"Designing joints with the proper thread engagement length can help ensure that threads don't strip or yield. This can prevent parts from failing on the assembly line or in service"


This falls right into the DFM/A area and re-emphasises the need to check designs against standard guidelines as early as possible. The benefit of doing things right the first time is derived not only for manufacturing / assembly but also during service.

Again, this is not applicable only at the part level but also at the assembly level where things get a little more complex. For assemblies, stuff like clearance, fastener engagement, fastener accessibility, interference, bolt projection are critical. I bet while reading this you can think of a lot more depending on your products.

The problem till now was that it is humanly impossible to keep track of all these checks manually. This is exactly where DFMPro helps in automating the design validation process against guidelines and other checks which are simple to define but difficult to implement primarily due to the error-prone nature of a manual process.

DFMPro helps check designs easily and quickly right within the CAD environment thus helping achieve not only better quality but also reduced cost and improved time to market.
