Possible to split the outer panel in two layers with different materials

It's now possible to split the outer panel of a sandwich wall into two layers with different materials. This is done in the element definition.

Figure 1: Wall Definition 

Two new outer panel options divide the outer panel into an interior layer (closest to the insulation) and an exterior layer, allowing the use of two different materials in the outer panel.

The combined thickness of the interior and exterior layers will always match the total thickness of the outer panel. Additionally, the material of the interior layer will define the overall layer type of the outer panel.

On the shop drawing, will the layers be shown in the material table, in the sections and in the 3D solid.

By default, the layers will follow the outer pane, but it's also possible to define the "Sublayer Boundary" in the endcap. This sets how the interior layer should behave.

With these two new layers comes a range of new data that can be shown in the shop drawing by adding any of the following attributes.
