In this class we will be using the Creality Ender 3 V2 Printer. Your life and my life will be easier if we are working on the same hardware. You can pick up your printer on amazon at the following link: [affiliate link]
amzn.to/3GaGn25
You will also want to stock up on some filament for your printer. I like the eSun PLA. Here is a link to what I am using:
amzn.to/3yXhYLz
The link shows you can get different colors. I like the orange.
In this lesson we will teach the fundamentals and foundations of 2D sketching in Fusion 360. The battle of Fusion 360 is won or lost at the 2D sketch level. Success at sketching in Fusion 360 hangs on being able to understand Constraints. Constraints can be your worst enemy or your best friend. By understanding what they do, and how to think about them, will allow you to master 2D sketching, and hence master 3D design.

I have never commented before on "the TH-cam" so this is special. Paul has an exceptional presentation style that suits me perfectly. In general I hate instructional TH-cam videos. Paul is a master teacher. He makes no assumptions about what you know, this is very hard to do. He does not waste our time with senseless blather. He is willing to even show himself making mistakes because it informs. I have held off learning anything in the Autodesk space because what their materials show is not relevant to me and so poorly done. So much instruction tells you what buttons to push and never make an effort to teach you how to think about something. My ignorance is being transformed and ideas are exploding in my head. I am so looking forward to lesson 6. For the impatient, Paul has other excellent 360 tutorials that come from a different internet archeological era but am so happy he is updating and targeting my e3v2.
Thanks for the kind words!
I second this.
I never commented on TH-cam at all. But seeing this tutorial to learn Fusion 360 easy and quick compared to the other not so beginner friendly and complex videos.
Mr Paul, I am going to Uni in a few months and rather having a class or something to teach me, your videos let it be Arduino or Fusion 360 is truly one of a kind. Thank you for all your efforts.🙏🙏
I third this 😂
Thank you very much for the lessons
Just curious, would’ve tried this but I don’t have the chance right now, does concentric constraint work for squares too? Just asking out of curiosity, don’t judge me 🌚
Just getting into 3D printing and I can say with all my confidence that this has been the best lesson by far on Fusion 360!!! I was about to "Die Trying" until I found Paul, now I have hope haha!
Paul,
A 76 year-old comm systems engineer here. I've been lurking around your channels for several years and watched as your teaching style matured and grew through the years. Thanks for two things. 1. For your efforts to teach to a broad audience in an interesting and entertaining way. 2. For keeping this old mind learning and much sharper than it would otherwise be.
Thanks for everything.
Wow, thanks!
Paul, I'm just getting into 3D printing and your tutorial has been very enlightening. This video really helped make sense of how to use contraints.
This is by far the best training video I have come across for constraints in Fusion 360. This is a long video but every second spent here will save you hours down the road in your 360 efforts. It is time well invested. Thanks Paul!!
Another excellent tutorial! As a Heavy Diesel Mechanic looking at going into mechanical engineering, this is a wonderful insight into the work flows. Thanks from Australia.
Excellent!
Lots of good info that usually beginners miss.
Bolt hole circles remind me of my machinist apprenticeship 30 years ago. One of the tasks to pass year 2 was to calculate, sketch and drill a given bolt circle usually 5 or 7 holes using just a scientific calculator for the trig. This was on a manual Bridgeport mill with no digital readout so we had to account for backlash of the table screws as well. I messed up a few before I got the hang of it. We were given an hour to finish. Now a modern CNC mill with conversational programming you can do it perfect in 5 minutes.
Really amazing how easy new tools can make things, but I really love the old school ways. I am not against using the new automated features, but think it is great is we still understand what is happening under the hood.
You are my hero! God Bless you. You taught me Arduino and now you are teach me Fusion 360+3d printing. You are the teacher I wish I had in highschool.
Super excited for this lesson!! :)
Absolutely loving these Paul, thanks so much for your great content!
Wow man what an awesome teacher you are 👍 from a total beginners point of view you teach everything so clearly & well, I'm hoping to learn angles & rounded edges in future videos, thank you 👍👍
Thanks Paul this will help me with that box lesson that you made 6 years ago I was having a hard time with the hinges
This really helped with allot of my designs, usually I changed a parameter and it damages something but now Im rollin with no problems!
Great Vid Paul. I Know I am a bit late as I had to manage my school work (that's just an excuse for my procrastination). But now, I will be taking these lessons without procrastinating (i am improving :D ).
Been watching a lot of F-360 videos but find this one with its strong emphasis on constraints has put e farther than the others.
Thanks Paul, much appreciated... 😊
Best teacher ever!!
The concept of 'designing in' relationship constraints between parts, makes it sooo much easier to modify later. Big lesson here for me. It reminds me of using variables at the start of code. Way easier to modify later. Fantastic lesson here ... Thank you.
Great refresher course for EEs!
This is a fantastic series. Thankyou for all the time and effort that you have put into this.
My pleasure!
Paul, you are a great teacher. I have been following you for years now. Looking forward to using all the knowledge you are giving us. Thanks
I cant wait for more of your excellent videos. It's so good to have someone sharing knowledge and time the way you do. Please keep up the excellent videos and thank you.
Excellent video. I completed the previous series but am enjoying the recap and new information. Thank you.
Thanks for joining this series. Know that these first lessons are reviewing some of the material from the other class, but I plan to take these lessons much further and deeper than the first series.
I made mistakes following along and then would see Paul make some of thos same mistakes and then how to fix - which is a bonus! I like that he challenges you to see if you can think how to solve a situation. Of course, pause and then attempt on your own. I will be going back over this tutorial just to make sure it's all cemented in the grey matter. Thanks Paul
Your videos have been awesome. I have experienced all the negative impacts of trying to learn that you explained in the first few videos. Your lessons have been so much easier to understand.
Thank you!
Constraints are for me either a best friend or worst enemy. Super important lesson, one worth watching again.
I always love when I can change a dimension, and nothing breaks! All thanks to constraints!
Absolutely!
Finally back from my travels and getting to these lessons. This lesson helped me immensely. Hoping to get better at this software - it sure is "touchy." I had to start over a couple of times to end up with the designs you had in the video. Thanks for the great lesson!
Welcome back!
Dear Paul, i can say that these lessons made me starting understand 360, I have to admit that i will passed them again and again until i am confident to work... I am watching 2 lessons daily.but again i for sure have to come back again when in need. I also would like to say that i have not found such any lessons smooth and easy understanding as yours, and i mean it. I am from the small island of Malta in the Med, and unfortunately not much help even from locals on 360. Big thank you again from my hearth.
Wow! So so good. I played with Fusion a while back and the person I watched did not cover what you covered in this lesson and last lesson and despite actually drawing something pretty cool I had no idea what was going on behind the scenes and therfore as soon as I tried to go off on my own I was lost. Thanks so much!
Thank you for these great lessons. I love how you teach this subject in a way that I remain interested and focused. I can't wait to learn more and start designing my own projects.
Great video again. Learned a lot about constraints today. Got started late in this series so this may already been pointed out: if you select an element and then type an x from the keyboard, it will toggle construction on and off.
As always , well explained tutorials. Thank you Paul
My pleasure!
Excellent! The first time I've seen constraints explained in a understandable manner!
Reading the top comment here made me smile. I have only ever commented on Top Tech Boy. Paul is simply worth the effort! Paul's style is slow, but very deliberate. Even with that comment, I have to pause to see the exact process to achieve the objective. So I appreciate the consistent reinforcing process that is used to teach those watching. I've repeatedly returned to TTB's channel for Arduino, Raspberry Pi, and Linux because of Paul's excellent teaching style.
Thank you Paul. This is great teaching, very pro. Thanks for you time on getting this to everyone. Best teacher I´ve heard
Just wanted to point out that, for example, if you want 2 lines parallel, and neither have any constraints or dimensions, after clicking the Parallel command, which ever line you click first is the "master" and the second line you click will move to accommodate it in order to satisfy the parallel constraint. So if your having issues with the wrong line moving when you don't want it to, this might be the reason.
You're a proper instructor, unlike many TH-camrs today. I really appreciate your traditional way of educating. It's quite refreshing. I hate to say this, but many young people today memorize techniques but don't really "learn" them. They are smart but are not learning. In fairness to them, they are overwhelmed with endless amounts of information. They jump from one topic to the next in minutes. But, the world needs more people learning from teachers like you, and less people watching silly cat videos.
great detection
Enjoying the lessons more and more - the fog is beginning to clear !
I so much like and appreciate you NOT editing out your mistakes, but instead when you do make them, showing us how to correct them too !
Brilliant - can't wait to watch lesson 7 😉
Glad you enjoy it!
Thanks Paul enjoying your videos!
Sooo good. The engineer-designer mindset. Constraints, constraints baby.
So glad to hear that your wife is feeling better and is at home. Your explanation of constraints clears up quite a bit of my fog. Just need to practice more. God Bless and keep you and your family.
Thanks Danny!
Thanks, Paul! This Constraint video was SUPER helpful!!!
Thanks! You are so kind, I appreciate it.
great series. extremely helpful...
Another great lesson Paul. Crystal clear as always! Blessings from my side of the world.
Same to you!
Another great video thank you! I wonder if you consider making any video series about robotic manipulators
Really like the pace of lessons, repetition of important things
Thanks Paul! Another lesson masterfully presented. Every detail as important as the last one. Your aim is to train us to master a skill and to foster independent thinking. I am still standing and ready for the next lesson.
My pleasure!
Thank you for this, Paul! I'm excited to get started in fusion 360!
great lesson for 3D beginners
I have to say thank you so much for teaching this series. I have been following along and am super excited to get my new laptop setup this weekend to start modeling. Episode 6 made complete sense regarding constraints versus dimension.
Excellent! This really was an important lesson.
I definitely learned some cool New things Today, a really big Thanks for that
This was incredible! Can’t thank you enough !
Glad you enjoyed it!
Designed a couple items following lesson 4. Everything keyed on dimensions. Using lessons 5 & 6 info will reduce time and enable more intricate designs!
I love your courses Paul. I have ben taking the Arduino course for a while, and decided I wanted to learn Fusion too. We've enjoyed messing with our printer, but TinkerCad only gets you so far :) But now I'm finally starting to understand Fusion360 (even if I still have a love/hate relationship with it ;) ). All that is to say, thank you for making such a great course.

Excellent lesson.
Everything very well explained. I hope everyone is on the train to move forward now. Thanks for teaching.
Its the Fun Train!
Great lesson. I love the useful examples in the end.
I loved the way you teach, making complicated topics very easy to understand
Thanks for liking
Great job!! Like always, so easy to understand and follow.
Another great lesson on Fusion 360 fundamentals. I think the difficulty will be in translating the idea of a design into the appropriate constraints between the parts of the design.
And the solution will be practice. Do all the examples I do along with me, and then do them by yourself. If you master these lessons, the future lessons will be easy and fun.
Wow. Awesome info. Thanks
Thanks for the lessons, I second David's comments.
BOOM, got it, thanks Paul
Thanks for another great lesson. Relational constraints over dimensional constraints will make life easier. Speaking of which, I can’t solder. Any video tips?
Impressive, bravo!
The sun is shining
it was extremely benifial for me sir
Wow this was an amazing lesson thank you for all you do to all the people in the world may God bless you
Thanks Danny!
Excellent presentation combining 360 with 3D printing. Please provide example of an internal groove as would be used when designing for an o-ring inside of the bore of a hub. Thanks
I Constrainting with you in this Korse My friend
Wonderful lesson, as usual with the most excellent Paul
Glad you enjoyed it
Hi Paul,
i love your lessons, and i have learned a lot from your, and looking already further to the next lesson from fusion 360.
i struggle still a little bit with constrains, especially with making a hole for an 25p D-connector.
the connector is fully black, and i can move no parts from it, everything is locked, but i have no lock.
But i still try further until i have solved this problem.
I have bought a PRUSA i3 MK3S+ KIT, and this printer works perfect, and print without cosmetic faults, and also de dimension's are in spec.
Maybe it is a good idea to extent the course fusion 360 with a few lessons moving parts.
It looks me great to see how gears are moving etc.
This looks me a good tool to check your design before starting to print it.

Great lessons on fusion 360 and 3d printing. I was thinking that a neat practical project would be to create a fairly simple raspberry pi case. This would also be a practical application to use digital calipers as they would be required to make the case to fit the raspberry pi properly to align mounting holes and accommodate all the usb connectors and the other connectors.
Yes. Particularly if we had a little project where you made a portable device, in a slick case. Also, thinking at some point we will want to get Pi Zero W which is just like the pi but very small. HOpe we can do some portable projects.
This was great. Thank you
Thanks!
Wow, thanks! Really appreciate the support, it means a lot to me.
i appreciate you
I'm committed to getting through all of these lessons, my calipers arrived today as well. I got held up for a few days when my Fusion 360 software started crashing on startup. I updated everything I could think of including drivers and still could not run the software. Eventually I found there is an environment variable that can be added "QT_OPENGL" with value "software". I assume this just moves rendering off the GPU and on to the CPU likely with a cost to performance although these aren't super sophisticated designs so I assume it will be fine. I'm running an i9 with 3080ti so I am a little disappointed that the Fusion 360 software is having trouble with GPU rendering.
Maybe try ask a question on stack exchange? Using software rendering does not sound right even you have a nice CPU
GREAT JOB!
The sun is coming out.
Thanks for a great video. Will you be covering the raspberry pico w
Not for a while. Lots of Fusion lessons and lots of raspberry pi lessons still to make. Hard for me to do more than two series at a time.
10:00 Remove constraints to move an sketched object
Remember the song by Jimmy Cliff "I can see clearly now". This session was a real insight into using Fusion 360
thanks, I really do love this stuff.
Brilliant, understanding the concepts more than just randomly drawing, the skill sets can also then be applied to other software design applications , Freecad. How's the property coming along with the planting of the trees and the gardens?
Things are well here. Lots of food coming in from the gardens and the trees.
Thanks
Wow, really appreciate that! Thanks for the encouragement.
@@paulmcwhorter hi I’ve been following your tutorials on fusion 360 closely. One think I haven’t been able to understand in constraints is how do you place circles in a sketch at equidistant points in every corner of a rectangle. Could you please direct me to the relevant video or help
hello paul !
Hi Paul ..... question, can i print a sketch on a normal paper printer, as a drawing ??
Another point, can i find somewhere a keyboard shortcuts to easily select functionality of the Fusion, i do it for Line, Rect, Circle, Dimention, Extrude, i guess there is much more
for example CTRL+Z for Reverse editing ..... I am on a Linux system many years, so keyboard, command line edition is my lovely part to speedy access to a system, work flow, etc.
Please, say few words about it, thank you
My mind just blew up
In a good way, or a bad way?
Do 3D printers prefer metric measurements?
👍 for the TH-cam algorithm
Hello Paul Lesson 6. Cannot get the constraint to appear at about 11 minute mark. Any suggestions?
Hi Paul. Love the course. Can anyone help me. At 32.00 the drawing of 2 circles, i have locked, when i put the lines in and constrain with tangents, it does not lock, i am following your drawing step by step ! Any Ideas ?
EDIT Ok, I think i found a way, after constraining lines with tangent i then have to grab end of line and move till an X appears on circle, then it constrains the tangent with a coincedent. So it seems the tangent cant lock because the length of the line can still be extended passed the circle !
Hello Paul, do you have some solutions to the prints warping off of the bed? I've had this problem with a few prints now. Thanks.
A lot of it comes down to getting a really flat bed, cleaning the bed, and big prints that are wide and tall are more likely to warp. After those things, play around with the bed temperature or print on a raft.
Hello Paul, do you know what is the difference between Fusion 360 and Autodesk AutoCAD?
Fusion has more user friendly gui.
Hi all, Question, in 2019 I built a Arduino and I now need to pull the info from it so I dont have to rebuild it from scratch. I am a advanced beginner. At that time I was was cut and pasting other ppl code. So can you load from a Mega to the computer. i know it complies it but is there a way to decomplie?
you can not get the code back. It was compiled, and then zeros and ones downloaded to the arduino. You can not undo it. Code is lost.
Anthony. There is an article in the arduino forum entitled "How to rip code off an arduino". I haven't tried it but it may be worth a try
Shazam!
59:10 "Guys that are just hacks go in and start drawing"
Thanks! Really appreciate the help.
🙏🙏🙏👌👌👌🖖🖖🖖🖖
Very good lesson, but still i have problems.
Tried to draw a 25p D-connector. choose a fixed point from orgin. use a 3point rectangle.42,52x11,41. 4 circles diameter 6,7.2 side lines from 10 degrees. use tangent for the 4 circles. then the lines are all black but no lock. i have tried it on many ways without any success. who can help me out?
grtz Frans
click around on it and see what part can be moved. Some part you have either not diminsioned, or not constrained. Poke around on it till you find what moves.
@@paulmcwhorter Hi Paul,
thanks for the fast reaction. All lines around the connector are fixed and black. i think it is something whit the 10 degree lines on both sides from the connector but also that looks ok. it makes me crazy. tried already 4 hours and 25 tryouts.
Hi Frans, You don't say why it is not working so I posted a short vid on how I would do the sketch. th-cam.com/video/ZP3mGFz0obM/w-d-xo.html
Let me know if I did not get what you are trying to do.
Solved after 25 tryouts.
the solution was.
first make the sketch.
then add dimensions.
then add the sketch to the origin point.
i will never forget this
Just to let everyone know if your drawing gets too complicated our free versions of the Fusion 360 software will deliver an error message and you will not be able to continue.
DrDave, in such cases it is usually not that we are using the free version, but we have created an error. You have to think of fusion 360 as if you were writing a program, and each step you do is a line of code. You can have a bug in your code. If you are doing a lot of backing up, undoing and re-editing prior sketches, you can introduce errors. If you get in a mess like that sometimes it is better to just start over.
@@paulmcwhorter Ok. That is a great point. I will try that. Thanks!
@@paulmcwhorter The error message was that my document limit had been reached, so I clicked on My Editable Documents, and they numbered 10, which is the max for us to have. That’s when we get the message. I thought it was the complexity of the drawing.
Also, not such thing as a silly cat video.
