CST2013: Create an Analytical Face

Modeling: ShapesFaces and AperturesAnalytical Face

In this dialog box you may specify an analytical face by defining the analytical functions for x(u,v), y(u,v), z(u,v), and the range for the parameter u, and v. The construction will always be performed in the currently active coordinate system.

Each analytical face will be assigned to a particular material in which all shapes will share the same material properties and colors.

The new analytical face is also associated to a certain component and is identified by a unique name within this component. The shape can be addressed by this name for subsequent editing operations.

As soon as the shape is defined it will appear in the main plot window and beneath the associated component in the navigation tree

Name

Specify the unique name for the analytical face.

X(u,v), Y(u,v), Z(u,v)

Specify a valid function dependent on the parameters u, and v for defining the coordinates of the analytical face in global coordinates. Please note that these entries only appear when the global coordinate system is currently active.

U(u,v), V(u,v), W(u,v)

Specify a  valid function dependent on the parameters u, and v for defining the coordinates of the analytical face in local coordinates. Please note that these entries only appear when a local coordinate system is currently active

Min(u/v), Max(u/v)

Specify a valid parameter range for the parameters u and v.

Component

Choose a new component from the select list. You can also create a new component by typing the name of the new component.

Material

Select the material to which this shape will be assigned from the list of previously defined materials or create a new material by selecting [New Material...]. You can also load a material from the material library by selecting [Load from Material Library...].

OK

Press this button to finally create the analytical face.

Preview

Press this button to create a preview image of the analytical face. This option is very useful to check the settings before you actually create the shape.

Cancel

Closes this dialog box without performing any further action.

Example

A hyperbolic paraboloid (saddle surface):

X: u

Y: v

Z: 0.25 *(u^2-v^2)

u range: -4 to 4

v range: -4 to 4
