Technology is ready for MBD, and so is SOLIDWORKS. Model-Based Definition (MBD) is the ASME Y14 series method for defining a product using its 3D model geometry as the basic dimensions in conjunction with the digitally associated 3D annotations as the geometric tolerance definition. Additional related Model-Based “X” exist (representing functional areas such as: Systems Engineering, Manufacturing, and Quality), but MBD births the product as it moves into downstream lifecycle processes.

Attempting MBE without Standard Parts in your Tool Box is just STUPID!
In order to turn your Model-Based Enterprise (MBE) or Digital Enterprise dream into reality, you must eventually come to the realization that a robust and best-in-class strategy for catalog parts is imperative. We’re talking about a certified standard parts library, not just something that Joe Blow modeled one day after lunch and a beer.
What is meant by “certified standard parts library”?
Ah, here we go. Gear specs. Orange tab. That was easy.
No, silly. Throw out your old paper catalogs. We’re talking an electronic catalog (or directory, if you will) from which an organization can download and reuse standard industry parts. For simplicity’s sake, think nuts, bolts, and washers. Your favorite rocket scientist has better things to do than dimension off-the-shelf bolts for the propulsion system.
We are operating at a stage in design and manufacturing where 3D models are used for direct tooling, or used to generate injection molds, but still need to be supplemented by 2D drawings for PMI (dimensions, tolerances and notes). In addition to creating extra work, 2D drawings are fundamentally flawed because the interpretation is limited to 2D, rather than real hardware which is 3D.
We see in 3D, We Should Document in 3D
I realize we have grown accustom to 2D drawings in the workplace, but these orthographic projections of 3D data are limiting both in creation of un-ambiguous product definition and will castrate the performance of high-tech manufacturing processes, such as Additive Manufacturing (AM).
So… what is on the engineering horizon, and how can you step out of the 2D inertia spiral of death (a little Halloween humor for you)?
MIL-STD-31000A is released, but now the creators are focused on pushing out the message of MBE. Vendors are developing great presentations that circulate around how their software products support MBE. And now, the original Model-Based Enterprise creators, have put together a slick new website. This information is all software tool agnostic.
