Spiral-threaded bolt, Part 4: Extending the shankTo extend the shank end of the bolt, first, set another Guide point to determine where it should end.
Measuring from the end of the bolt, the bolt is 5 inches long. Type 5, hit Enter ...
Extending individual component sections is unnecessarily painful. Instead, by drawing a line across the diameter of the bolt's shank end, we create two new faces ...
Then, we select the same line,
and delete it, to convert two faces into one.
Zoom out so you can see the end of your Guide, select Push/Pull, and highlight the face you've created.
Left-click to select this face, and Pull it up to the Guide point. Move your mouse over the guide point itself to force the face to "snap" even with this point. Release the left mouse button.
Reselect this face, without its circumference (just click on it again, if the circumference highlights as well).
Delete this face.
