![CmdBestRectangle.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/CmdBestRectangle.svg)

This command computes the best rectangles from the input objects.

> [!TIP]
> ### Requirements
> 
> Select the objects on which you want to compute a best rectangle and launch the command.

1. You can force the **length**, the **width**, the **center**, the **normal** or the **main axis**:
  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.
  3. Enter the XYZ values of the vector in the edit controls or click on the icon ![Normal2.svg](https://cdn.document360.io/820e11db-8ed5-45ae-ac86-f6b77dcb2aa7/Images/Documentation/Normal2.svg) to define a [direction](http://wiki-tdg.eu.hexagonmetrology.com:8090/display/Hlp2025x1/DefineNormalDirection) in the scene.
2. You can remove noisy points using **Eliminate worst points**. A new shape is computed every time you modify the value.
3. If you use several input objects, you can choose to compute **One shape per input** or a best shape for all objects together.

> [!WARNING]
> ### Notes
> 
> If the number of points is small enough, the software calculates directly the best shape otherwise you must click the **Preview** button to launch the calculation.
