CAD and Design Training

I am leading CAD for team 6036 and during Power Up I (and a bit from other members) CADed our intake system for the cubes, because it had a lot of machined parts. Our machining lead found it very helpful to have drawings so there were not as many mistakes and he was doing a large amount of the machining and next year more members will probably be machining, so it is even more important. My team has (almost) decided to do some sort of workshop over the summer/fall. I have been thinking a lot about how to teach Autodesk Fusion 360 to other members of my team during this event, also how long should I expect teaching of CAD to take. Would 6 weeks w/ 3h or so per week really be enough. I guess it would be depending on how much I teach. What level of depth should I teach, just basics, or go through everything (Drawings, Model, Animation(just exploded views) and sculpt (would not find this at all helpful for FRC), simulation and Render)

A secondary question is how other teams teach design. The team that I am a part of has members from several schools. The school that I go to has a great PLTW program, but a majority of the team is from another school without a good Engineering curriculum. I think that "design/engineering skills" are important. What do you think? Of the things have been learning this year in PLTW Introduction to Engineering and Design what would be worth teaching in another workshop. (Statistics, Technical Drawings, Tolerances, Parametric Design, Fasteners, probably something else I am forgeting)

I seem to have a similar question to this(https://www.chiefdelphi.com/forums/s....php?t=159430), but I don't think I am supposed to bump that so I thought it would be better to start this

Thanks in advance for suggestions.

Re: CAD and Design Training

We finally started using fusion 360 (previously used CREO but we switched due to the fact that we were using a demo version) to CAD up all of our robot parts before we machined them. We loved using Fusion 360 at first because we could login and share files through our accounts, but our lab's computers are locked meaning we cannot update them without administrative access. Anyways, without updating our computers we can no longer share them unless it's emailed.

Anyways, working with Fusion is quite simple. We had the father of one of our students (uses Autodesk Inventor) come in and show the students where some of the tools are and how they work (lines, polygons, circles, extrude, pattern, hole, text, etc.) From there they were given parts (2x1 predrilled vex tubing) to build. When they are finished with that we brought them to VEXs website and taught them how to import CAD files from the internet before checking their work with the original file. We trained in about 10 people within a week and a half (3.5 hours/afternoon) to where they could CAD up individual parts to the robot. (Note we also spent about one week on learning how to make spreadsheets and assemblies).

From personal experience I would suggest teaching the basics with sketching, assembly, and drawing, then giving them projects to build, assemble and make drawings.

Re: CAD and Design Training

We don't have a real "formal" cad training system.
We teach a handful of students what they need to know to be productive during build season. We usually have a few experienced members who help out the new ones.

It helps if the students have some basic cad-drafting skills, if they know how things are made, and if you can show them an actual "thing" they're designing.

We primarily use Inventor for build season to design our robot and parts to fabricate or machine.

Last summer we used Fusion 360 to get a whole bunch of students introduced to CAD. They were able to download it for free on the school MAC's (which you can't do with Inventor) It's "similar" to Inventor but lacks special things like threaded hole features (which we use when designing actual parts). But it got them thinking in the right direction.

Re: CAD and Design Training

See if your district has a subscription to Lynda or the like (or even YT videos, Autodesk has a set of Fusion/Inventor tutorials for FRC applications,) so the students can learn at their own pace for the basics.

Ok, thanks for the feedback. Did the mentor go through each tool ("this is the circle tool. 3 different types... and you use it like this. Shortcut is C") or just kinda just go through all together. Seems like your mentor was able to teach really fast... did he just did the very basics. I was going to go through every tool, maybe I shouldn't, just main tools for frc (we make almost everything from extrusion.

In the latest version of fusion 360 the fusion team added a threaded hole feature. But still not in the drawing environment, so it still lacks that to inventor. I have added a suggestion to the fusion team to add this feature in the future.

Interesting... I was just assuming that I would teach, but I guess our programming team is thinking of not teaching it, but just give people youtube videos

I'm also wondering on good ways to teach design, as next season I'd like to grow our CAD to more of a design based team in addition to CADing parts for fabrication and for drawings. I know there are teams who aim to finish all their CAD early in season, and then build somewhat based off that, and I think even if we don't fully do that, being proactive and knowing how to design so we could work in more conjunction with build team would be great.

I introduced Autodesk Fusion 360 to a group of High School students this year. After installing the software on their computer, I pointed them to the excellent collection of Fusion 360 Youtube tutorials by Lars Christensen.

I suggested they first watch an entire capsule, then go back and replicate Lars' actions with all the pauses and fast forward/backward as they wanted.

With nothing more that the first three videos, they had mastered the basic CAD concepts and were off to the races.

After teaching them the basics with a Slicer application, they were then off to the 3D printer making their CAD realizations into something they could touch and manipulate.

The lesson I learned through this exercise... Never underestime a motivated high school student with the right tools...

I am a high school student and that is about half of how I learned CAD... other half, the transferable (between programs) from engineering program at my school in inventor. But I mostly watched Lars' videos and played around... making smaller projects. One of the reasons that I wanted to teach was that I thought it might be only way to teach because it would get them to learn, and not just goof off, because our team is really good at that

Re: CAD and Design Training

The biggest thing to remember. Make sure your students are well versed in understanding typical FRC build processes (how to use tube, fasteners, gussets, welding, standard COTS gearbox and wheel options, etc) before you throw them at CAD. It will pay dividends.

I am still a freshmen and really that is not my specialty... but our build capt should do a lesson on bushings/bearings and some other usefull frc stuff... Good idea, thanks
