Video: Using the Offset tool to create outlines

Another way of adding detail to your models is by using the Offset tool. Now what this does is it creates an offset of your edges to create another outline. So it's a way to create outlines insets that sort of thing. So let's go ahead and clear out our workspace here by selecting and deleting that person and let's start with the Rectangle. So I am going to go ahead and just draw a simple rectangle and then get kind of a top-down view of this and let's take a look at the Offset tool.

Using the Offset tool to create outlines

Another way of adding detail to your models is by using the Offset tool. Now what this does is it creates an offset of your edges to create another outline. So it's a way to create outlines insets that sort of thing. So let's go ahead and clear out our workspace here by selecting and deleting that person and let's start with the Rectangle. So I am going to go ahead and just draw a simple rectangle and then get kind of a top-down view of this and let's take a look at the Offset tool.

The tool can be found under the tools menu, Offset or the letter F and its right here on the toolbar. So when you select it, the icon changes and all you have to do is left-click within a face and drag and you can create an outline, very-very simple, very straight forward. And then also you can create measurements, so if I want to create say a 1 foot inset I can just type that in and it will go ahead and step to that.

Now once you have all of this extra detail then you can use it to Push and Pull, so, for example, I could push and pull this into a more complex object. Now one thing I want to show you about the Push Pull tool is how it works with convex or curved surfaces. So I am going to go ahead and select all of the stuff and delete it and let's go ahead and create another shape. So in this case I am going to use the pencil tool. So I am just going to go ahead and draw a line here, but I want to create kind of an inset here I am going to create kind of a dent in my surface here, I am going to hit space here.

And then at the top I want to create an Arc. So I am going to go ahead and select the Arc tool and make sure I drag that out along the green axis and there I have got a surface. When I select the Offset tool, you will see that yeah I can offset some of this. So if I wanted to I could offset that, but if you pull it too far you will notice how the lines start to intersect and overlap and that creates condition that SketchUp really doesn't like.

So if I were to keep it here kind of close to the edge here it wouldn't work just fine. But if I go a little bit too far so they start overlapping what happens is SketchUp tries to make those into surfaces but you're going to get things that are overlapping and kind of weird edges and that sort of thing. So you have to be careful when you use this sort of tool, not to get those overlaps and sometimes if you're doing things with very tight tolerances you may get minor overlap, you just need to be careful.

So let's take a quick look at how to use the Offset tool and more for practical way. I going to go ahead and open file called DecoHouse_00 and this is kind of a half built Arc deco house. And let's go ahead and add some additional details to this house. So we are going to go ahead and start on the top edge here. I want to create porch here and in order to create a porch I need to kind of create a wall or a bit of a railing on the building here and we can use the Offset tool in order to do that.

So I am going to go ahead and select Offset, hover over that phase and then create an offset. How big of an offset well we can type in that number, let's say I wanted 8 inch offset I am just going to hit 8, hit enter. Now if I were to pull the shape into an actual wall, so if select that and pull that up you will notice that I have some additional detail right here that's probably not one I want this to kind of go straight up against that wall so I need to come to fix that before I actually pull that into the walls.

So I can do that very easily, all I need to do is take my Pencil tool, zoom in here from this endpoint and make sure I am snapping along the red axis and just kind of draw that line all the way through and do that Again, here. Then I can hit my spacebar, go ahead into Select mode, select this line and delete it. So now I have this straight up to the edge here and let's go ahead and select that phase and pull it up. And let's go ahead and make that say a 3 foot wall so I am going to make that 36 inches and there we go, very-very simple.

Now let's do something that's a little more complex, let's go ahead and build some windows and the offset tool is really handy for things like building windows. So I want to make some windows along the front part of this building here, so each one of these little sections I want to put a window in. But in order to do that I need to create enough detail to put that window in. So, I am going to go ahead and go to my Line tool and let's us just go ahead and I am just going to start by snapping to mid-points. So what I am going to do is just draw a ring of lines around middle part of this from part of the building.

So Again, I am just connecting midpoints, so go midpoint to midpoint, midpoint to midpoint, midpoint to midpoint. So now I have a line all the way around that building. I need another one for the top of the window so this is going to be the bottom part of my windows. I am not worrying so much about where those lines are we are going to go ahead and move those into place later. So let's just go ahead and repeat this operation so I am just going midpoint to midpoint here and I'm just Again, sketching in the outline that I need to create these windows.

So once I have all of this in place then I can start working with the detail that I've added. So I am just going to go ahead and hold down the Shift key and select these edges. So once I have these edges selected then I hit M for move, go into the Move tool and then just drag those down. So now I am kind of opening up the space that I am going to be putting in Windows. If I want I can do the same on the top so I am going to hit spacebar, go back into Select mode, Shift+Select hold down the Shift key and then move or M for move and then just move those up along the blue axis.

So now I have a bunch of spaces here each one of these is going to be a Windows. So let's go ahead and start using the Offset tool to do that. So all I have to do is select a face, go to my Offset tool and then offset that. Now I need to figure out how wide of a window frame do I want. Let's go ahead and just type 2 for 2 inches and hit enter so I have a 2 inch window frame, kind of a thin window frame but it should look good for this house. And then all I have to do is select the next one, go back to the Offset tool and this time just like with the Push Pull tool all I have to do is double-click and it will Again, put in my 2 inch window frame.

So Again, so spacebar select, F for offset Double-click, spacebar to select F Double-click and we can just do that all the way around. So now I have space for all of these windows. But then Again, I need to actually create depth for the window frame. So I can do that using the Push Pull tool. So all I have to do is just hit P for Push Pull, let's go ahead and push that in for 2 inches, hit enter, same thing double-click, double-click, double-click and all I am doing is just double- clicking on all of these and it should just default to that 2 inches I typed in, very-very simple.

So now if I want to actually make these into holes, I can either do one of two things I can keep the surfaces here and make them clear glass by using a Material which may be a good thing to do, or If I just want to make them hollow I can just select all of these and hit the Delete key and that will go ahead and just create those windows as holes. So we have an option in doing either way. So those are some of the ways to use the Offset tool and as you can see it's a very handy tool and I am sure you'll be able to use it a lot.
