Explore the nuances and details of structural drawings, including referencing and communication methods in architectural schematics. Understand the intricacies of roof framing plans, hatch patterns, legends, post structures, and foundational details through a comprehensive examination of a building plan.
Key Insights
- Structural drawings employ a grid system for easy communication and positioning of information within the building design. This includes roof framing plans, detail references and hatch patterns that indicate specific building elements such as truss-framed roofs.
- Legends and schedules in the drawings provide further information about specific elements like roof framing notes and post structures. These often reference more detailed notes or specifications, aiding in the clarity of design communication.
- Structural drawings often include a method of presenting information that involves referencing other details within the drawing set. This is particularly common with details regarding foundation, roof framing and additional framing information.

If we continue on to the next page, we're at the roof framing plan. When you look at the drawing, once again, you see the structural grid system, 1 through 8 across the top, A through H along the side, again, allowing us to easily communicate with other people regarding the positioning of information within the building. Look again, and you can see that we have the detail references.
Again, if I zoom into this area, you can see that detail 1 on sheet S5.1 is going to be representing a slice right here at the building, and the first time we're seeing it is on page S3.1. You'll notice that some of this information is showing a hatch pattern. If you remember, the roof on this house is a truss-framed roof, so this is indicating that we have a fill framing. So again, we have standard trusses being used on the building, but we infill between the trusses to better allow the roof to appropriately present itself.
Over on the top right, I'm seeing that I have legends. I have my roof framing notes, and like before, rather than including all of the text within the framing note itself, I'm saying, for more information about this, go see this detail right here. I also have a post schedule.
You'll see that it's called P123, and for example, if I look in this area and over here, I'm seeing different kinds of post structures, and in the schedule itself, we're informing the people how to appropriately build the posts. Not all posts are considered 4x4s or 6x6. Sometimes we have to make them.
I go to the next page. I'm showing foundation details. Again, if I zoom into this detail, you can see that there's a detail that we're seeing here, but this detail is referencing other details within the drawing set.

If I look over here to the left, I'm seeing that on this image, I'm showing a section. So I have a section cut, A slash A, and if I look down here on the detail, I'm getting a better presentation of what that section slice looks like. So again, here's a detail referencing another detail within that drawing.
On this image down here, same thing going on. I have a section cut, and for more information regarding the specific framing, I look at section AA. So this way of communicating information within a drawing set is relatively frequent.
I go to the next page, and once again, I'm now looking at the roof framing. If I zoom here, you can again see details referencing other details, and again, we have a note. I follow the leader line, and it points exactly to where that information wants to be.
So this method of presenting information is very common within structural drawings themselves. Our next page is additional framing information. This is relatively straightforward.
Again, details with other details being referenced in them, and our last page is again more structural framing information. I hope this overview of the structural drawings has been helpful. I look forward to working with you on our MEP drawings.
