The "Dincel" system is not yet a material option for PlusSpec. Dean from PlusSpec may have more information on this and whether they are planning on incorporating it in PlusSpec.
I've just had a look at the Dincel website and although proprietary it is essentially the same as numerous other panel/block/concrete systems. As such, and with the unique flexibility of PlusSpec, this could be easily modeled through the option of creating your own material. I have done this for other similar materials and it works well.
A note here... Although you could easily model this system and have accurate takeoffs etc you would need to be familiar with the engineering aspects of the system and have your design signed off or checked by an engineer. PlusSpec allows you to produce fully modeled and costed designs but does not account for the "engineering" aspects of your building solution. As an example although PlusSpec can model all your roof truss needs you would still need a truss manufacturer to produce the final correctly signed off solution for it to be acceptable by building authorities. This is also true for any general architectural modelling system.
