Here the point can be defined, depending on the situation, at which the component may be stretched.
Dialog box section Stretch point
The position of the stretch point can be selected from the pull-down menu or defined by entering values (relative/polar).
Dialog box section Reference point
The reference point specifies the point from which the scaling is to take effect. For example, the default setting Top center has the effect of anchoring this component at the fixed point and stretching it downwards in the Y direction. The required position of the stretch point can be selected from the pull-down menu.
