I recently installed and started teaching myself the Creo suite of tools. I needed a replacement for AutoDesk Inventor. I’ve posted the finished product of the tutorials for building a piston/ piston shaft. I would like to reach the same capability I previously held with Inventor. For those of you not familiar with Creo, Wikipedia offers this:
Engineers/pilots will notice, on my model, the abscence of wingtips and the exact airfoil is reproduced as best as possible for being lofted from drawings. This drawing was intended as low fidelity to facilitate a proposal. It meets those requirements.
Completing the Creo tutorial required some breakdown between both the text and the videos provided. Completed exercises are shown below.
A piston created in Creo (Creo Beginner Exercise 1)
A crankshaft to emphasis patterns and simplifying (Creo Beginner Exercise 2)
Two way ranging and Doppler systems are summarized. Differenced measurements or “differencing,” is explained. For additional explanation on differencing see Penn State’s course for Geospatial and GNSS professionals (https://www.e-education.psu.edu/geog862/node/1727).
There was some difficulty with projecting the slides to the screen so they have been added after the lecture was recorded.
The environment and relativity effects on radio and optical communications are introduced. One-way range measurement systems are introduced. GPS is provided as an example but it still applies to GLONASS and Galileo. Two-way range, Doppler, and differenced measurements are considered next.
