Open the context menu of the 3D object, choose 3D Effects - Geometry tab.

## Geometry

Define the shape properties for the selected 3D object.

### Rounded edges

Enter the amount by which you want to round the corners of the selected 3D object.

### Scaled depth

Enter the amount by which to increase or decrease the area of the front side of the selected 3D object.

### Rotation angle

Enter the angle in degrees to rotate the selected 3D rotation object.

### α‘αα¦α αα

Enter the extrusion depth for the selected 3D object. This option is not valid for 3D rotation objects.

## Segments

You can change the number of segments that are used to draw a 3D rotation object.

### α°αα ααααα’α£αα

Enter the number of horizontal segments to use in the selected 3D rotation object.

### ααα α’ααααα£α α

Enter the number of vertical segments to use in the selected 3D rotation object

## Normals

Allows you to modify the rendering style of the 3D surface.

### Object-Specific

Renders the 3D surface according to the shape of the object. For example, a circular shape is rendered with a spherical surface.

Object-Specific

### Flat

Renders the 3D surface as polygons.

Flat

### Spherical

Renders a smooth 3D surface.

Spherical

### Invert Normals

Inverts the light source.

### Double-Sided

Closes the shape of a 3D object that was created by extruding a freeform line (Convert - To 3D).

### Convert to 3-D

Use this icon to convert a selected 2D object to a 3D object. You can also select several 2D objects and convert them to one single 3D object. To convert a group of 2D objects to 3D, you must first ungroup the selected objects.
