Okay sir..

thank you sir for the note, we are eternally grateful

Thank you sir

Very Comprehensive!

Technology explained!

sir, i downloaded a fusion 360 video were the instructor was modelling a plastic conduit that has a box ,lid and 2 screws. i was able to preference, set my units in mm,create a new component and also to turn on my origin. but i got to a point were the instructor talked about “extrude” and that was were i lost it, as he did not properly explain how to extrude. thank you.

Extrude is the most basic way of creating a 3-D object. The first thing you need is a water-tight closed boundary in 2-D. Extrude is a command that will create a solid with your closed boundary as a section. Try and do the 2-D of a tuning fork. I have shared the my tuning fork sketch. This is easy to extrude. Typing “Q” brings the “Press Pull” menu. You can extrude after changing the “One side” there to symmetric.

Thank you sir.

wonderful topic and looking forward to the next class

Please don’t wait for the class. Create the tuning fork first.

Done.

Sir how do I turn off the grid if I want to work without viewing it

In the “Grid and Snaps” tool – just above the timeline, uncheck the Layout Grid checkbox.

I practiced creating the tuning fork on fusion 360 and I am now very excited about this course, looking forward to the next class.

Very good. You can learn a lot in company of your mates. Invite someone to share your data and see if they can offer ideas. Just go to the Data menu, in “people”, you can invite people using their email addresses.

how can i apply engineering mathematics theories to fusion 360?

The first thing is to KNOW your relevant mathematics. The second is to know the basics of Fusion 360. If you understand how 3-D coordinate systems work from the Euclidean point space, it can help your parametric modeling. If you understand tensor analysis, you will, for example, see that Fusion 360 simulation gives you Von Mises stress. The Von Mises is the square root of the second principal invariant of the deviatoric stress tensor. You cannot even begin to understand what this means until you know what the invariants of the stress tensor mean. Now, a 13 year old JSS3 student can learn Fusion 360. A carpenter and a tiler can also learn. A design engineer at Boeing or Airbus can use the same software. They will be getting completely different things done with it.

Any level of Fusion 360 mastery will likely be sufficient to fetch you your daily bread. The more engineering Mathematics you know, the more you can get out of it.

In addition to 3-d parametric modeling, Fusion 360 does simulation (that is embedded NASTRAN – an industry major player in Finite element analysis). It also does design optimization where you use the results of the simulation to get the best design based on prescribed objectives. It can do nonlinear material analysis; you have no chances of even knowing what is going on there unless you understand nonlinear constitutive theory such as the difference between hyperelastic and hypoelastic materials. That is nonlinear elasticity! There is visco elasticity and anisotropy. There is so much programmed into these tools. Fusion 360 can do modal analysis. You can get the mode shapes of a vibratory system and understand the natural frequencies. These are the eigenvalues and eigenvectors of the governing equations – Engineering Math!

We can go on. Just don’t get me started on such a question as this! Go to the website of the top engineering schools in the world: They do much more math than we do here! It is not a coincidence!

ah dey laugh

very well done sir, i hope to learn more from your lectures
