Why spend a lot of money making an error prone program when you can have reality simulate it for you? This is a problem I had at my last job, actually. We'd spend a lot of time on simulation that was kind of accurate but still need to do a fair bit of rapid prototyping to make up for simulation deficiencies afterwards. For simple stuff like a prototype jig to hold equipment mockups can be faster to make out of rough cut materials instead of spending 2 weeks making everything fit in a CAD program.
