I am not because there is no way to turn the change the slope or elevation button off in plan view, as I stated in me previous comment!
Well, no, there isn't. What else could there be? Either add a vertical or change the slope, how else are we going to connect them. For now we're confined to our stupid three dimensional space.
You're getting "no auto route solution found" error either because your conduit type settings aren't setup properly, or you're trying to cram them to a space smaller than the fittings can fit.
Like I said before I hate running conduit because it doesn't work.
There are many quirks and Revit "rules" which you have to follow, but people are running pipes, even sloped pipes, even on large projects. Conduits should be even easier.
I can turn off automatically connect but not slope or vertical.
Again, how do you plan to connect them, if by neither a vertical nor a sloped one?
Here's a little video of mine. Note that I do plumbing and this is the first time I'm touching conduits, but it's my understanding that in Revit those two are pretty similar.
You need to invest time or enroll in some MEP course to learn how to do it.
It absolutely isn't ideal and there are a hundreds things that could be improved, especially in sloped piping, but it's not impossible, or even that difficult once you learn how to do it (learning includes setting up your system, conduit routing preferences, finding families that are right for you, and learn how to use all of that together). Getting frustrated over how Revit does things won't help you, and you can forget about Autodesk ever fixing anything, they don't care.
Is something like this what you're trying to do:
