RD, the lowest level was already there on Layer 3. I just had it set to "hidden" (options/layers) so the other tracks could be seen better.
Be that as it may, for some reason you set the lead to tracks to the turnout to 34" and the lower level tracks to -20". Since my lower level is still there on Layer 3, I moved yours to Layer 4 and moved the grade tracks to Layer Grades. The problem is that by using 0", 7" and 14" heights, the slopes between the top level and the lowest level are 3.8% & 5.2% and I'm not sure there is enough clearance for the tracks on the middle level.
However, looking at the drawing again, it appears that the grades should actually begin much further up the line. They cross under the tracks leading to the turntable, so they have to be much lower before they get to that point. I think this is what Carl meant when he suggested it needs to be started over from the beginning. Now that I see what's happening, at the very least each run should be on a separate layer so they can be worked on individually. As it is, it gets very confusing. The photo doesn't help much unless you really study it because the elevation changes aren't very apparent. I'm busy the next few days, so it will be awhile before I can play with this again. I'll post my file so you can see what I mean and what I did.
