Another way to select geometric entities is to define an enclosing Cylinder (
) to select geometric entities that are completely or partially inside the cylinder. To add this node, right-click the Definitions node and choose Selections>Cylinder.
) to select geometric entities that are completely or partially inside the cylinder. To add this node, right-click the Definitions node and choose Selections>Cylinder.Define the dimensions of the cylinder by entering the radius and the positions of the upper and lower faces on the cylinder axis in the Radius, Top distance, and Bottom distance fields. The unit is the length unit for the geometry. The default is 0, Inf, and -Inf for these settings, respectively.
Position the cylinder by entering the center position in the x, y, and (for 3D) z fields. The default is 0 for all coordinates.
Set the cylinder axis by choosing an Axis type: z-axis (the default), x-axis, y-axis, Cartesian, or Spherical. If Cartesian is selected, enter coordinates for x, y, and z. If Spherical is selected, enter angles for theta and phi (unit: deg).
For the selections made under Input Entities, define the dimension of the cylinder and select the condition for the geometric entities to be selected. Choose an option from the Include entity if list: Entity intersects cylinder (the default), Entity inside cylinder, Some vertex inside cylinder, or All vertices inside cylinder.
See Ball for the settings. The only difference is that the settings are for a Cylinder instead of a Ball.
