shape.Cylinder

Create closed cap cylinder centered at origin

Since R2023b

    Description

    The shape.Cylinder lets you create a cylinder with metal and dielectric material properties centered at the origin. Use this cylinder along with the other shapes and the geometric operations to create a shape for the custom antenna.

    Creation

    Description

    cyl = shape.Cylinder creates a closed cap cylinder centered at the origin.

    example

    cyl = shape.Cylinder(Name=Value) sets additional Properties using one or more name-value arguments. Name is the property name and Value is the corresponding value. You can specify several name-value arguments in any order as Name1=Value1, ..., NameN=ValueN. Properties that you do not specify retain their default values.

    Properties

    expand all

    Cylinder name, specified as a string.

    Example: "Cylinder1"

    Data Types: string

    Cylinder center point, specified as a three-element vector of Cartesian coordinates in meters.

    Example: [1 1 1]

    Data Types: double

    Radii of the top and bottom faces of the cylinder in meters, specified as either a scalar for same radii values of the cylinder faces or a two-element vector for different radii values of the cylinder faces.

    Example: 2

    Example: [1 2]

    Data Types: double

    Height of the cylinder along the z-axis, specified as a scalar in meters.

    Example: 4

    Data Types: double

    Flag to keep or remove the top or bottom faces of the cylinder, specified as a two-element logical vector. First element of the vector represents the top cap, while the second element represents the bottom cap. Use 1 to keep the cap, while 0 to remove the cap.

    Example: [0 1]

    Data Types: logical

    Metal material of the shape, specified as a metal name string from the Metal Catalog.

    Example: "Copper"

    Data Types: string

    Dielectric material of the shape, specified as a dielectric name string from the Dielectric Catalog.

    Example: "Teflon"

    Data Types: string

    Color of shape, specified as either a character for color short name or a three-element real vector of RGB triplets. The default shape color is yellow. See the Types of Color Values supported by this property. When you unite two shapes of different colors, use "Individual" value to retain the colors of the original shapes in the resultant shape.

    Example: "r"

    Example: [0 0.447 0.741]

    Data Types: double | string | char

    Transparency of shape, specified as a scalar in the (0,1) range, where 0 corresponds to full transparency while 1 corresponds to full opaqueness.

    Example: 0.75

    Data Types: double

    Color of shape edges, specified as either a character for color short name or a three-element real vector of RGB triplets. The default edge color is black. See the Types of Color Values supported by this property. When you unite two shapes of different edge colors, use "Individual" value to retain the edge colors of the original shapes in the resultant shape.

    Example: "b"

    Example: [0.4940 0.1840 0.5560]

    Data Types: double | string | char

    Examples

    collapse all

    This example shows how to add two 3-D shapes and view the combined shape.

    Create a box and a cylindrical shape.

    b = shape.Box;
    c = shape.Cylinder;
    j = add(b,c)
    j = 
      Custom3D with properties:
    
                Name: 'custom3D'
            Vertices: [100x3 double]
               Metal: 'PEC'
          Dielectric: 'Air'
               Color: 'Individual'
        Transparency: 'Individual'
           EdgeColor: 'Individual'
    
    

    Alternatively, you can use '+' operator to add these shapes.

    b + c; 

    Figure contains an axes object. The axes object with xlabel x (m), ylabel y (m) contains 3 objects of type patch.
