I wanted to draw this rail profile (uci54) in the sketch workbench. I have not any problem with other dimensions except (1:2.75) and (1:10). They are unknown to me, though I think are relative to gradient. How do I draw them?
When I encounter a technical problem, I often refer everywhere to find a solution, if it even takes long for weeks. I never give up an unsolved matter unless I realize it is out of my knowledge boundary.
When I pose a question here or in other engineering or technical communities, I research about that issue everywhere simultaneously to find the solution sooner.
After I sent this question, I reviewed a variety of the rail sections until I found the answer of my question in one.
Of course, I didn't know its terms (Rise: Run) and learned it from you
