Creating Threshold Lines at Front and Back Doors: Adding Dimension to Your Floor Plan

Adding Threshold Lines for Front and Back Doors: Enhancing Visual Integration and Dimensional Clarity

This article discusses the importance of considering floor transitions in architectural drawings, particularly at entrances such as front and back doors. The author demonstrates how to create these details using tracking and ortho tools.

Key Insights

  • The article highlights the need for careful consideration of floor transitions at the front and back doors in architectural drawings. It suggests that these areas require more detailed rendering due to the differing floor levels and the presence of thresholds.
  • Using tracking and ortho tools, the author provides a step-by-step guide on adding threshold details to the drawing. These tools help create a one inch by one inch corner above and below the door, extending one inch past the wall.
  • The addition of these details significantly enhances the visual quality of the drawing, giving it a more three-dimensional and realistic appearance. This demonstrates the impact of meticulous detailing on the overall presentation of architectural designs.

Now that we've opened the conversation for what the Bath tile is doing on the floor, we need to think about what our floor is doing at our front door and back door. If I Zoom in, I can see that there's no line here and also no line here.

If I'm assuming that the outdoor space here is the exact same floor as the indoor space here, then it might be okay. Like the condition between B and B, these are probably the same floor type. However, I know that the ground is lower than the door here and lower than the door here.

While there's not a series of stairs, there is a threshold at each of those locations. So I would like to add our threshold lines in. We will also see these thresholds in Elevation, so it might be helpful to have them drawn in as a reminder.

Let's go and choose A Door to be our current Layer, and now I'll Zoom in on Door C, which is the back door. This is a fairly simple threshold detail, so we should be able to draw it fairly quickly. To start, I'm going to go Line, and I'm going to hit T-R-A, Enter for Tracking.

The threshold goes past the wall by one inch, so I'll start Tracking here. I'll go up one, Enter, Enter to say I'm done Tracking. Now I'll turn on Ortho, and I'll go out one, Enter.

Then I can come down the width of my door plus two inches. This door is two feet eight, so I will go two feet ten, Enter, and I'll come back in towards the wall, one, Enter, Enter to say that I'm done. Now we've added a one-inch by one-inch corner above the wall and below the wall, above the door and below the door, and it goes out one inch past the wall.

Let's do the same on the other side. I'll go Line, T-R-A, Enter for Tracking. I'll pick this point here.

Again, I'll go up one, Enter, Enter to lock it in. With Ortho on, I'm going to the right one, Enter, then down the width of my door plus two. This door is three feet, so I will use three feet two, Enter, show to the left a distance of one, Enter, and Enter to say that I'm done.

I'll turn off Ortho. I'll do a Zoom Extents, and I'll Control+S to save. Right away, you can see what kind of visual difference that makes.

Now our drawing automatically looks like it's floating or separate from the background, even though it was just a simple series of lines that we drew. In the next video, we will start to add our dimensions.
