Hi Rod,
Every component has an insertion point. This point is the component's axes.
Normally, the axes is placed at one of the component's corner.
Use this point as the focus when placing a component to your model.
When you place a component and the insertion point seems placed in the middle of the component. Most probably, the axes is still at the component's corner, but you view it from the opposite side.
Insertion points in Dynamic Component behave differently though.
