Multiple Len(x) in dynamic components

Hi is there a way to input more than one Len(x) in the attributes definition for dynamic components? I want to create a footing where i need to define two different lengths for a trapezoidal footing shape.
Thanks

LenX (and LenY,LenZ) define the ‘bounding box’ of the Component. To accomplish what you need, you would have to divide the shape in multiple shapes.
