# CATIA SURFACE MODELLING PDF

Curvature continuity means that at each point of each surface along the common boundary has the same radius of curvature. Which is only possible with high-class finish and good forms. This is the reason why in design industries Class A surface are given more importance. Understanding Class A surfaces: 1. The flow of the highlight lines — The lines should form a uniform family of lines.

What is thickness of surfaces? Infinitely less 2. What is hybrid modeling? Is it possible to set default co lour for surface? Yes, we can set default colors for surface. The purpose of federation is to regroup several elements making up joined surface or curve. This is especially useful when modifying linked geometry to avoid re specifying all the input elements. What is default value for distance objectives in join command? How does the nearest in project command will affect?

Is it possible to perform a shell operation on a sphere? Yes, we can shell a sphere. What is healing of geometry? What are distance objectives in healing? What is smoothing of curves? This task shows how to smooth a curve, i. Maximum deviation may be in distance or angles is the allowed deviation between the initial curve and smoothed curve. If this option is checked then it automatically deletes the vertices, thus reducing its numbers of segments. List the different commands available to create surfaces?

Checking this button allows the system to automatically reduce the number of elements faces or edges in the resulting join whenever possible. G0 propagate: — The tolerance corresponds to the merging distance value.

G1 propagate: — The tolerance value corresponds to the angular threshold value. What is the file save extension of surface? CAT part is the file save extension of a surface.

## CATIA V5 SURFACE MODELING DESIGN

Surface Design Surface Modeling The basic tasks you will perform in the Wireframe and Surface workbench are mainly the creation of wireframe and surface geometry you will use to build your part design. When creating a geometric element, you often need to select other elements as inputs. When selecting a sketch as the input element, some restrictions apply, depending on the feature you are creating. You should avoid selecting self-intersecting sketches as well as sketches containing heterogeneous elements such as a curve and a point for example.
