I'm sure this is simple but for some reason I have a 4" gap between the first and second floor in my model. Reference point is aligning and the offset for the wall is the truss depth plus decking I am stumped. It does not happen all the time.

Did you draw a slab on the first floor? If so, set it to offset 4" down.

Hey Jon - It's on a crawl space (Flood Area) so the first floor is 2"x12"  so the offset is set to that.

Are the 1st floor walls all the same height?

I asked because if the reference point is higher than the zero for the 2nd floor everything else will be too.

Yes if you have a first floor wall that is taller than the rest, then the second floor is going to reference off the tallest wall....

Not if you use the circular reference point. The circular reference stacks at the heights specified at the reference point.

I didn't know you could set an elevation at the reference point.

It's whatever elevation the wall is that you put the reference point on. If you put it on a wall that's offset for some reason, everything that stacks will pull to that elevation.

The circular reference point is the one you want to use. It will pull the floors together, both horizontally and vertically, at that location. Make sure the walls at that location, on each floor, have the same height and the same offset. They can be different from floor to floor as long as they are the same on each location.

The fit to roof was throwing my reference walls off. Thanks for the help all.

When models get complicated it is sometimes best to set walls you can hide and not extract in 3D away from the model and set the reference point on those walls to keep the offsets clean. Whatever heights you set those walls to will dictate the stacking of drawings and can lessen the possibility of messing up with walls raking, fitting to soffit, or anything else you make do in the actual building model.

Cool... I didn't know that. Typically all my walls are the same height but, I'll have to remember this for future models.

Great Tip Mark that's what I ended up doing.
