Hi, I'm trying to create an equations with an arch and a straight line. What I want to happen is to when I change the radius dimension the line gets wider or smaller depending on the radius size. Any suggestions will be appreciated, thank you.

Double-click on the line's dimension. Highlight the current value and hit the Equal sign on your keyboard, then click on the radius dimension. That will create a link between the two, keeping them equal. For other situations you can enter more information after clicking on the other dimension, such as

to keep one dimension half the value of the other, or*/2*to double it.**2*Will they both be same when you change radius? I mean if you make it 5 then what would be the length of the line?

What I'm trying to show is e.g. a rod of a length "L" and I want to show it curved with different radiuses. The length "L" must remain constant. Thank you.

You need to calculate the Perimeter of the arc and make that equal to line length.

I think you may be missing a dimension The height of the arc from the line.

Then here is is what you need (check attached video) and no need for any equations.
