Screw

Relevant to Blender v2.31

The "Screw" tool combines a repetitive "Spin" with a translation, to generate a screw-like, or spiral-shaped, object. Use this tool to create screws, springs, or shell-shaped structures.

The method for using the "Screw" function is strict:

If there are multiple 3DWindows, the mouse cursor changes to a question mark. Click on the 3DWindow in which the "Screw" is to be executed.

If the two "free" ends are aligned vertically the result is the one seen above. If they are not, the translation vector remains vertical, equal to the vertical component of the vector joining the two 'free' vertices, while the horizontal component generates an enlargement (or reduction) of the screw as shown in Figure 6.48, “Enlarging screw (right) obtained with the profile on the left.”.
