6.1.4.4.2. Spin Solid

It allows the user to create the spun solid geometric entity by rotating the surface. For reference, this function spins the curve with respect to the user-defined rotation axis.

6.1.4.4.2.1. Modeling Options

The user can create a spun solid geometry by the following procedure.

Profile, Axis
- Profile: Selects a closed-loop profile.
- Axis: Defines a rotation axis. At that time, the user can define the axis as the marker axis or an edge of the selected geometric entity. Additionally, if selecting two points, the direction is determined automatically from the start point and the endpoint.
Surface, Axis
- Surface: Select a surface.
- Axis: Defines a rotation axis. At that time, the user can define the axis as the marker axis or an edge of the selected geometric entity. Additionally, if selecting two points, the direction is determined automatically from the start point and the endpoint.
WithDialog
- WithDialog: Spin dialog box is shown. The solid is created by clicking OK in the Spin dialog box.

  - Color: Specifies the color of the solid to be created.
  - Point: Defines the center point of spin.
  - Direction: Defines the axis to spin.
  - Angle: Defines the angle of spin.
  - Add/Remove: Selects several faces of any geometries the user wants to add or remove.
  - Add/Remove (Continuous): When using Add/Remove, if this option is checked, the connected faces within the degrees are selected together.
  - Tolerance (Degrees): The angle between the connected two faces.
  - Preview: Previews the solid to be created on Working Window.
  - Update: Update the preview.

Axis Start Point: Defines the start point to determine a direction for rotation.
Axis End Point: Defines the endpoint to determine a direction for rotation.
Rotation Angle: Defines the rotation angle.
