Coil
Coil shape
Selects a profile and axis and specifies the direction of coil rotation. Profile and axis must be in the same sketch unless the axis is a work axis.
- Shape
-
Profile Selects a single profile automatically. If multiple profiles exist, specify one.
Axis A straight line or work axis that defines the axis of revolution. It cannot intersect the profile. To reverse the coil direction, click the direction icon.
Solid If there is more than one body, selects the solid body to act on.
- Rotation
-
Specifies if the coil rotates clockwise or counterclockwise.
- Output
-
Solid Creates a solid feature from a closed profile.
Surface Creates a surface feature from one open or closed profile. Can be a construction surface on which other features terminate.
- Operation
-
Join Adds the volume created by the coil feature to another feature or body.
Cut Removes the volume created by the coil feature from another feature or body.
Intersect Creates a feature from the shared volume of the coil feature and another feature or body. Deletes the material not included in the shared volume.
New solid Creates a new solid body. This selection is the default if the coil is the first solid feature in a part file. Select to create a body in a part file with existing solid bodies. Each body is an independent collection of features separate from other bodies.
A body can share features with other bodies.
Coil size
Determines how the coil is created by specifying Pitch, Revolution, Height. Specify two of the three parameters; the third parameter is calculated.
- Type
-
Specifies a pair of parameters: Pitch and Revolution, Revolution and Height, Pitch and Height, or Spiral.
- Pitch
-
Specifies the elevation gain for each revolution of the helix.
- Height
-
Specifies the height of the coil from the center of the profile at the start to the center of the profile at the end.
- Revolution
-
Specifies the number of revolutions for the coil. Must be greater than zero, but can include a fraction (for example, 1.5 turns). The number of revolutions includes any end conditions that you specify.
- Taper
-
Specifies the taper angle, if needed, for all coil types except Spiral.
Coil ends
Specifies End conditions for the Start and End of the coil. Only the helix is flattened, not the profile of the coil.
- Natural or Flat
-
To specify Natural or Flat for both ends of the coil, click the down arrow. Ends can have dissimilar end conditions.
Transition angle -
The distance (in degrees) over which the coil achieves the transition (normally less than one revolution). The example shows the top with a natural end and the bottom end with a one-quarter turn transition (90 degrees), and no flat angle.
Flat angle -
The distance (in degrees) the coil extends after transition with no pitch (flat). Provides transition from the end of the revolved coil to a flattened end. The example shows the same coil as the Transition angle shown previously, but with a half-turn (180 degree) flat angle.
