A suggestion - when calibrating use a longer "line". In this case instead of using 1 cm on the ruler, use the 10 cm. This would reduce any error introduced in the clicking process by a factor of ten.
This is great, but I would add a note. To improve accuracy, if at all possible use a scan rather than a photo. A simple document scanner will work with a lot of flat parts. Second, if you are using a photo, you should try to correct for lens distortion before using the photo for modelling. You would be surprised how much our photos are distorted by lens curvature. I use Darktable which is able to correct for a wide array of popular lenses, and is free-open-source.
This 1000%. Not only will a scan get rid of distortion from the lens and the angle, but it also gives you precise measurements. Generally if you set your scan to 600 dpi, each inch will be 600 dots. Setting your scale to pixels will give measurements accurate to about 0.01 inches. Check your scanner by scanning a ruler too.
You might consider drawing only half of it precisely and then mirror your drawing 😉
What about using graph paper as the background.
Oh not a bad idea
Thanks a ton for your FreeCAD videos, I've been trying to get started with some 3D design projects and I've had a hard time getting oriented. Your last tutorial was excellent, would love to see more!
Don, this is a fantastic intro into some of the functionality of freecad. Looking forward to trying this out for some brackets. Loved the way you explained the process, very concise and mentally digestible. Again, thank you.
This is an excellent how to, thank you!
Excellent Video Don! Keep em coming!
this was super helpful.
For this video, I must subscribe. Thank you.
Cheers bro!
Hey Don your videos have been helping me out alot, I am fairly new to CAD and I am having trouble with a arched line, the 2d piece I am sketching has 2 straight lines but the 4th being the top is curved and raised 2mm at the center how do I go about this?
life saving. thank you. something like this in blender3d?
B spline is a good way for angles/curves. Allows for more fine tuning. I think constraint tangent would work as well but don’t quote me on that. Just some things I use. But I’m no pro by any means
Wow cool video, thanks! And, could you show us how to prepare model for the laser cut, if we need file like 2D blueprints in dxf or something like that format
This was a great video. I too want to use freeCAD for 3D printing. Thanks!
U r just awesome!!!
Super.
I do laser engraving with Co2 laser and fiber laser. Would this program help with me making stuff
let'ssss gooo, i'm learn a lot from this
((( ABSOLUTELY ))) PERFECT TO MY NEEDS !!!!! AWSESOME !!!!!!!!!!!!!!!!!
👍❤️
You could also just change view mode to wireframe and you would see the image behind without changing transparancy
Cool video, however somewhere between creating the inner pockets and actually hitting the create pocket button, something doesn't work on my end. Instead of rectangles, I've drawn circles and no matter if I hit create pocket or create hole, it just doesn't do what I see in your video. I've even tried to follow every step by step and I get to this point and it just doesn't work. Any ideas?
I have the same problem...it won't create the hole/pocket no matter what I do. Is there an update to this video?
always do half and then mirror it :)
for me it says "wire is not closed"
I don't have create poly line??
ooops I found it
I know this is only a demo... But you probably could have tape down the paper part to make it flatter...
Great video . K i s s
This video should already have 10x the views. YT algorithm sucks unless you make jackarse content
Notice how anything of any REAL educational quality doesn't blow-up but ignorant hack vids that have zero real life use get millions of views
If you're here .. I hope you understand ... YOU, yes you .. are far few in-between on this planet of intelligence seeking more input (short circuit)
It's impossible to take a photo without perspective and lens distortions. Without some king of algorithm to deal with these distortions this method will be very inaccurate.

this vid is crap freecad no longer has image workbench soo nothing in this video applies to those of us who just downloaded it and thus i still cant crop a part from an image to manipulate or rework or 3d print my free cad has all different icon's also so maybe do another vid on the freecad the rest of us have. I tried to find that crap icon you clicked on to make part a 3d model but i don't see that either it must be from one of the 500 workbenches available freecad is boo &%@@!! ive spent a week trying to crop part out of pic i still cant even put measurements for the part dimensions boo sh !worst cad and worst teaching vid
