Learn how to accurately design and align elements in a 3D architectural model using grid line dimensions and top constraints. Discover how to make adjustments and use tools like the tab key to select a chain of walls or lines for easier manipulation.
Key Insights
- The overall dimensions of a 3D model can be double-checked to ensure accuracy, with this article using an example of 40 feet by 100 feet.
- Grid line dimensions should match up, with the tab key being a valuable tool for selecting a chain of walls or lines to make necessary adjustments, such as setting the top constraint to the top of the parapet.
- The location line being set to finish face exterior is crucial when planning to change the wall type to a thicker variant, giving the 3D model a more realistic look.

At this point, it's a good idea to just stop for a minute and take a look at what we've done and make sure that we've got everything in the correct order and the correct location. So, the first thing I'm going to do is double-check my overall dimension. The overall dimension is 40 feet by 100 feet.
And then I want to make sure that all of my grid line dimensions match up. So, I want grid line one to be one foot six inches from the outside face of the wall, and grid lines C and A to have the same relationship. So, I'll look down at grid line five, and that one looks good.
The next thing I'm going to do is go to my 3D view, and we're going to take a look at them. We should have all of our walls going up to the top of the parapet. If I were to just click on one of the walls here in 3D, I can see that my top constraint is set to the top of the parapet.
Now, if you look at your walls and, for some reason, they're not set that way—let's say that you just left them unconnected at 20 feet, as the default setting is—and you look at it and you're like, "This is not quite right." Well, what we can do is go in and easily adjust those back up. The tab key, again, as I've said a few times, is going to be one of your favorites because we can also use this to select the chain of walls or lines.
And when I do that, if I hover my mouse over one of the walls and hit TAB just once, so I press the tab key and now it's highlighting all of those walls. If I left-click, it will actually select them. At this point, I can go in and make that adjustment for them to be set to the top of the parapet.

You'll also notice that I have the location line set to the finish face exterior. And that's going to be important because we will eventually change this wall type to something much thicker. At this point, it's a good time to save your progress.
Then, we're going to move on to the next video and create all the interior walls.
