Join Shaun Bryant for an in-depth discussion in this video Rotating with Copy and Reference, part of AutoCAD: Tips & Tricks.
- [Instructor] Welcome again to AutoCAD and another tip and trick that will make you that little bit more productive, that little bit more effective, in your AutoCAD working environment. So, we've got a nice new drawing to look at. It's called MODIFY_RotateCopyReference.dwg and, as usual, my tip and trick drawing titles tend to give away what we're going to do which is we're going to look at the Modify panel in AutoCAD in the Home tab on the ribbon. We're going to look at the rotate command and the copy and reference sub-commands in that rotate command.
So, you'll notice in the drawing we have a few little additions to the drawing by way of furniture. So, you'll notice over here we have a circular table and a chair and we have a sofa with a very weird angled line going through it which looks a bit strange but we'll figure that one out in a moment. Now, I'm going to zoom in on the table and the chair first over here in what looks like sort of a refectory kind of area. So, I'm just going to pan. Get that nice and central on the screen. Now, what we're going to do, is we're going to rotate the chair around this circular table using the copy part of the rotate command.
So, I'm going to select the chair like so and I can go up to rotate here in the Modify panel and click and then it prompts me for a base point. Make sure that your object snaps are on and use the center snap of the table like so as the base point and then you'll see obviously that our chair is going round and round the table. Then, I right-click and use the copy sub-command there on the menu and you'll see now that I've got a copy of that chair rotating and the original stays where it is. The rotation angle is going to be 180.
Press Enter and you've rotated that chair around the table creating a copy leaving the original behind. Now, that's great and, if I want four chairs, it's even slicker. It's really cool. So, let's click on the two chairs this time. This time I'll right-click on the mouse and go to rotate on the shortcut menu. Same base point. Center snap of the circular table and, as I move now, can you see that I've got two chairs moving because I selected both. Right-click again. Copy on the shortcut menu.
Rotation angle of 90 this time and I've now got four chairs equally spaced, 90 degree increments, around my 360 circular table. How cool is that? Really quick and easy. Let's just pan across now to that weird sofa thing with the line going through it. Let's have a look now at the rotate reference option as well. I want this sofa to be at the angle of that line in the halfway area of the building. So, what I do is I select the sofa and I'm going to cheat again.
I'm going to right-click and use rotate here on the shortcut menu. The base point is going to be there. That endpoint of the sofa where it intersects with the line. I then come away from the sofa, right-click and select reference and now here's where it gets really clever. I pick on this point here like so. Second point here and then, as I come down to the endpoint of the line, it all lines in with the line. Make sure you get the endpoint, snap and click. Our sofa is neatly aligned.
I delete the angled line. I don't need it anymore and my sofa sits nicely at that angle in the halfway area of the building. So, as you can see, we've updated our furniture using the rotate copy and reference tools in that Modify panel on the Home tab, on the ribbon.
