This is a YouTube video. This Dimension is not given in the drawing but it is assumed 22.5 to sketch. I wish to know whether it is correct to do so.

That's not a bad assumption and it is fairly common practice.

What you meant by correct or not ? you mean over-dimension?

Dimension is decided by View Judgement only. Whether it is correct to determine a Dimension by assessment not by calculation.

huh.... ? you asked question about how to dimension a dwg or a definition of dimension?

Industry standard 22.5 is concerned an assumed dimension

Thanks.
