Sphere

Adds a sphere to the scene.

 

How to use

1. Click the Sphere icon or choose the Tools > Primitives > Sphere command.

 

2. The program console prompts Local axes origin.

 

3. Position the sphere either by clicking and dragging any view (release the mouse button to confirm placement) or by typing its XYZ coordinates in the console. Values must be separated by a comma, i.e. 1,2,3, and confirmed by pressing Enter. If you press Enter without typing any value, the axes origin of the sphere will be placed in correspondence with the XYZ origin.

 

4. The program console prompts Radius.

 

5. Define the preferred radius by either clicking and dragging the Radius point hotSpot or by typing the radius value in the console. Hold the mouse button down after the click to interactively draw the circle.

 

Options

 

Longitude start angle

To change sweep of the arc.

Views. Choose the Edit mode. Click the Longitude start point hotSpot and drag it. Release the mouse button when you reach the desired angle.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and press Enter. The value can range from 0 to 360 degrees.

 

Longitude end angle

To change sweep of the arc.

Views. Choose the Edit mode. Click the Longitude end point hotSpot and drag it. Release the mouse button when you reach the desired angle.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter. The value can range from 0 to 360 degrees.

 

Latitude top

To cut the sphere at the top.

Views. Choose the Edit mode. Click the Latitude top hotSpot and drag it. Release the mouse button when you reach the desired angle.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter. The value can range from -90° to 90°.

 

Latitude bottom

To cut the sphere at the bottom.

Views. Choose the Edit mode. Click the Latitude bottom hotSpot and drag it. Release the mouse button when you reach the desired angle.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter. The value can range from -90° to 90°.

 

Radius

To change the preferred radius.

Views. Choose the Edit mode. Click the Radius point hotSpot and drag it. Release the mouse button when you reach the desired radius.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.

 

Arc type

To specify whether the circle must be weighted or not.

Modeling Tool panel. Switch the chosen radio button on. You have the following options: Weighted and Non-weighted. If you choose the first option, the number of control points is automatically defined. With the second option you can set the number of control points along longitude and latitude as explained in the sections below.

 

Note: In general, you could use Weighted if you do not plan to modify the original shape and Non-weighted if you want to edit it. Although a non-weighted sphere is an approximation (a very close one) of an exact sphere, it offers more flexibility when you need to deform it.

 

Points along longitude

To determine the number of control points along longitude of the sphere in case you have chosen Non-weighted in the Arc type section.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.

 

Points along latitude

To determine the number of control points along latitude of the sphere in case you have chosen Non-weighted in the Arc type section.

Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter.
