Create an Implicit Primitive

Create simple geometric shapes that can be used for repetitive tasks or combined into more complex shapes. Implicit primitives include a cuboid, cylinder, and sphere.

Each primitive type has controllable position, orientation, and dimension.

  1. On the Implicit Modeling ribbon, select the Primitives tool.

  2. Optional: For Visualization Quality, select from Low to Very High quality, which corresponds to a low to very high density of elements that are used to sample the underlying field of the primitive shapes. A higher quality produces sharper geometry features but is more computationally intensive. When creating a complicated function, it’s recommended to work using a lower quality and then switch to a higher quality after the function is complete.
  3. In the guide panel, select a shape:
    • Cuboid
    • Cylinder
    • Sphere
  4. By default, you can move the primitive using the graphic manipulators in the modeling window. To move the primitive by entering values, turn on Manual Entry, and then define the x-, y-, and z-coordinates of the origin. The x-, y-, and z-coordinates can be variable driven or constant.
  5. If you selected Cuboid, to make a cube, turn on Uniform.
  6. Adjust the dimensions, which can be constant values or variables.
  7. Click OK.
