I’ll continue editing the composite solid by moving and resizing the sphere. Pressing the CTRL key, I’ll select the sphere. A red, green, and blue gizmo displays at the center of the sphere. I’ll talk more about the gizmo in future posts but for now I’ll ignore the gizmo and select the sphere’s center grip.
Even if the gizmo functionality is turned off, the sphere’s center grip displays and behaves as you expect from your 2D experience with grips. Selecting the grip makes it hot and automatically enables Move editing mode. You can then select an OSNAP point on an existing object; such as the Center of the top of the cylinder.
The sphere automatically moves to that location. Selecting one of the sphere’s quadrant grips enables you to modify the sphere’s radius. You can snap to the quadrant OSNAP of the cylinder to automatically match the cylinder’s radius. Just like editing a circle in 2D right?
To verify that you snapped to the right point, thus creating a sphere with the correct radius, you can view the sphere properties in the Properties palette. The radius should equal 13 just like the cylinder radius we edited in the previous post.
Use the CTRL key to select sub-objects within a composite solid.
Use grips and object snaps to edit sub-objects.
