Mastering the technicalities of AutoCAD is paramount for smooth architectural designs. This article provides an in-depth explanation of various ways to input feet and inches into AutoCAD while working in an architectural template, and why some conventions might not work.
Key Insights:
- The base architectural unit in AutoCAD when using an architectural template is inches, hence, it's not always necessary to define this unit.
- Inputting the wrong syntax, such as adding a space between the feet and inches (e.g., two feet space six inches), can lead to inaccurate measurements because AutoCAD can interpret the space as an 'enter,' resulting in an incomplete input.
- Other forms of incorrect syntax include using a comma and omitting the units, which can lead to misinterpretations as coordinates in the absolute coordinate system or shorter lengths, respectively.

Before we start drawing our kitchen and bath symbols, I'd like to take a minute to quickly discuss how we input feet and inches into AutoCAD. We are working in an architectural template in this course, and when we use an architectural template, we use feet and inches, where inches are the base architectural unit.
On the left side of the screen, you can see five good ways to type in two feet six inches. On the right side of the screen, you can see five ways to not type two feet six inches, and we'll talk about why each one of those ways does not work in AutoCAD. First off, we see two apostrophe six.
In AutoCAD, the apostrophe represents an architectural tick, which represents a foot. So two apostrophe six enter will be positively recognized by AutoCAD as a distance of two feet six. You'll notice that you can also add the quotation, which represents an inch symbol.
It's not always necessary because inches is our base unit and does not need to be defined. You can also add a dash, which you'll see on dimensions on blueprints. Additionally, because inches are our base unit and two feet six is equivalent to 30 inches, you could type 30 or 30 inches to input the same value of two feet six inches.
Now, let's take a look at some other ways to input two feet six and see why it won't work. Two feet space six apostrophe and two feet space six and two space six. All of these are not going to work because of one thing, the space.
When you hit the space bar in AutoCAD, it can sometimes mean enter. If we were to type two feet space six inches, all we would really type is two feet space, which AutoCAD would count as an enter, and our distance would only be two feet. Two six would be a valid entry, but notice that it's two six, not two feet six.
So that would be counted as 26 inches, which is four inches shorter than 30 inches. Finally, at the bottom, two feet comma six inches. This one is going to be counted in many workflows, but it would count as a coordinate in our absolute coordinate system, not as a length value.
When we go through the course, I will be converting some of our dimensions directly to inches, and I will also be using this top value a lot, which is our foot with the apostrophe, and then the inches without the quotation mark. In the next video, we will begin our kitchen and bath fixtures.
