SubD for organic modeling in SketchUp – Using the Crease Tool

This SketchUp tutorial will teach you one of the most important things you need to know to do organic modeling with the SubD extension.

Intro to SubD –
SketchUp SubD Forum –

In yesterday’s video, we talked about using SubD to subdivide our models into more organic shapes. I’m want to talk just for a minute about an issue that I struggled with when I first trying to use this plugin.
What I kept running into was that I was getting more subdivision than I wanted.
For example, I saw the example people showed of subdividing two faces to create a smooth curve, but my results kept coming out like this.
At first I couldn’t figure out why, but then I watched a 3D basecamp video where the instructor used SubD, and I noticed he was using the crease function to modify which faces stayed in place.
This is a vital thing to know if you’re going to work with SubD that I originally just kind of skipped over.
Go in and use the crease tool to select your points and lines in your group. An important note for this in SubD is that you can crease both lines and points to stay in place.
You can select multiple points by holding shift and clicking on those points, or multiple lines by just selecting them before you activate the crease tool.
Once you’ve done this, it shows you a little slider. This slider allows you to set the amount of crease on your object. A setting of 1 is 100% crease, meaning that line will not move when you subdivide your model. A setting of zero means that it will subdivide 100%.
Just remember, working with SubD is a very trial and error process. It’s not like laser machining or drawing a line down to a ridiculous level of detail. It’s more like convincing SketchUp to give you the shape that you want.
Remember that with a tool like this, there’s going to be a lot of trial and error involved, so just be willing to try a lot of different things, and also be willing to go to the SketchUcation thread and ask questions. The actual developer of the extension hangs out there and is very very helpful.
I’d love to have you leave a comment below, let me know if you’re using this extension, what kind of tutorials you’d like to see for it, even if you feel like it’s worth the money. One of the things I love about this channel is that it’s a conversation with you about SketchUp.
