> [!TIP]
> ### Requirements
> 
> No selection is required to launch the command.

1. Click some points in the scene.
2. You can force parameters (**Center** C, **Axis** N, **Radius** R**, Angle** A**, Height** H) by clicking on the locks:
  1. Enter the XYZ coordinates in the edit controls or click on the icon ![AddPoint.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/AddPoint.svg) to click a [point](/v1/docs/cyclone-3dr-enteringpointprocedure) in the scene.
  2. Enter the XYZ values of the vector in the edit controls or click on the icon ![Normal1.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Normal1.svg) to define a [direction](http://wiki-tdg.eu.hexagonmetrology.com:8090/display/Hlp2025x1/DefineNormalDirection) in the scene.

> [!WARNING]
> ### Notes
> 
> - Fixed parameters are not compatible with more than 4 points clicked.
> - You may encounter an error: "Impossible to compute a cone with an angle equal to *x°*" that prevents from creating a self intersecting cone.

> ### Technical information
> 
> At least 4 points are required.
> 
> | Number of clicked points | Rule |
> | --- | --- |
> | N = 4 | The first three points define the base circle. The fourth point is used to calculate the angle and length. |
> | N > 4 | A best cone is done with all the clicked points |
