Spiral-threaded bolt, Part 2: Assembling the spiralThe threaded part of the bolt is trickiest, so I do it first. I start with my "shoulder" or shank-to-spiral transition piece.
Select your Move tool. Click on the shank piece, and hover your mouse over the endpoint you want to use as handle for moving it.
Left-click and hold down the mouse button, dragging it until the shank endpoint matches up with the thread component, which will turn purple. If it looks to align nicely, release.
Rotate the view so you can be sure that the pieces connect properly.
Now, we need to extend the thread. The total threaded section in this bolt is one inch long. At 16 threads per inch, this means 15 central thread components, plus the shank transition at one end, and the end-thread component at the other.
Using the Move tool, join a central thread component to the shank-transition piece. Select an endpoint that is easy to join to its counterpart on the other component.
Left-click, hold and drag, and release.
Now, you only need fourteen more. Easy.
Hold down the Control button while you re-select the piece you just added using the Move tool. With the Control button down, select your endpoint, left-click and hold.
Drag down the copied section, lining it up with the original, and release. co
Yes, you could do this thirteen more times. Or, you could just type "13x" (minus the quotation marks; this will show in the Value Control box at the bottom right of the program interface) and hit Enter.
Thirteen more copies are added, using the same alignment and spacing.
Finally, add the end-thread component. Select it using the Move tool ...
and move it up, joining the appropriate two endpoints. Rotate and view from below, to make sure the whole assembly looks right.
