Ron,

I used to do the profile approach as you did, but over time (particular in Alibre) learned that it painted me into corners. Using the stacked primitives approach has proven to be far more robust when it makes sense and leads to a more easily updated model. For out production Tuff Nut t-nut models, I use a table driven part. Doing that you map columns in a spreadsheet to named dimensions in your model. Only way to make it work well for me was the stacked approach. It is pretty cool, want a new size. Just enter some numbers on the spreadsheet or using the table in the program and then select activate. The model changes to the new size. Using my existing model I could have done a new size this way in about 1 minute.

I do use the profile method you illustrate at times, but as I gain experience, I find myself using it less and less. Definitely use it more for lathe parts and then revolve the sketch.
