At the 0:57 mark I mention that I have auto constraints enabled, I'd like to also point out that I have 'Auto Remove Redundants' enabled. If you don't have that enabled you'll run into a redundant constraint error around the 2:24 mark.
Yep noted this as I couldn't get it to work. Unaware that autoremove must be turned off, I found a way to move on. I set a horizontal distance between the center of the large semicircle and the X axis to 0 mm. Then everything ended up right and FreeCAD was happy with green everywhere. But thanks for the input that autoremove must be on. Your videos are so good, one learns those little details...Cheers
Dude, you are an EXCELLENT instructor. Coming from a guy who made a living teaching CNC machine\programming\MasterCAM, you have a real talent. Thank you for this, with all sincerity.
I have attended many classes and courses throughout my 25 years in IT. Your are clearly among the top 3 instructors/teachers. Your style is so relaxed, logical, to the point and just so easy to follow. Amazing work :) Please create more tutorials for us
I've been trying to learn FreeCAD from a ton of different RUclips videos. Yours have been the most concise and have really helped get me moving in the right direction. Thank you!
After watching the 3 first videos (I'll wait watching number four until I am familiar with the stuff learned until now) I can't thank you enough, as this is the first videos and/or tutorials that has explained FreeCAD in a way, where I actually think I can use it and most importantly, in a way that make me want to use it! Your clear and comprehensive style is just excellent! Thanks a lot!
Hi, thanks for a tutorial that is possible to follow for me, that not have american/english as first language. Many other are way to fast to follow, so I just get frustrated. I just have to step back and forward a few times so your tempo is just at the limit as I'm a total beginner in free cad. Nice and easy projects, but gives a huge lot of learning in short time. Thank you, and please don't speed up the tempo as the other. Regards, from the north.
I would love to know what's the best pointing device, mouse - trackball - flat pad.....and what would the navigation settings be? Also thanks very much, I appreciate all the time it took to make all these vids. Gary
Great videos!! Thank you! But can someone explain why the fillet at the end did not throw an error when the fillet meets the edge of the circle? This seems to happen in other cases, I know freeCAD doesn't like when fillet lines touch other lines. I made this part on my own first before watching the video and the way I went about it ran into this error.
Very nice video. thanks. As a newcomer it just came to my mind, is this method of constraints (relative addressing) is a must do or it is just another method of drawing in contrast to absolute addressing? I mean I can address everything with respect to the origin or coordinates..
Great videos, I've been following along and I'll repeat the drawing just to keep practicing. But for some reason my create external geometry feature gets weird, like it shows me a red circle with a line going through it when I try to apply it to an edge. It used to work but it just up and stopped working. I'm sure I'm doing something wrong but I don't know what it is. Any suggestions?
Hi Danny, If the points have a constraint holding them together, you can think of them as being stacked. For example: If you had two points in your sketch with coincident constraint applied to them, the points will share the same X and Y position. Even though it looks like a single point on your sketch, under the hood it's actually two distinct points in the same position. I hope that answers your question!
@@dannyperkins4220 You can go to Edit -> Preferences ... -> Display From there you can change Marker size: to some other value to make the markers larger.
Yooo! How can i set constraints across a mirrored sketch. i have base sketch and y reflection, so now i want to change the displacement between the reflection and the original. so basically the correct way to interact between two sketches of the xy plane. sorry if u already did this
Question for you, when you're doing your polyline to do the body of the first shape right after the circle, the first portion comes into a constraint of a straight line. I will arc around and do my next straight line, then a vertical to close the elements. As soon as I attempt a constraint coincident, the whole body turns red and I get a redundant constraints of four. What is this caused from?
Hi, thanks for commenting! I just spent some time recreating this sketch to get a better idea as to why this happened. First off, the reason it didn't happen to me when I was recording is because I had 'Auto Remove Redundants' enabled. At the 0:57 mark on the video I mentioned that I have Auto Constraints enabled, but I should have pointed out that I have Auto Remove Redundants enabled too. I'll pin a comment about this so others can find the solution if they run into the same problem. As far as why constraint number 4 (the horizontal constraint on the top line) is redundant, here's my understanding of it: Due to the tangential constraints between the end points of the arc and the end points of the lines, the line angles are affected by the angle of the arc. Moving the center point of the arc changes the arc's angle, which in turn affects the angle of the lines. When we apply the coincident constraint between the center point of the arc and the sketch origin point, we're constraining the arc's angle to exactly 180 degrees. This cause the lines coming the from end points of the arcs to be perfectly horizontal. At which point the horizontal line constraint becomes redundant. To visualize what I'm trying to describe, you can delete the horizontal line constraint from the top line, as well as the coincident constraint on the arc center point, and then drag the arc center point around the sketch. You'll see the angle of the top and bottom lines changing as a result. When the center point of the arc is position near the origin point of our sketch, the lines become horizontal. Hopefully that makes sense!
@@JeffCAD1 that's it! The auto constraints is what I missed. I noticed in your video that the same horizontal line you mentioned, goes away... so the system auto removes the redundancy. Very grateful for your reply! I'm trying to learn FreeCad to teach my boys so we can buy an Ender 2 V3 and they can print some cool stuff. Again, appreciate you.

Thanks again. I followed your steps in this project, and it was a good refresher, even though I'm using the most recent version 1.
Thank you very much for these tutorials. These are a great help
Superb set of training videos. Thanks so much. Im struggling a bit on creating curves on 2 axis but ill keep trying!!
Great videos! Concise and well thought out. Will be practicing all four lessons. Looking forward to more videos. Thanks👍👍
Keep making more!!!!! These are so helpful!!!
Another great one you are the best freecad teacher I have found thanks

When setting a diameter constraint for a radius of 20mm, given can you just type "20*2", and similar calculations?
Yes, that's right! FreeCAD allows you to use mathematical operators when entering constraint values.
Have a like and a comment. All hail the algorithm. SuperfastMatt.
Love it!
These are soooo helpful. Sub'd!
Thnx a lot
