Draws a circle by defining its centerpoint and the preferred radius.
How to use
1. Click the Preferred Circle icon or choose the Tools > Curves > Circle > Circle: center, radius command.
2. The program console prompts Local axes origin.
3. Place the centerpoint of the circle either by clicking and dragging in 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 curve 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 of the circle or by typing the radius value in the console. Hold the mouse button down after the click to interactively draw the circle.
If you press the Shift key, there is no need to hold the mouse button down to draw the circle: just click to define the preferred radius.
Options
Start angle
To change sweep of the arc.
Views. Choose the Edit mode. Click the 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 pressing Enter. The value can range from 0 to 360 degrees.
End angle
To change sweep of the arc.
Views. Choose the Edit mode. Click the 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 and pressing Enter. The value can range from 0 to 360 degrees.
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 (exact) or non-weighted (approximated).
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 in the section 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.
Points
To determine the number of control points of the circle in case you have chosen Non-weighted in the above section.
Modeling Tool panel. Set the value either by moving the slider or by typing it in the data field and pressing Enter (remember: the more the control points, the more approximated the circle).
