How do I go about creating a thread (with the "Drilling Assistance" feature) on a rounded or spherical surface on SolidWorks?
Hello
On which software?
On SolidWOrks you have to use a scan following a guide curve.
This guide curve will be of helical shape, and the profile will be the thread profile (usually a triangle).

For the helical, this link to the SolidWorks help is better: http://goo.gl/T9BHbu
Hello, the goal is really to make the thread in 3d or just to have a note in a drawing?

Hello
If you want this in a simulated bute.
You have to create a profile that follows a propeller.
It would be easier if you told us your CAD software and or what you want to simulate with a schematic.
Hello
create a sketch on the face of the part; then draw a circle of diameter of the cylinder
between Function - curve- helix and spiral: given all the details (pitch, number of revolutions, angle)
choose a plane that cuts the helix and makes the drawing of the net shape (triangular, square,... ect);
Enter Function - removal of the scanned material clicks on the sketch of the thread shape and then select the tracker (helix) (your thread will be made)
After all, if it's only for design purposes to annotate a drawing, there's no point in drawing this thread.
Simply create it via the Annotation tab and then bring it up via Options, Skin, Show Filter and then Shaded Thread Representations.
Your thread will therefore be usable in dimension and visible in 3D.
Of course, this remains for Solidworks but without specifying the software, it is more complicated...

Hello
A picture of what you want to achieve would help us to answer you in the best possible way.
Because indeed, if you want the shape in 3D it can only be achieved with a swipe function.
Kind regards

hi
When I have this kind of thread to perform I do it as on the example of the file I attached.
1) I create an additional plane to position the thread
2) I create a construction sketch
3) I use the drilling assistance and I position the center by eye
4) I put the 3D point of the tapping align on the axis I made with a relation
5) I update
for my part I do it every time and it works
I'll let you see the example of the procedure on the image I'm attaching
If you use SolidWorks, this technique is quick and easy if you want to use the drilling assistance
Have a nice day

@centor, a tutorial could be interesting to make. Your attached image is almost one, you just have to reshape it! Good luck
Kind regards
