Explore the intricate details that go into wall sections within architectural plans. This article dives into the various elements that create a comprehensive wall section, including axonometrics, keynotes, and specific material indications.
Key Insights
- The wall section drawings provide more detailed information than the building sections, showcasing specific material patterns, insulation, and door placements.
- The scale of the wall section drawing is larger than that of the building section, thereby allowing for more comprehensive detailing, such as the types of materials used, the thickness of the wall, and the inclusion of keynotes.
- Revit, the architectural software used, presents information at different view levels, which can affect the visibility of certain systems and structures within the wall section.
Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.
Let's discuss wall sections. The initial references to a wall section are shown in plan drawings, elevations, and building sections. What this page has are two separate wall sections.
On the right-hand side of the page, you will see an axonometric, and then the actual wall section itself. On the left, you will see an axonometric and the wall section itself. Immediately, when you look at the wall sections, you can see that, unlike the building sections, they show more detail.
In the building section, all of the walls were poached. In the wall sections, we're seeing materials. If I continue to zoom in, I can see the concrete pattern right here.
I can see the wall with insulation in it, and I can also see the sliding door that accesses from the room onto the deck. When I look at the axonometric model, you may notice that the systems are poached. This is a result of how Revit presents information at different view levels.
So again, I'll pan over a bit. You can see, for example, the door over here, the header to the door, the insulation for the wall. Again, here's the door.

The header is located in this area. You can see the suspended ceiling that's in the room and extending to the floor above. You'll also notice that keynotes are presented in the axonometric.
If I pan down, you can see the marks and materials. So this again is the legend. Here is the mark, which are the abbreviations that will be used in the wall section, and here's the actual material.
The floor plan was drawn at an eighth-inch equals one-foot scale. The building section was drawn at three thirty-seconds inch equals one-foot scale. The wall section is drawn at a quarter-inch equals one-foot scale.
Essentially, the wall section drawing is twice as large as the floor plan and elevations. And for that reason, we can explain more information. I'd like to pan our way up the building.
We're seeing the foundation. Dimensional information is not provided here. That information is provided by the structural engineer.
You can see that we have different wall types, different poches. This is masonry. The masonry units are shown here. You can see here that it's saying CMU for concrete masonry. We have a callout here from the legend.
We can see that the finished material is ST3. I look over here. It's a stucco beige finish.
There is a reference to a detail located here. The detail is located on page A503. It's image 10.
You can see that the top of the concrete is anchored to the grid. There's another detail here, which is image 6 on page A503. More notes.
Room names and numbers are indicated. Another detail at the top, which is image 3 on page A503. You can see a note calling out for a roofing system.
That information will be provided in details and/or in the specifications package. Then we're also showing top of the low parapet. The low parapet is anchored dimensionally to the top grid line.
Let's pan over and look at our other wall section. Like we had a lower parapet over here on the right, we have a higher parapet over here on the left. The datum is called out, top of high parapet.
There's a detail, which is image 1 on sheet A504. So that will be at an even larger scale. You can see the column grid, the dimensions that are anchored to the grid datums.
We have some dimensioning in through here showing wall thickness. A detail reference on sheet A503. Some notes.
Room names. Pan down a bit more. I see the details referenced here.
A503. A keynote. There's a stairwell that's going right along here.
So again, Revit works using view ranges or clipping planes. And so we're not seeing the entire stair, but we're seeing the part of the stair that's in the view range that was specified by the architect when they were developing this wall section page. Let's zoom in here.
This note relates to the EIFS system. When EIFS first came out, there was an issue with water penetration. So, what they're specifying is that from this location down here to up here, the architect is requiring a fluid-applied membrane moisture barrier in the wall system.
Again, we have our footings, which are specified elsewhere in the drawing set, usually in structural. And now let's pan out. And here, we have the wall section page.
So again, we have the axonometrics, we have a legend, we have the actual section itself.
The scale is listed. The scale of the wall section drawing is larger than we would find for the building section. We have keynotes.
Many of the same keynotes point to the axonometric view, as well as the section view.
We also have other details referenced in the drawing. And again, dimensions are anchored to the grid and/or the datum elevations.
I hope you've enjoyed the review of this drawing. I'll see you in our next video.
