"Generally, the good practice in defining sketches/sections is to prefer constraints over dimensions, and to prefer surfaces as references over edges/vertices."
This statement came from the PTC R&D team in the context of a discussion involving constraints of a sketch and the resultant feature. I was having difficulty capturing the design intent to produce the desired outcome in the geometry of the part. The desired result was achievable but only by implementing some unorthodox sketch constraints. The geometry is proprietary so I will not be posting it here.
Has anyone had training on Creo since the intent manager has been deployed as the only sketch environment, and if so do you recall this paradigm from the training? Are there any other resources that explain in detail the algorithms in intent manager with examples of outliers and solutions?
The closest thing I can find on PTC.com is a tutorial titled "Understand Construction Geometry Theory".
I am looking for some PTC or 3rd party material that delves into the foundations of this statement. It is so fundamental to the capture of design intent it would surely be part of introductory training with examples.
