Best Cylinder

This command computes the best cylinder from the input objects.

Requirements

Select the object on which you want to compute a best cylinder and launch the command.

You can force the radius(or the diameter), the center or the axis:
1. Enter the XYZ coordinates in the edit controls or click on the icon to click a point in the scene.
2. Enter the XYZ values of the vector in the edit controls or click on the icon to define a direction in the scene.
You can remove noisy points using Eliminate worst points. A new shape is computed every time you modify the value.
If you use several input objects, you can choose to compute One shape per input or a best shape for all objects together.

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.

Tips & Tricks

Sometimes, when you compute a cylinder, an incorrect extraction may occur. In this case, you can try to “help” the software by entering an approximate axis:

Adjust the 3D view so that the view direction nearly corresponds to the cylinder axis.
Check axis and define the direction with the button ( normal to screen). The extraction should be more accurate.
