You can apply Lineweights to specific individual objects in AutoCAD. So, what we're going to do here is we're going to apply some Lineweights to some of the lines that we've actually drawn on this drawing. So, we're going to select these lines here that make up our little square. So, 1, 2, 3, 4. Do the same below, so we're going to go 1, 2, 3, 4. Now when it comes to Object Selection you'll notice I'm positioning the little square on the crosshair over the object I need to select when I click. That little square there is known as your Pickbox. As long as it's over the object when you click it will select the object. So what I'm going to do here now, again, look: Pickbox 1, 2, 3, and 4, and then 1, 2, 3, and 4. I'm also going to select this line here: 1, 2, and this line here, 3, 4. So, all those objects now are going to have a different Lineweight applied to them. Now, you do this in your Home tab at the top here, and it's your Properties Panel here, and you'll see here there's your Lineweight Option. Click on the down arrow next to By Layer there, and you'll see the listing of all the Lineweights you can use. I'm going to go for a Lineweight there of .35. I click on it, the objects are still selected so I hit Escape now to deselect, and the drawing doesn't look any different. Now why is that? Why would that be different? Because we haven't toggled our Lineweight to actually display on the screen yet. That is down at the bottom of the screen on the Status Bar. Lineweight is here. If I right-click over it I've got Settings there for Lineweight as well. So what I can do here is I can set my Lineweight Settings for Millimeters, Inches, Display lineweight, the Default Lineweight that I want to use, my Displace Scale, and so on. Now the Default Lineweight is always .25 millimeters in a metric drawing, so that's why all our lines at the moment look consistent. As you can see there, though, I can set Default Lineweights, I can Display the Lineweight if I wish. I'm just going to Cancel that for now because all I want to do is Show or Hide my Lineweight. So, I come down here and I click on LWT here, and notice my Lineweights now appear on the screen. They are displayed because the LWT Button on the Status Bar is lit blue. If I now click on LWT again, notice they disappear again and go to the Default .25 millimeter Lineweight. So, if I now click on it again you'll see they're displayed. If I click on it again you'll see that display is turned off. Now, how do you check what Lineweight an object actually has? The first thing you do is you select it. If I click on this line here you'll see, if I look up in the Properties Panel here it's at .35 millimeters. That's because I've changed that Lineweight on an individual basis on that line. You can see that there. So, what we can do there is, if I click on similar objects you'll see that they all show as .35, and I know that they've all got a .35 Lineweight. If I click on an object that hasn't got a .35 Lineweight, notice it goes blank, because it can only display the one. So if I click on that line there, if I hold down Shift and click on it that will deselect it. Notice the 35 comes back on the Properties Panel. Also as well, if I right-click now with these objects selected it brings up the Shortcut Menu, I can select Properties here and the Properties Palette will appear and the Lineweight there is telling me that it's .35. I can click on that down arrow there and I can select a different Lineweight if I wish. So as you can see, Lineweight and the ability to turn it on and off are extremely useful for highlighting objects on a drawing. So if I hit Escape now and switch Lineweights on, you can see how quick and easy you can set it up to make objects display and be more prominent on your drawing.
