Hi Everyone,

I'm rather new to revit and using 2012.

I have a question. more of a rant. But I hope someone have seen this before

ARE YOU TELLING ME MATERIAL TAKEOFF CALCULATES BOTH INTERIOR AND EXTERIOR LAYERS AS SAME VALUE IN A BUILDING?!

No really. One of the main reasons we are moving to revit is to have an accurate number for the materials that we minimize time and human errors.

Attached is a rvt file (2012) That illustrates what I mean it has 2 walls in an L shape and a wall material schedule.each wall has 5 layers (paint exterior| plaster| block |plaster| paint )

Anyone has a workaround? I convinced my boss of moving to revit(wasn't hard) but now I have to get around this bump.

your post does not explain the issue very well; (and your photo doesn't load, maybe its my browser) the take off will calculate totals of different materials, but you need to do things like specify 'interior paint' and 'exterior paint', not just  'paint'

I'd rather be riding at whistler. or highland. thats good too.

Thanks For the reply pepsiqueen. I took a look and I have good news: your browser is OK I can't load the image neither.

I reuploaded another one I hope it explains What I mean

The interior finishing Should be(4+5)x4 sq m = 36

exterior finishing should be (4.2+5.2)x4 sq m = 37.6

apparently revit is calculating both from the centerline that how it got them equal

on a large project, the difference is thousands of $$$

Just a thought: does mitering the wall join change the values? The selected wall in your image has the same surface area on the interior and exterior if it is calculated as shown.

Thanks jterrel. it does.

Although it may be helpful if someone can tell me y that happened. It looks the same and it should have been the same value

value.

Image attached.

Now all I need to do is go through my project and make sure all corners are mittered and see what I need to do in T joints

so I don't get similar inaccuracies.

If the outside skins are the same, then your overall values will be the same with either joint.

Thanks for the reply wwhub, actually thanks for all your effort.

Please look at both my images. same dimensions different mitter different value.

It should be the same but its not.

This is a 3D world and plans don't tell it all.  Even with properties the same. there are still possible differences. 

 

I suggest that to understand REVIT, you do some simple testing using walls and model that can easily be tested.  That means walls that are 10x10x10 with different interior & exterior skins... then using takeoff schemes and recording them:  (Oh - and BTW - pay attention to layer priority settings as that can affect material take off.)

  1. By itself
  2. joined with another wall 10x10x10 with different skins ... and then with different join options
  3. see what hapens with inserts like doors
  4. see what happens when layers can be altered with pull downs
  5. See what happens when joined to a penetrating floor

If you intend to use Revit in this capacity, then you have to understand exactly how it works in many situations... and these are just a few.

Dear WWWhub.

Exactly what I'm trying to do and What led to the original post.

I'm getting some interesting  results.

Problem is I told Manager Revit can give you accurate Material Quantities instantly and interactively. I wish it was more straight forward (or I can withdraw my statement).

What is layers canbe altered with pulldowns??

Thanks

From your HELP:

 

Allowing Layer Extension

If you select the horizontal outer boundary at the top or bottom of a layer, you can specify whether that layer can be extended.

Select a horizontal boundary at the top of the wall, and a padlock displays. A locked padlock indicates that the selected layer cannot be extended. Click the padlock to unlock it, and the layer can be extended.

 

Unlocked layer indicating extendability

(See attached image)

When you unlock layers for extension, 2 instance properties of the wall become enabled: Top Extension Distance (for layers at the top of the wall) or Base Extension Distance (for layers at the bottom of the wall). You can enter values for these properties in the selected wall’s Element Properties, or you can drag the unlocked wall layers in a view.

NoteUnlocked layers must be adjacent. For example, you cannot have one layer locked and its adjacent layers unlocked.

To drag wall layers, modify them in section, 3D, and elevation views.

 

To drag wall layers

  1. Place the cursor at the top or bottom of the wall and press Tabuntil you highlight the shape handle for the extendable layers.

    Watch the status bar to be sure you are highlighting the shape handle.

  2. Click to select the shape handle.
  3. Drag the shape handle up or down.

(SEE ATTACHED IMAGE)

TipIf you join 2 walls and they both have a vertical extension, the extended portions will be horizontally joined. The extension joins must be the same, top-to-top or bottom-to-bottom.
