Why can't I find out how many studs and top rails I need

Anonymous — Tue, 23 May 2023 16:03:35 GMT

All of my previous work has been for large structures using steel reinforced concrete but my latest has studded interior walls. While easy to select the type of wall (steel/wood stud, thickness, gypsum, etc.) I couldn't find anyway to set the spacing of the studs. Here in Canada the maximum spacing is 16" ib center and a standard used in general. I went through all of the "lists" available and while I could show the list that indicates the wall(s) I couldn't find a list that actually showed how many studs and rails (top and bottom) that would be needed to construct the wall(s). Is there a reason for this? As my test project for this I opened a new project and place a single wall that had wood studs (2" x 6") and gypsum drywall. The wall length was arbitrary. Those characteristics were chosen in the Wall options window. Next I selected the "lumber pack cut list" but AC responded with an alert indicating that there weren't any lumber items. Really? It was obvious that AC did not realize the wall was made with wood studs even though that was stipulated in the wall options window. Anybody got any thoughts?

What object are you using?

A wall is pretty much just a wall with what ever name you want to give it.
If you want to count studs and top plates then you need to actually model them separately.
There are 'Wall Accessories' that can add the stud framing to a wall but I don't think they are super flexible.
Search here for stud framing as there has been quite a few posts about it.

Thanks Barry I will search stud framing.

Hello Barry:
I did a search as you mentioned and there are lots of posts regarding "stud framing" but it became obvious that AC does not have a built in ability to model stud framing. As you said a wall is a wall and it only recognizes the center core (studs in my case) as a single solid element. I was led to believe that AC was built with regional versions to make sure that development followed those regional building codes but maybe that is not true? As I said I did an experiment inwhich I created a project composed of a single wood stud wall of "x" length and "y" height. If I wanted this wall built by a contractor the only information I could give him at this time (meaning AC21) is drawing showing the length, height and width including a section showing the cladding (drywall). What I can't give him is a BOM or a drawing showing how the wall is constructed in AC. The reality is that I would have to use some other 2D CAD and create the necessary drawing. Now AC was the first A CAD product to include BIM but where is the "intelligence" if AC does not model objects in their entirety. The whole purpose of BIM is that the model contains all of the information regarding all of the objects. I was wondering if you knew a person at AC/GS that I could contact to discuss my concerns? Appreciate any help.
Regards

Have a look at this:

I haven't looked real close at it, but may be what you're after.

Thanks Bruce:
It would work but it would also cost me as much a full license of AC. I saw this type of setup way back with documentation which AC was not very good at. Someone came out with documentation software that would work as an Add-on and do all of the things that AC couldn't but as AC was upgraded over time the Add-on didn't work. In the end AC added all the documentation capabilities. I see the same issues with Archiframe. What happens when it is not compatible after 3 revisions, buy a new version? Can't justify.
Again, thanks.

Have you tried the Wall Framing object in the Wall Accessories download?
Is this something to what you want to do?

I have never used it so can't say it is any good for listing individual timbers.

If you don't have it already you must download the accessories (link via the HELP menu I Archicad).
Once downloaded and installed you will need to manually load the Accessories library or move it to the Archicad library - as it installs in a different location to the main library in the Archicad program folder.

Thanks Barry. Glad you said that it put the library in a different location as I had to find and add it using the library manager. I haven't tried it yet but I will next week as the weekend is here. Hope you have a good one.

I think the Curtain Wall is completely capable of modeling Wall Framing and the framing of a single Wall can be modeled using a single Curtain Wall, which means it can be edited as a whole unit. Also, the individual Frames within the Curtain Wall can be properly classified and scheduled.

Perhaps you don't need to know how many studs there are, but rather how many to order? I am a big fan of modeling the framing, however, this does not produce results too far off form standard rules of thumb for take-offs. It's not very often where the circumstances warrant modeling the Framing detail. However, when you do need to do that, how you model what is important and relative to what you need to do with it.
I typically use Columns for studs, Walls for plate. Work with pre-modeled door and window assemblies that you can quickly edit for specific conditions. Trace Reference is your friend for doing this Don't look too close -- screen shots were work in progress
