Hi all,
I need help with a very basic project. After looking at people’s ability on this site, I’d imagine it would be very easy for most of you. What I need is this arch, but with two additional blocks added.
Is anyone willing to take this on?
Thanks!
Hmm, well, to do that, I would create a simple arc, and then use CTRL + R to create some loops! You can use the scroll wheel to increase/decrease the number of cuts. 
Another good option would be to use the bevel tool on a curve like so (6:13):
