM, HYSCAN, KREON,STEINBICHLER, etc. The user canpreview, scale, trim, or change themeasuring units of the imported data.

Robust alignment and deviationchecking for control processes CATIA Reverse Engineeringprovides several robust strategies forthe alignment of digitized data withother digitized data or in relation toCAD models. It also providesextensive and associative diagnosiscommands such as: Deviationchecking between digitized data,

surfaces or curves Annotations andreporting on deviation checkingConnect checker between surfacesallows the visualization of eventualdeviations during the joining ofseveral surfaces in passage,tangency and curvature Thanks tothese alignment capabilities anddiagnosis commands, CATIAReverse Engineering covers controlprocesses such as: AlignmentControl between digitized dataDeviation Control between a rebuiltCAD model and the master digitizedmodel Control of an object asmanufactured and the CAD mock-upas designed

Smart and advanced tools tomanipulate clouds of points andmeshes Thanks to several 2D and 3Dcomputation methods, the user cancreate watertight meshes that can be:Used in the CATIA V6 DMU product,rendering, etc. Directly manufactured

in CATIA V6 manufacturing productExported in STL format for rapidprototyping machines CATIAReverse Engineering also provides aset of smart and advanced editiontools to manage and improve cloudsof points and meshes such as:Working on sub-areas Removing,cleaning, filtering, smoothing, holefilling and shape improvement Meshsegmentation in pertinent surfacedomains

Wireframe creation CATIA Reverse Engineeringprovides tools to create wireframe(scans/polylines or curves) and curvenetworks: Planar sections Interactivecreation of free curves or curves onsupport Curve creation by smoothingscans/polylines Curve projectionCurve network managementAutomatic characteristic linesdetection

Surface creation CATIA Reverse Engineering allowseasy surface creation (mechanicalshapes or free-form shapes) fromdigitized data. Several approaches torecover surfaces depending of theshape's type are available: Forfree-form shapes by fitting on adomain delimited by N-sides 3Dcurves networks and constraints onboundaries For mechanical shapesby identifying and preserving editablefeatures (plane, cylinder, sphere,cone) Recovering virtual sharp edgesby extending and trimming primarysurfaces For sweeping surfacesusing a loft command Automaticsurface creation from a meshaccording to a given accuracy

Polygon modeler for virtual claymodeling CATIA Reverse Engineeringprovides a set of intuitive polygonalmodeling and sculpting tools thatwork like clay modeling. It isparticularly well suited to shapedesigns when surfacing becomescomplex.

Rapid prototyping CATIA Reverse Engineering alsocovers the rapid prototyping processthrough surfaces and solidtessellation capabilities to getwatertight meshes.
