Working with “Sticky Geometry”
In this section, we will talk about “sticky geometry.” What is sticky geometry? Why should we be concerned about it? And, most importantly, what does this have to do with Groups and Components in our SketchUp models? Let’s spend a few sections discussing these questions.
What is Sticky Geometry?
All versions of SketchUp follow the same basic rules that we covered in the last chapter. Those are as follows:
- All edges are straight lines between two points
- All faces are bounded (surrounded) by edges
- All faces are two-dimensional (flat)
There is another rule that we need to add to the list, which has to do with the way geometry interacts when edges and faces intersect:
- Geometry in SketchUp will interact with the geometry that it touches in either of the following cases:
- Both geometry objects are in the same group
- Both geometry objects are in the same component
- Neither geometry object is in...
