Join Shaun Bryant for an in-depth discussion in this video Using the OFFSET command, part of AutoCAD: Tips & Tricks.
- [Instructor] Welcome to another AutoCAD tip and trick, where we take you through the commands and the features in AutoCAD to make you that little bit more productive and effective when you're working in your autoCAD environment. Got a nice new drawing here for you. It's called MODIFY_UsingTheOFFSETCommand.dwg. You can download it from the website, as usual, to follow along with the video. And as usual, my drawing titles tend to give away what the tip and trick is. We're going to look at using that wonderful offset command in autoCAD.
Now, we're going to zoom in on the floor plan in the model tab on these offices, here. So get them nice and central on your screen, like so. You'll notice there's an extra grid line down here. We'll go to that one in a little moment. So let's have a look at the offices themselves. Now, we want to make those offices a little bit bigger. What we're going to do, is we're going to utilize the offset command. We go up to the home tab on the ribbon, into the modify panel, and there's offset right there. Click on offset, and come into the drawing area.
Now normally, by default, you've have the word through there on the dynamic input. Obviously, I've put a value in, and autoCAD has remembered that value, which is 1,500 millimeters, or 1 1/2 meters. I'm just going to press enter to accept that. If you've got the word through, just type in 1,500, and off you go. It's a metric drawing, by the way, so we're working in millimeters. If I press enter now, it asks me to select the object I want to offset. So if I hover here and click on that line there, then if I move up or down to show the direction of the offset, I'm offsetting 1,500 either side of that line.
So if I come down here, click, that's offset by 1,500. If I now offset this line and do the same again, can you see, it's giving me the wall width because I'm using the other line. Like that, click there, and there's my wall offset. It's giving me a nice corridor now, running alongside those offices. I just press enter there to close out the offset command. Now that's all well and good, but I might want to display these particular walls on a different layer.
They might need to be a new layer, or an existing layer. Now, I'm going to cheat a little bit. You'll notice up in the layers panel at the top of the screen, that our S-GRID layer is the current drafting layer. I'm just going to undo what I've done with those extra walls. I'm just going to undo that step there and lose what I've offset already. Here's a little trick that I really like with the offset command. If I click on offset again, come into the drawing area, and then right click first, I can select layer. And I get the option of current or source.
Source means that it maintains the layer that the objects are on. If I go to current, it uses the current drafting layer to offset. So now it's prompting me for the offset distance again. I'll press enter to accept the 1,500 or type 1,500 in. Let's do that offset process again. If I select that one there and come down, can you see now it's on the S-GRID layer? How neat is that? So I might have a new layer that I wand to offset to, and lo and behold it goes onto that new layer like that.
It's really kind of cool, isn't it? Really useful. I'm going to undo that again, now. And what I'm going to do is utilize this little grid line down here, this one. I'm just going to do a little offset now, and I'm going to going to do a thing called offset through. So I go back to the offset command. I right click layer. Remember to go back to source layer, not current. And then I'm going to specify an offset distance. But instead of typing in a distance, I'm going to right click and use the through option so I can pick the distance visually.
So here's the object I want to offset, that wall line there. Then is asks for a through point. I'm going to use that intersection of the grids, and it puts that line there for me. Now, what I can do, is I can then just hit escape a couple of times to come out of the command. If I delete that line, you'll see that it's offset through that intersection, and placed the line on the grid line where I wanted it to be. I don't need to keep that grid line, or I may keep it, I don't know, it depends. Depends on how I'm working in the drawing.
But you can see that the offset command is a really, really useful command. You can control layers, you can control where you offset through, and you can control the distance of how far you're offsetting a line or an object, as well. And don't forget, it's all visual now as well. Once you've selected the object to offset, as you move the mouse around, you can see which side of the object you're going to be offsetting on in context with the orientation of the autoCAD object 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.
