Join Shaun Bryant for an in-depth discussion in this video Using the DIMSPACE command, part of AutoCAD: Tips & Tricks.
- [Instructor] Welcome to another tip and trick in the world of AutoCAD. Now, what we're going to look at today is the DIMSPACE command. So we're going to be looking at our annotation. So we'll be using the Annotate tab up on the ribbon there, as you can see. Now, the DIMSPACE command allows you to apply a specific distance between consecutive dimensions on your drawing. Now, you'll notice we've got another new drawing for you for this particular tip and trick. It's called ANNOTATE_DIMSPACECommand.dwg.
As usual, you can download that from the website to follow along with the video. Now, the benefit you have with the DIMSPACE command is that it allows you again to tidy up all of your dimensions and make sure that they all look professional and neat and tidy on your drawing. Now, at the moment, everything's quite consistent. You can see the top line of dimensions there between the grid lines, and then underneath that, you've got another line of dimensions doing all the openings for the windows and the door. Let's zoom in on this top-left corner here, between the grids J and I, just here.
So I'm going to zoom in, and you can see there, I've got a 3050 which is between the grids and a 3532 from the grid line to the opening for the doorway there. Now, I want to make sure that all of these dimensions are evenly spaced. Now, I can do this one by one, piece by piece, or I can do it overall if I want to. Now, what we're going to do is we're just going to work with two dimensions so that you can see the process, the workflow, of how the dim space command works.
So, we need to make sure that we do a quick sanity check first. So I'm going to move away from the Annotate tab and go back to the Home tab. I'm going to jump over to Utilities here, and I'm going to use the measure command and measure a distance. And I'm going to measure the distance with my object snaps on, from the end of that arrowhead there to the end of that arrowhead just there. Can you see it comes up as an intersection, and it's 1461.65. That's because we're in the model space, and everything is full-size.
So basically, imagine you'd got a spray can, and you're looking down on the building in plan and you've marked up all your dimensions. Those would actually be 1461 millimeters, .65 millimeters, apart. So you've got to do that sanity check. Just make sure that you don't put something in like, oh, I want it to be 20, because in this particular drawing, that would be 20 millimeters in model space, and the dimensions would be virtually on top of each other. So, ideally, I think about a thousand millimeters, one meter apart, would work really well.
So just hit Escape a couple of times to come out of the measure command. Jump back to the Annotate tab on the ribbon, and we're into the Dimensions panel again. Over here, like so. I'm sure it's very familiar to you, so we're going to hit this one, Adjust Space, or, as it's called, DIMSPACE if you want to type it. So I click on Adjust Space, and it asks me to select the base dimension. Now, this is really important, because you've got to work out which one you want to be your base dimension. So if you look at those two dimensions that we're looking at, the 3050 and the 3532, which one do you want to be the base dimension, because that's where AutoCAD's going to measure from.
Now, ideally, my suggestion would be that I use this 3532 there, because we know that's a specific distance from the building, and it's a nice tidy distance from the building. So that's going to be my base dimension. I then select the 3050, like so, where I want it to be spaced, and obviously, I can select any other dimensions above that if I wanted to. We don't have any. So I just press Enter, like that. Now, you do get this Auto option. Be very careful with it.
It'll either be very small or very big, depending on how you're working in your drawing. We need to enter a value, so I'm going to type 1000, my 1,000 millimeters that we checked and sanity checked earlier. Press Enter, and that sits really nicely above each other. So they are now 1,000 millimeters apart, and I can quickly check that, typing D-I-S-T for the distance command. And I can just measure the first point there, like we did previously, down to that end section there, and you can see that's now 1,000 millimeters.
And that's down on the command line, and you'll notice it quickly popped up on the dynamic input as well. Now, obviously, I can work my way along all of these dimensions and tidy them up. What I'm going to do is I'm going to undo what I've just done, and I'm going to show you what would happen if we use the 3050 as the base dimension. So let's do that with the DIMSPACE again, up on the Dimensions panel there, and the base dimension this time is going to be the 3050, like that. Then this dimension here, I'm going to space like so, and then I'm going to press Enter, and I'll type in my 1000 again, and press Enter, and it moves the 3532 up.
So you can see, depending on which base dimension you select, it either moves one-up or one-down, so I'll just undo that now, like so, and we're back to square one again where all the dimensions are consistent, but they're not at that 1,000 spacing. So you can see that the DIMSPACE command is extremely useful. Again, it allows you to be consistent and have consistent measurement between all of your annotated dimensions on your AutoCAD drawings. And as you can see, it's really, really quick and easy to use as well.

Q: Why can't I earn a Certificate of Completion for this course?
A: We publish a new tutorial or tutorials for this course on a regular basis. We are unable to offer a Certificate of Completion because it is an ever-evolving course that is not designed to be completed. Check back often for new movies.
