Advanced Surface DesignA CATIA Shape Design and Styling Solutions Product

Highlights

Industry-Proven Productivity – Leading-Edge Technologies

• Offers precise design tools tocreate complex surfaces usingvarious constraints

• Lets the user easily create filletsbetween two surfacic (surface,face or skin) elements withconstant radius

• Enables users to create internal,sharp corners by manuallyselecting a subset ofautomatically selected edges forfillet definition

• Trims supports for filletedelements

• Linearly blends constant radiusfillets created on different edges

• Lets the user easily createcomplex variable fillets alongedges of a skin

• Reorders fillet sizes to bringtogether multiple radii

• Allows designers to modifyswept surfaces by altering someof the generating elements

• Offers strong associativitybetween surface and soliddesign

• Provides direct surface data fordownstream tasks such as 2Ddetailing and numerical controlprogramming

• Can parameterize surface parentcurves and constant laws

• Creates and analyzes drafts on2D contours and surfaces, evenfor very complex parts

• Includes analysis functions toverify "mold-ability"

• Reduces the need for physicalmock-ups to handle surfacecurvature and reflect continuity

Advanced Surface Design includes toolsto create drafts on 2D contours, faces,surfaces and skins, even for verycomplex parts. Analysis capabilitiesincluded in the product facilitate verifica-tion of "mold-ability" of the part.

Automatic Filleting and Rounding...Automatic filleting between two surfaceelements eliminates the need for time-consuming manual trimming of geom-etry. Advanced Surface Design canround the sharp edges on one or bothsupport elements avoiding possibleerrors if done manually.

Surface Creation... With AdvancedSurface Design, designers can formhighly accurate swept surfaces whilecontrolling the tangency to adjacentsurfaces. The section to be swept can beany plane shape such as a straight line,arc, conic, free-form curve or series ofjoined curves. The user can automati-cally create varying radius cylindrical orconic fillets between surfaces, faces andskin elements. With cylindrical filletsbetween ruled surfaces, the system cangenerate five-axis millable parts thatassure a continuous tool path whenmoving from one surface to another.

Modification of Surfaces... The designof complex surfaces is mainly an iterativeprocess during which the designercreates a surface, analyzes its charac-teristics and modifies the design toimprove its quality. The constructionhistory associated with surface genera-tion provides the designer with a verypowerful tool. This history is the linkbetween a surface and the elements thatwere used in its construction. AdvancedSurface Design allows the user to easilymodify a surface by going back andaltering some of the generating ele-ments such as curves, variational lawsand adjacent surfaces.

Surface/Solids Integration... Either ofthe CATIA solids products (Solid Mock-Up or Exact Solids) can complement theAdvanced Surface Design product.Being fully integrated, the surfacing toolscan take advantage of design param-eterization and the solids environment.For example, when a designer modifies aparameterized surface, the system canautomatically update the related solid.Users have the ease of use and visual-ization benefits of solids with thecomplex shape handling ability ofsurfaces.

Investment Protection... Designers canreuse and manipulate “as is” modelsfrom CATIA Version 3 in the advancedSurface Design product.
