CATIA Surface Re-limitation and Connection

http://www.cadfamily.com/downinfo/298662.html

The case study for this lesson is Mobile Phone. The focus of this case study is to use the relimitation and connection tools of Generative shape design workbench and dress up the model to achieve the final finished shape.You will be provided with the base surface. While you perform the operations, you will understand the different functionalities of the tools.
ht DASSAULT SYSTEMESDesign Intent Cerate a smooth blended edge at the top edge which varies with respect to thickness of the phone.• Use Variable fillet to achieve the varying blend along the edge. Create a feature groove on the top face of the phone to add the aesthetics.• Trim the tube surface lying on the face to get a groove feature. Create a display screen with the flange at inside to mount the display card.• Trim the top face of the phone at display location using the extruded surface and keep the inner side of the surface which forms the flange. Create a key pad holes on the top face of the phone to incorporate number keys.• Create the key pad profiles in a sketch and project them on the surface. Split the surface using projected curves. Create a smooth blended edge on the lower case of the phone.• Create a blend surface.The design intent is to create the finished part using the base surface. The model should meet the following given design intents.A. Top edge Variable blend B. Feature GroovesC. Display ScreenD. Key Pad holes
Why to Re-limit SurfacesBasic surface geometry designed consists of raw surfaces and construction elements. These wireframes and surfaces do not define the final shape. Operations such as Split and Trim help to convert these raw surfaces into finished geometry.A. Operations are used to produce the finished geometry shape.B. Elements involved in an operation are kept in the history of the operation, but are hidden.When performing operations, keep in mind the following key points:
SplitUse the Split tool to remove unwanted portions of wireframe and surface elements.You can split :A. Wireframe elements. Wireframe elements can be split by points, other wireframe elements, or surfacesB. Surfaces. Surfaces can be split by wireframe elements, or other surfaces
