Sizes of dynamic components changing

[jon bondy]

There are two dimensions for a component: that which is visible on the screen (Type A), and that which Sketchup displays when you click the component (Type B). Sometimes the latter is significantly larger than the former.

I start out with a dynamic component that is, say, a cube. After I use it for a while, the Type B volume increases with empty space. My equations in the DC assumed that the two dimensions (Types A and B) would be the same, so the DC stops functioning properly.

Can anyone explain to me how to manage the Type B dimensions of the component?

Thanks!

It sounds like you are moving the cube away from the axis of the component. The bounding box normally hugs the component but if you move the cube or rotate it within the component then the bounding box will expand.
