Question from Anonymous: How do you know to use these relations like evalgraph, trajpar, etc.
Answer: Consider using these types of relations and features any time you need to vary dimensions along a sweep trajectory. Google Trajpar for additional examples.
Question from Mark: Sometimes it's hard to remember the difference between ctrl and shift. Is there an easy way to remember which key to use? Is ctrl like "addition" and shift like "alternate"?
Answer: Think of it like they are used in Microsoft Office. If you want to select individual geometries, use the CTRL key. If you want to select multiple geometries, use the Shift key.
Question from Marvin: How do you capture both open and closed conditions of a living hinge in a single drawing?
Answer: Use a Simplified Rep for each state and reference each rep when placing the views in the drawing.
Question from Michael: How does one create a 3D spline?
Answer: Intersect curves, Trajpar with sweep, curve through points, are all options for creating 3D splines.
Question from Sharon: Can you use this technique for assembly operation cutout to get negative volume in assembly mode?
Answer: Yes, however, using Creo Flow Analysis is an easier method, or even using multi-body techniques.
Question from Theophile: Can you show again how to select the 4 edges of a square hole, please?
Answer: Curser over the first edge, then right click to pre-highlight the intent edges, then left mouse click to select them.
