When designing a wall with moldings and reveals, what type of detail should be drawn to convey the depth and profile of the reveals?

APlan detail

BVertical section

CElevation detail

DHorizontal section

Show Suggested Answer

Suggested Answer: B

Reveals are recessed or projecting features in a wall, often used with moldings to create depth and shadow lines. To convey the depth and profile of reveals, a vertical section is the best type of detail because it shows a cross-sectional view of the wall, illustrating the reveal's depth, shape, and relationship to the moldings in a vertical plane. This provides contractors with the necessary information to construct the wall accurately. Option A (plan detail) shows a top-down view, which doesn't convey depth. Option C (elevation detail) shows the wall's appearance but not the internal profile or depth. Option D (horizontal section) shows a horizontal cut, which is less relevant for vertical features like reveals.

Verified Answer from Official Source:

The correct answer is verified using NCIDQ IDFX content on construction drawings.

Exact Extract: The NCIDQ IDFX Reference Manual states, ''A vertical section is used to convey the depth and profile of wall features such as reveals and moldings, providing a clear view of their construction.''

Elevation detail could work too, but not as effective.

Totally agree, vertical sections really capture that detail!

Horizontal section? What is this, a plumbing diagram? Elevation detail is the way to go, my dudes.

Vertical section is the only way to truly capture the essence of those reveals. Anything else is just a waste of time.

Plan detail? Nah, that's for amateurs. Elevation detail is where it's at.

Horizontal section? What is this, a geometry test? Vertical section is the clear winner.

Elevation detail, for sure. Reveals are all about the facade, am I right?

I’m confused about horizontal section; I don’t recall it being used for reveals, but maybe it could show some depth?

I'm leaning towards plan detail because it gives a good overview, but I feel like it might miss some of the dimensional aspects.

I remember practicing a similar question, and I think elevation detail could also work, but it might not capture the depth as well.

I'm leaning towards the vertical section too. That's going to be the most informative view to really convey the 3D nature of the molding profiles and the depth of the reveals.

A vertical section is definitely the way to go here. That's the view that's going to give you the most information about how those moldings and reveals are constructed and how they fit together.

I think a vertical section might be the best choice since it shows the depth and profile clearly, but I'm not entirely sure.

For this type of question, I'd go with a horizontal section. That way you can see the full width and depth of the reveals in relation to the wall. The elevation might not show enough detail.

Overall, B) Vertical section is the most effective for this.

Hmm, I'm not totally sure about this one. I'm thinking maybe an elevation detail could work too, to show the overall look of the moldings. But a vertical section does seem like it would give the clearest view of the reveals.
