### 10.1.1. Parts - New - Select Predef (2D)

This window lets you select the Predef you want to use for the 2D Part you are creating.

Click one of the six buttons at the top of this window to select your Predef :

• Box

This predef is a box with its axes parallel to the X and Y axes.

Origin

X and Y coordinates of the lower corner of the box.

Box Dimensions

The dimensions of the box (DX, DY).

• Circle

This predef is a circle.

Section

The section you want to generate (Whole, Half or Quarter). This should match any symmetry planes you have defined for your model.

Solid or Hollow

A solid or a hollow cylinder.

If you choose a hollow cylinder, you will have to specify inner and outer radii for the cylinder.

Origin

The X and Y coordinates for the center of your circle.

Rotation

The rotation (in degrees) of your circle relative to the X-axis.

• Ogive

This predef is an ogive with its axes parallel to the X and Y axes.

Section

The section you want to generate (Whole or Half). This should match any symmetry planes you have defined for your model.

Solid or Hollow

Choose either a solid or hollow ogive.

If you choose a hollow ogive, you will have to specify inner and outer radii for the ogive.

Origin

The X and Y coordinates for the center of your ogive.

Principal Direction

The direction of the principal axis for your ogive.

• Wedge

This predef is a wedge with its lower edge lying on the X-axis. The wedge angle is automatically set by Autodyn.

This predef is useful for running 1D cylindrical or spherical symmetric problems in 2D.

The minimum radius of the wedge (this cannot be zero).

The maximum radius of the wedge.

• Rhombus

This predef is a rhombus with its diagonals parallel to the X and Y axes.

Section

The section you want to generate (Whole, Half or Quarter). This should match any symmetry planes you have defined for your model.

Origin

The X and Y coordinates for the center of your rhombus.

Width

The width of the rhombus.

Height

The height of the rhombus.

Coordinates X1, Y1

Coordinates of the first point of the quad.

Coordinates X2, Y2

Coordinates of the second point of the quad.

Coordinates X3, Y3

Coordinates of the third point of the quad.

Coordinates X4, Y4

Coordinates of the fourth point of the quad.
