Hi,

i am trying to figure out what scedules in revit are actualy accurate and usefull,

now i am trying to get a floor volume schedule to work but i have noticed that revit does not subtract any volume when a wal cuts into the floor when joining a wall and a floor?

any ideas on this?

and what are the most used schedules you guys use?

using rac 2010

Kind regards,

D

Whether you use the join command, or let Revit join them for you upon completion of the sketch, the join is more or less for graphics / details reason. It makes it look better, easier to detail, etc. But it doesn't really affect how the model is genereated.

If you draw the floor sketch to the exterior face of the walls, then tell Revit to join them, Revit is NOT moving the floor sketch to the interior faces. If you want accurate volumes, you need to draw the floor sketches exactly how they should be.

The attached image show what I am talking about. The bottom floor  was joined to the wall, but notice while it is selected, the highlight still shows it going to the exterior face.

The top floor is not joined and looking at their properties, they both have the same volume.

dafpfy,

Revit will not subtractthe wall volume off the floor, if you want to simply edit the sketch and draw around your wall. Schedules are accurate as can be. we use most schedules.

in some projects we actually model every element and create a schedule for everything! simply because the project itself becomes the database (which is exactly what Revit is: a database)

hi,

the only way i see getting exact volume calculations for my finishing floor layers is working with rooms,

i have added a pic to demonstrate,

the concrete is how the floor is drawn and i can get the correct volume for the concrete, but the toplayers get cut out in all sorts of places.

how would you go about scheduling the volume of those 3 finishing layers?

We draw finishing as separate floors.  We can then get separate quantities.  Sometimes the brick wall goes to top of the structure floor and sometimes the wall is lightweight and sits on top of the finish floor (say floor tiles) 

The finish is generally not the same throug, so we never use a slab with finishing 

We use schedules extensively and often just to check the data for accuracy.  For exsample check the off set from base level, check for left over walls, beams, columns etc.  Check that the global change actually took place so we do not have two left over 'old' wall types
