IFC is a format for exchanging models with data attached between different software. IFC elements are 3D construction elements and objects. IFC has nothing too with plans, annotation, or anything 2D. The only consultant I have worked with is StructureCo, which is a pseudonym. The type of work is custom residential -- mostly wood members with some steel. This is

The user has requirements. The software has capabilities. Where the capabilities end and the requirements keep going is a limit. To get beyond the limit requires workarounds. Some limits are harder than others and all we can do is wish (beg) them removed. Here's a rich example concerning structural posts (columns) in residential construction. These are things like 4x4s, multiple
Location: 06 Wood & Plastic A beam, or any other ceiling element, should be shown dashed in the architectural plan, because it's overhead. That same beam needs to be shown solid in the reflected ceiling plan, because then you're upside down looking straight at it. Using a conventional beam element, you would draw it with a dashed line in plan.
Location: 03 Concrete A 3D concrete beam with rebars, and/or a 2D symbol of a concrete beam section. Placed in... Model means a 3D beam that will show up in plan and section. Note that the actual placement will very likely take place in the plan window. 2D Detail means a 2D symbol of the section through the beam, suitable
Kinda looks like a jellyfish This image shows a few isolated elements from a lighthouse-looking tower structure. The 54 columns are balusters for the stair railing. The 110 objects are wood beams for the roof framing. By themselves, it's not a lot of elements, or even a lot of polygons. Yet these guys were found to be the cause
Everything in the general framing plan discussion also applies to roof framing plans. There's a few special considerations: • The roof framing plan should usually be generated from the top occupied story, not the roof story. For most projects, this is either the attic or the second floor. In the past, we have used the roof story, but not
Rules for framing plans. Foundation plans are slightly different. Roof framing plans are very similar. I'll have a separate note for them. I wonder what the difference between 'slightly different' and 'very similar' is. • Walls. Display of walls is controlled by Display Options. The 'Cut Fills' option should be set to 'Separators Only'. The walls will be clear,
Location: 05 Metals (Old object, new write-up.) An object for modeling and annotating W shape steel members. It should behave similarly to Wood Beam JAM9. So I can copy and paste a lot of the documentation. Also, that post has screen shots.
In framing plans, it's often helpful to show the walls on stories below with dashed lines. Especially roof framing. Well how do you do that.
The foundation plan shows the foundation walls, footings, slabs, and related annotations. Everything that touches the ground. It can be combined with the first floor framing, but an independent foundation plan can give more information with less clutter. The layers, layer combination, and views required are included in the templates. • What Shows. • All plan walls, A Wall
Some typical applications for Wood Beam JAM9.
Location: 06 Wood & Plastic / Structure An object for modeling and annotating wood structure elements.
Location: 06 Wood & Plastic : Structure A 2D symbol for framing in section. It's been around a while, but I added a couple things. Choose the member type (2x, TJI, LVL) and the spacing. The spacing can be customized. In building sections (1/4" and 3/16" scales), the label or the joists themselves can be turned off. The label turns
This layer sort of "forks off" from the layer S Slab. Use it for framed structural decks (TJIs, 2x12s, etc). Continue to use S Slab for concrete slabs. Why? Because decks aren't slabs. Yes, they're both made with the slab tool, but layers represent project elements, not tools. As much as possible, layer names should represent real things. Where does
Location: 05 Metals This object can take the form of any steel column in the AISC manual. You can set the shape, dimensions and strength. Label it with Description JAM9. You can choose to model the top bearing plate. You can display the column dashed below. This is very helpful in developing framing plans: Show the columns overhead to make
Location: 06 Wood & Plastic : Structure. TrusJoist has updated their product line. The TJI model numbers which end in '50' are being phased out. You should stop using them immediately. You should modify the structure plans of any current project not under construction. I have updated the objects which contain TJI specs with the new model data. The old
I have updated all (I think) the objects for structural beams and such, so that the 3D model can be turned off. This enables you to put all the beams on the layer S Beam, rather than putting the ones you want to be 2D only on +S Struct Note. It's neater and more consistent this way. The effected objects
Location: 05 Metals A steel pipe column. Pretty simple. Why use it instead of an actual column? Because columns are evil. Not really. Columns are evil, because they interfere with walls and allow walls to interfere with them. But the reason to use the object is so you can still show the column solid when you set the construction fills'
