GENERATIVE SHAPE DESIGN WORKBENCH.
CATIA TUTORIAL: GENERATION OF
PARAMETRICALLY DEFINED BASIC
SURFACES
1) In this tutorial you will practice how to build
basic surfaces from two dimensional
elements. You will use the Generative Shape
Design and the Sketcher workbenches
2) Start by launching the CATIA Software. The
PRODUCT design workbench appears as a
default interface. On the top is the
Workbenches toolbar. Access the
Generative Shape Design Workbench by: a)
clicking once the indicated icon or b) Find
the command in the Start pull-down menu.
3) Once you enter the Generative Shape Design
you can see how the Structure Three has
changed to Part.1; it also contains the basic
structure: a) Reference planes b) Part Body
and c) Open body.1. The part design host
surface and solid components, as well as
all two dimensional entities.
4) Around the screen you can find the
Toolbars for construction of three
dimentional entities: points, lines, planes,
splines.
CREATING A PLANE:
5) Start by clicking once in the plane icon. A
dialog box called plane definition appears
with the options and parameters. From the
to select offset from plane option and
select the YZ plane. The selected plane
highlights indicating that the selection has
been made.
6) A plane appears both in the screen and the
the Structure Tree. Type in the distance you
want the new plane to be located.
7) Once all parameters have been defined
click apply to update the screen. If you are
satisfied click OK. The dialog box closes
and the plane in defined.
8) If the parameters are incorrect you can
make the necessary adjustments and see
the changes by clicking Apply before
clicking OK
9) Once the plane is defined it can be
redefined by: a) double click on the plane;
and b) double click in the corresponding
name in the Structure Tree. The same
definition dialog box appears.
10) You will build three-dimensional basic
surfaces by using two-dimensional
sketches defined in the Sketcher
Workbench.
