We are going to produce the stud with domed ends and cosmetic threads. The cosmetic threads are a way of showing threads in a drawing by adding information (annotation) to the model. It is posible to model the threads in 3d but this would not give us correct drawing information, or a drawing to engineering standard.
The dome is straight forward. This information is part of the initaial revolve feature. Sketch the rads on to the ends of the sketch - ensure the rad centres are at the centre line. A centre point arc is the best method of doing this. Try to use a minimum number of dimensions; use relations where possible; the two rads are equal and the vertical centre line is attached to the mid-point of the two horizontal lines.
The cosmetic threads are added individually to each end. The threads are blind with the distance set correctly. Make sure you are selecting the standard ISO, the system will work out the size information from the geometry (although several M12 thread options are available - the M12 is the standard thread). The cosmetic thread can only be added to an edge, you cannot select the face of the cylinder. Cosmetic thread is found under annotations on the insert drop down menu.
