You can define such a profile, but when using it with the Thread command, you’ll get an error. Say, for example, you wanted a thread profile that was 0.125″ high, but you also wanted a pitch of 8 threads per inch. You can use this fact to get around the zero-thickness problem. In a nutshell, the secret is to realize that SOLIDWORKS is accurate to far more decimal places than typical manufacturing processes can discern. I have to admit it took some experimentation to first discover a method that would give him what he was looking for, and then work through the available options to develop the easiest repeatable workflow. This quandary was presented to me by a prospective customer. This is something that, in the real world, you can achieve - but in SOLIDWORKS, such a sweep setup would result in zero-thickness geometry, which is an error condition. But…What if you need to have the thread profile and pitch be the same? If the pitch is smaller than the thread root, the sweep will intersect itself of course, there is no such thread specification anyway, as it wouldn’t make sense. One of the rules for custom thread profile creation clearly states that the pitch must be larger than the thread root, and this is understandable because we’re creating sweeps. The process is pretty straightforward and explained in the SOLIDWORKS Help. What if you have non-standard threads you want to use? The answer is to create your own thread profiles. SOLIDWORKS introduced the Thread feature, which allows you to easily create standard threads as actual, fully-modeled geometry.
