KOMPAS-3D v23

To select a method to determine the height of the spiral, press the corresponding button in the Height group in the Spiral section on the Parameter Panel.

By Distance
The spiral height is defined by the distance.
Set the height value in the Distance field.

By Object
The height of the spiral is determined automatically by the position of the object specified by the user.
In the graphic area, select a vertex, a face, a plane, or a surface to define the height of the spiral. The name of the object is displayed in the Object field.
Enter the required distance between the end of the element and the object in the Move field.

•If you need to plot a spiral exactly to an object, enter zero.

•If the distance to object is different from zero, this distance can be laid towards the spiral plotting direction (in this case the spiral will go "beyond" the object to the specified distance), or against the spiral plotting direction (in this case the spiral won’t reach the object, and the gap between the spiral and the object will be equal to the specified distance).

To change the direction of distance measurement to the vertex, use the To Object / Beyond Object  button, located to the right of the Move field.

By the flat curve (only for cylindrical helix)
The height of the spirals is determined automatically according to the length of the specified sketch line. The spiral, in this case, repeats the shape of the line, and the axis of the spiral is a copy of the line acquired by parallel displacement of the sketch line, where the starting point coincides with the snap point of the spiral. The plane of the selected sketch must be perpendicular to the base plane of the spiral.
Select the sketch line in the graphic area. The name of the object is displayed in the Object field.
