However, over the past couple of years, I have spent a little less time drafting than usual and so I decided it was time for a refresher.

Take a look at some of my recent work here.Īt the start of Q2 this year I decided that as part of my continuing education efforts I would work towards ASME’s Geometric Dimensioning and Tolerancing Professional (GDTP) senior level certification. I have created GD&T annotated drawings for many of my clients over the years. I was fortunate in that I was exposed to the short-comings of conventional plus/minus tolerancing and the need for GD&T very early on in my career. However, after a couple of weeks, I had grasped the basics of GD&T and could navigate proE comfortably enough to start pumping out well-annotated drawings.

If anyone has worked with pro/ENGINEER Wildfire 5 or earlier… its not the most intuitive software (I recently took nTopology’s nTOP for a spin – totally different experience – I will be writing a post about my experience soon). My mentor gave me his laptop with a pro/ENGINEER licence, told me to get my hands on a copy of ASME’s Y14.5-2009 GD&T standard (I still have it), and left me alone with the instruction to learn both. Luckily, back in 2012, before I graduated from the University of Toronto, I did some contract work for my future engineering mentor who began the process of remedying some of the gaps that a formal engineering education seems to create. The only GD&T training I remember in university was arbitrarily sticking datum targets onto a drawing of something I modeled in SolidWorks. By providing uniformity in drawing specifications and interpretation, GD&T reduces guesswork throughout the manufacturing process - improving quality, lowering costs, and shortening deliveries.” – ASME My Experience “GD&T is an essential tool for communicating design intent - that parts from technical drawings have the desired form, fit, function and interchangeability. What is geometric dimensioning and tolerancing (GD&T)? More specifically, choosing functional datum features for your parts.

In this post I will briefly go over some GD&T examples – datum features. GD&T Examples – Datum Features… Functional Datum Features
