As an electronics hobbyist and student, I often find myself in a situation where I have to interpret mechanical drawings, such as those describing the physical properties of connectors and encapsulations.
Occasionally there are symbols that I do not recognize, and since it is difficult to use Google ("wavy line in a circle in a box with two numbers on top"), it would be nice to have a place to ask trivial questions, usually one of these two:
- What does this symbol mean? How is it significant?
- I can not find or derive the distance between these two features - why is it not stated?
So, can I ask them here? I would seem like a perfect fit, except that it is hard to make such a question interesting or useful for others. "Here's a picture, what does this mean?" is not easy to search for, leading to the questions perhaps being inherently of a low quality.
