I am working on a school project and i am almost done the last things i need to do is to put in all the dimension in a drawing but when i try to select the parts that i have used the fillet or chamfer on it only says ''the selected entity could not be converted into a line or circular area'' and i cant target them at all, the lines i try to put dimensions on are first in section view then in detail view if that makes any difference.

I have never had any problem putting dimensions on lines like these before.

What must i do to be able to put dimensions on these?

Thankful for any help!
