Mapping curved objects

From: Google SketchUp 8 Essential Training

Video: Mapping curved objects

One issue that may crop up in SketchUp is texturing curved surfaces. Typically SketchUp likes to apply flat images to flat surfaces, but if you have a curved surface there are ways to apply texture to those surfaces. So let's go ahead and start by creating a curved surface. I'm going to go ahead and clear up my scene and I'm going to take a Circle and let's just create a two foot circle and then select the top of this and use the Push/Pull tool to pull out a five foot object.

Mapping curved objects

One issue that may crop up in SketchUp is texturing curved surfaces. Typically SketchUp likes to apply flat images to flat surfaces, but if you have a curved surface there are ways to apply texture to those surfaces. So let's go ahead and start by creating a curved surface. I'm going to go ahead and clear up my scene and I'm going to take a Circle and let's just create a two foot circle and then select the top of this and use the Push/Pull tool to pull out a five foot object.

So now I've a cylinder that's two feet wide and five feet tall. If I wanted to apply a texture to this we could do it one of two ways. Let's go ahead and start by Importing an image here and I should have one of my Chapter 7 folder called SoupLabel, and make sure I have this selected as Use as texture, click Open. And when I do you'll see what the issue is when I try and map a flat image onto a curved surface. You'll see that wrapping it around is not as easy as you think it will be.

So if I click on this and scale it what happens is that it only applies it to that one face, here let me go ahead and turn on View>Hidden Geometry and you'll notice that this particular curved surface is actually made up of a bunch of flat faces that are smooth, but when I applied the texture in that way it only applied it to that one face. I'm going to go ahead and turn off Hidden Geometry. Now there is another way to do it and that's just by allowing SketchUp to kind of figure it out by itself.

SketchUp will try to map a material to a curved surface as best it can, and that's usually the best way to let things happen, it's probably the best workflow. So I'm going to go into Window> Materials and let's go ahead and Create a new Material, let's just call it Label. And for Texture I'm going to use a texture image here, I'm going to use that same image in my Chapter 7 folder called SoupLabel, Open that up and hit OK.

And once I do I can select that and just paint bucket that onto my surface. If you Notice we've got this a little bit better. It's actually wrapping around which is half a battle there, but our scale is off. You notice that this is 1 foot, but we actually have a 5 foot high material. So what I can do is I can make this 5 feet wide, but that's still not wide enough. So if I make it 10 feet wide then that should do it and everything else should fall into place.

And when we do that actually gives us a 10 foot high soup can, which will make a nice advertisement or something like that, but you can see how SketchUp will try to apply a material to a curved surface. Now this is kind of what depend on the type of surface, simple surfaces like the cylinders will probably be a lot easier than more complex surfaces. So your results may vary. If you need to do a more complex surface you may have to go to a third-party texture Mapping tool which are available for SketchUp, or you may need to do your texturing in an outside application such as, 3ds Max, Maya, or Blender, but for basic surfaces you can kind of let SketchUp figure it out by itself and it should do pretty well.
