Hi,

 

To start off I am using 2012, but don't believe that makes a difference unless it is a program bug. 

 

I have 3 assembled floors, Basement and foundation, Main floor, and Second floor. When I use the reference circle on the three plans like I think I should, then the lowest wall on the main floor sits down on the footing of the foundation at the point where I put the reference circle. (see foundation into main floor)

 

Now I have noticed that when I delete the reference circle on the basement that it all looks pretty good. The walls SEEM  to sit on the foundation, but on closer inspection I find that the walls are hovering 3/4" above the foundation wall. (see other two images)

 

The reference circle is on a corner of the house that is at a 30deg angle. Can that make a difference? I have copied and pasted the walls into a completely new project and it does the same thing.

 

Wes

Using the circular reference point, The walls will always stack on top of each other using the wall heights AT the reference point. Using other reference points the "0" height will sit on top of the highest point on the floor below it.

 

Also note, that if your reference point is OFF the wall (even slightly) then it will still take the height AT the reference point. 

 

Your 3/4" difference will be caused by something in the plan. Try checking EXTRACT ALL on the 3D Extractions Options and seeing what material is causing that gap. NOTE: it may not be in an obvious location ...

 

The 30 degree angle won't make any difference.

If there is a material that is making this happen, wouldn't it show up at the point where I have put the reference circle? Once you have placed a reference circle, the way I understand, SP doesn't care at all what is on the rest of the plan; it stacks with the materials that are in the walls directly under the reference circle. 

 

The other question: Why is it almost right when I remove the reference circle on the basement, but way far wrong when I place the reference circle on the basement wall?

[Wesley Penner]

The point on the main floor where I have the reference circle even goes below the 0 baseline in the foundation plan when I have reference circles placed in all plans.

[Yvon Gonthier]

Do you have any other type of Reference point on any plans? This sometime causes conflicts.

Didn't you say you only got the 3/4" error when you REMOVE the reference circle?

[Wesley Penner]

No other reference in sight

Oh right, that is true, but I would like it to work with the reference circle and then it is way off.

 

I'll check again for that material that might cause this 3/4" descrepancy...

[Keith Almond]

A lot depends on not only the reference circle, but the zero level too. I believe that if you stack on a circular reference it only stacks the zero level on top of the circle. If your front garage wall is the wall with the reference circle, do you have it at "0" and the others above it, or is it defined as X" down?

[Jim Crook]

Is there a beam anywhere in the floor system that extends 3/4" above the foundation wall ?    I have had beams affect stacking in the past.

 

Is there any chance you have a reference point on another Layer or Bldg Option that is turned off ( not sure on this but just thinking out loud ).

[Wesley Penner]

Ok now I got it. Keith, you were right about there being something causing the 3/4" discrepancy (actully it was 1/2") My interior basement walls were too tall. 

 

Now I will just test out your theory that references stack on baseline...

[Wesley Penner]

Hmmm... It appears as if Keith is right again... Thanks alot. The problem that I have is that the garage is part of the main floor, but the floor goes 5'6" below baseline, so when I when I reference to the foundation wall for the garage (which is lower than the rest of the basement ) It references baseline of main floor with the top of the garage foundation wall. 

 

I will have to put garage floor at baseline on main floor.

My exterior basement walls includes the concrete wall which is 1 1/2" shorter than my interior stud wall so that it lines up with the interior studs walls which a 1 1/2" higher than the concrete wall and allow for my sill plate that sits on top of the concrete wall. I always attach my reference circle on the exterior corner of the concrete wall section and it always stacks properly.

Rather than change all your heights, it may be easier to relocate the reference point.

[Wesley Penner]

Yes this is somewhat of a complex plan with the Second floor being only above the garage, so nothing to reference to directly above a nice square corner of main floor which is on 0 baseline. Armed with this new information I will mess around with it and get it to work, I am sure.

 

Thanks to you all for your help.
