Integration with CAD system

Dear All;

My customer needs to procure a CAD system, and integrate it with SAP. So, my question is, Does SAP has a ready made CAD system that can be used in Form work, Scaffolding design, and if not, how can an external CAD system (MEC CAD) integrated with SAP? , What are the procedures and what are the integration points that can help the customer doing its business with SAP?

Thanks for your kind support.

All the best,

Mohammad
