By offsetting geometry, we can save a huge amount of time and have offset it is again, choose that line segment.

## Creating offset geometry

By offsetting geometry, we can save a huge amount of time and have the ability to create slots and rectangular holes with a simple line sketch. To get started, I have a rectangle drawn here, on the top plane. And I'm going to go ahead and choose the Offset command, right here, from the sketch tool bar. Click OK, and now we've got the offset command active. I'm going to type in the size of my offset, I'm going to type in 1.0 and I'm going to choose any one of these line segments and it'll preview what's going to happen. So, right now, it's offsetting it both on the outside and the inside. I don't really want that. So go ahead and turn off bi-directional. I only want on the outside.

But I do want to make base construction, that'll make these original lines here construction lines and make the new shape out here one inch bigger. When you're happy with what you have, click OK, and there's my shape. Now, the offset is determined by this one inch dimension here, so if I wanted to change that, I could always just click on it and type in, maybe, half of an inch, and automatically adjust. If I want to change the original shape of this box. I can just drag that around and I can add dimension to the, to the inside controlling box or the outside one, either way. It's a real quick way to make some quick modifications. Let's go ahead and change it back to one inch.

And it's a great way to draw, maybe like a base plate that has holes in the corners. So I can grab the Circle command, drag some circles, put them on the corners here, add a quick relation that says all four of these are the same size, make them equal and maybe add a dimension to it. Quick way, quickly draw something. There's symmetric, and it gives you a nice lay out sketch to help build the design. Next if I go ahead and delete all this, if I start with just this basic center line and I start right above the origin here, I'm going to drag out a line. And what I want to do is make that origin right in the middle of that line so I'm going to hold on Ctrl and select the two, let go of Ctrl and choose make midpoint.

Then what I can say is, offset it is again, choose that line segment. This time it's offsetting one direction but I'd really like to, like to have it go both directions so I say bi-directional. And then I have this cap ends I can turn on, so if it's not on you don't see those, or you click on cap ends you can either have arcs or you can have lines. So I'm going to go ahead and choose the Arcs option, and then click OK. Now, I can define the length of that line with a regular Smart Dimension. I'll type in 3.0, and I can also change the size of the offset by changing this dimension here, so maybe I change it 0.5.

Everything automatically gets smaller. I'll change it back to one inch. And maybe add a couple circles, snap them right to those endpoints of that line, make them the same size by holding down Ctrl, choosing equal, and maybe even add a dimension to it to get a fully defined sketch, half of an inch, and there's a nice little, simple Link predesigned with really only one line segment, an offset, and a couple circles. It's a really quick way to design things. I also want to point out while we're here, we can use the offset with arcs as well. So choose a three point arc, come over here, draw an arc, and just place it on screen, and then again choose the Offset command, change my offset maybe to a quarter inch this time.

And you can see quickly I can drag this arc around, I can change the angle, and the offsets automatically follow along, and it's a really quick way to make slots or cuts into a part with really just one arc and one offset command, so really handy. The Offset command is a quick way to use existing geometry to create secondary sketch entities. This is a perfect choice for quick slots and basic clearance sketches.
