- What is a loft modifier? Where are loft modifiers used? How do we use loft modifiers?
In this tutorial I am going to be showing you how to use the various loft tools within FreeCAD! These include additive loft, subtractive loft, and utility loft. I try to go into as much detail as possible, while keeping the video short and simple, and also explain a little about 'facebinders' in the draft workbench.
I’m also still trying to deliver the best quality videos I can, so this week I’ve made the sound clearer by adding a foam cover to my mic, and fixing a fan in my computer case, where the bearing had failed causing an awful racket!
Thank you for taking the time to watch my video, have an awesome weekend! :)
For those looking for extra resources and reading material about lofts, follow the links below to the FreeCAD wiki pages, which will provide further information about what I have spoken about in the video:

This just saved me hours of work trying to recreate a waveguide (horn) , I spent hours yesterday drawing it with datum planes on weird angles and all i needed to do was draw the cross sections every 50mm 🤪
Thank you Andrew. I find your tutorials simply the best for me. You are slowly turning me into somebody who can actually do something. many thanks.
I'm just coming on board with Freecad after 4 years of Fusion 360. Your videos are jammed packed with info. So much that I have to stop and rewind a lot before it sinks into my thick head - 😂 Keep up the good work and cheers from Canada!
Hey Lewis! I'm glad you're finding the videos useful! No judgements from me for the thick head 😉 I'm planning on doing a blog/write up which will hopefully accompany my videos, is this something that would intrest you? Thank you for your support and welcome to Freecad! 😁
Andrew CAD I would be very interested in any writeups you make on FreeCad. I've been picking through the wiki but it's a cumbersome way to learn the program. A couple of the very active guys in the forum have come up with pdfs and I've been reading through those with much more success. One thing I'm having trouble with is the various coordinate systems and how they interact. I was very productive with Fusion before they gave the hobby world a glimpse of the future with their crippling efforts and now I'm back to being a bumbling noob again with FreeCad, but I'm not giving up. 😉
@@lewiscobb7817 wonderful! I'll try to get some form of site set up in the coming weeks! I understand what you mean, I'm more of a visual learner and find videos to be the best form of absorbing information! So if I can create write-ups which feed you information but with tons of visual graphics then it's a win win! Hopefully all of this will help turn you, and others into FreeCAD pros! 😁
Thank you for this video, by watching it, I was able to cut the inside of a trapezoidal shape, while maintaining the same thickness of walls on the entire perimeter.
I looked for how to achieve this, and it was your video that allowed me to succeed. Thanks again.
Very good, show what is possible and then I work out what I need to do. I like this approach.
I'm glad you enjoy the video style! My aim is to create content that allows you to create your own ideas and parts, so it's great to know it's working 😀 Thank you for watching 😁
Just found your channel. Don't know why I haven't earlier. Clear and to the point. Very good content and good promotion of a good open source software. Been using FreeCad for a long time. Recent development has made it a very good and useful tool. Thanks for sharing!
Hey funkysod! Glad you enjoyed the video! Definitely a great bit of software, with an awesome community! 😁
Extremely helpful tutorial. Answered my question in the first five minutes. You'd think it would be easier to make a tapered octagon to replace a broken handle (needed to match the existing aesthetic). None of the other tutorials were useful, but yours gave me what I needed. Thank you, sir.
Fantastic video. You are epic. This was very helpful and greatly appreciated.
Very useful I liked it and I will watch the rest of the videos.
"random spawn of evil" hit me way too hard!
Great tutorials. Thanks.
No problem Chris! 😀
Really cool! Easy to follow, keep on!😎
Thank you Sascha! 😁
Neat video, thanks.
I love/hate the rapid pace .... I need coffee now!
Hi Andrew, really useful tutorial. I currently have an issue similar to your last example of what not to do(unnamed4). However the sketches are not complex at all - a small triangle going 90deg to a slightly bigger triangle. The loft is linking the wrong corners together creating a funky geometry almost as if the loft is inverting/folding in on itself. Just wondering if there any controls or changes to the sketches I can do to fix this?
Thank you
Very good, very fast. That took a lot of rewinding lol
Hey Teun, I'm glad you enjoyed the video! Hopefully the speed wasn't to much of an issue! 😊
I really struggled with a double loft ruled profile. Basically a piped profile with a shape as the profile crossed inner and outer walls at certain sections. I spent days trying to rectify it. In the end it appears Freecad joins profiles in the order you create them and not whether they are both inner or outer walls. Hope this helps someone.
Hi Andrew,
Just stumbled upon your channel, I have started to learn 3D modeling using FreeCAD. Can you let me know how you are rotating your sketches?
Very good video
One problem
Some of us have poor eye sight, We find it very hard to follow the small an fast moving pointer. Is it possible to make the pointer bigger. This will help from the pointer disappearing.
Thank You
Hey Pieter! I certainly can make the pointer bigger, I shall do that for the next video. Thank you for the feedback 😁
@@AndrewCAD Thank you very MUCH
Super work! I'm glad this came up as suggested for me. You don't have enough attention for this good work- how about a collaboration?
Thank you so much! I would absolutely love to do a collaboration! 😊
@@AndrewCAD Nice. I have my email in the description of my videos; feel free to drop me a line and we can swap some ideas
Been trying this all evening, and my additive tool keeps saying recompute failed. Any help with this would be great.
Shift who? 1:04 when i try to enter the value, the camera angle changes...Not usual in any kind of cad/Bim software.
Hello. In the start, making the slot, you said shift something, prior to establishing the extent of the slot, and I can't get what you said, nor figure it out. 'shift h' is what you might have said, because the slot then became constrained horizontally, but I get no reaction trying the same. Could I be missing some protocol to make my keyboard work? When you next specify shift h, again nothing happens when I do it. I am using the latest freecad. Trying again helps, ignoring the shortcut. Really exhilarating for some of it to work. I look forward as never before in cad
9:00 I think you can use the thickness tool to convert a surface into a hollow solid.
I'll give that a go tomorrow and see what happens :)
@@AndrewCAD I tried it , the thickness tool gives an error: "the object is not a solid"
@@paulg3336 The thickness tool is equivalent to shell command in Fusion 360. It shells out a solid and creates a wall of desired thickness. What you want is the 3D offset tool in the Part Workbench.
GODAMIT!! Why can't i add a Simple cone to an surface wihout the programm crashing?
Thank you . Change the title ( 3d modelling freecad) yoi will have more viewers . Good luck
Thank you for watching Nabil! I shall change that now, thank you for the tip! :)
Too bad freecad loft cannot blend g1 or g2 to the ends
you speak fast and quiet but the lesson is very clear
100%
Great job, but I'll just ask a little slower
I need a cnc milling machine. only suckers buy door handles
why is cad so damn unintuitive.. we live in a world with VR, this should be as simple as a kid virtually picking up blocks from a toolbox and slotting and squishing them together and having it be able to calculate physics like the stress and torque and springy energy stored in each bit and use that to model itself so it can do real time IK on itself... why am I having to pick the right order of sketches with names like 'Sketch" "Sketch1" and "Sketch2" not got time for that when software should be touchy-feely interactive and intuitive o.o
Thanks, but too much words (
Sound is too low.. Very disgusting 😤
