- Welcome to part 11 of the total beginners course to FreeCAD 0.20. Today we are learning lofting workflows which include the fundamentals of a loft where we learn and share tips on creating smooth transitions, lofting to a point, open and closed profiles and closing a model after a loft. I will also share how to modify existing lofts, make open surface lofts solid, and how to create a skeleton fr easy placement and modification of profile position.
This course is aimed to teach the fundamentals of free CAD understanding the basics but delivering via teaching you different workflows.
We aim to teach you freeCAD in a practical way.

I really appreciate the time and effort you're putting into this series. Everything is explained very well and I'm finally beginning to understand CAD.
That's is great to hear and thank you for the feedback. I'm constantly monitoring to make sure I try to cater for everyone's needs. Thank you for following and great to see your getting an understanding of what is a complex and unlimited subject area
I think it would be helpful to name the sketches (and sometimes other features). It's good to get beginners into the habit since it makes complex models much easier to navigate.
I like your didactic style.
Because you build on previous knowledge in a way that a novice like me can follow the process, and most importantly, can reproduce it.
Especially the very nice slow voice (I don't know the correct English idiom to say this without offending, which is absolutely not intended) is so much better than the ADHD-voices in other channels (where they talk too much and say too little).
Very well scripted tutorial! Thank you very much.
I appreciate that! Great feedback thank you. Believe it or not, none of this video scripted. 90% of my videos are taught around a concept and I just explain it. I find if I script something I end up taking like a robot. I know what you mean about the videos which are two fast. I have seen a lot of tutorials where the teacher seems to have had may too much sugar. You see this a lot in Blender tutorials . I have some videos were I have gone to fast and viewers have mentioned it, so I try to go slower as youtube has the option to speed up the video. Thank you so much for commenting. It's great to get feedback of how I am doing.
Agreed, but I slow Mango down to 50% LOL ;-) He sounds like One of the Guys at my Flying Club at full speedd!!
Another Great tut Mate!, I am starting to anticipate some of your procedures. In the Ruled Surface I got a weird shape but resolved it by Reversing the Surface Orientation (which I learned from comment in the previous Ruled Surface tut.. I've posted this as it may help another New Chum like others have helped Me. I'm an older Guy and I can see a way ahead modelling my RC aircraft. Thanks for being so Generous with your knowledge.
Thanks so much for sharing your progress, great to see your progressing. There are quite a few using freecad for rc aircraft so you will see an number of my videos have that theme that can be applied to that area. Thank you once again.
the new chum with the same issue happens to be me and it worked fine! Thank you
Thank you for this whole series. This has been very informative as usual.
Very informative tutorial, MJ...thanks!
Excellent
Thank you
For hull designing - this is the payoff vid! Thanks so much!
Great to hear, thanks for the comments 😁
complex material explained with expert skills. I get better every time I watch your great video materials that boosts my ability to navigate and use the workbenches.. A great journey on discovering the world of FreeCad where I am concerned :)
Thank you for such a nice comment, it fills my heart with joy each time I read them. Thank you so much, so pleased I am helping people learn. So great to give back what I have learnt in my years of CAD and design.
I feel well versed in the basics most of the time, currently working though your lattice and curves workbench videos, but coming and checking out beginner courses still teaches me quite a bit. Getting into the nitty gritty of lofting, especially the process of mapping a sketch support after it's been created is something that always confused me so I found more complicated ways of doing these sorts of moves but in a far less elegant manner. Thank you for your excellent videos on this powerful software.
Thank you for the feedback and kind comments, it's great to hear people are really liking these tutorials. I have so much more to share.
really glad i've found your tuts! thanks for this, enjoying the ride here. by far i'm having a hard time differentiating the additive pipe to sweep. i find the additive pipe tool much easier to use.
Glad your enjoying. I agree the addative pipe is so much easier to use compared to part wb sweep as I find the steps where you select the path for the sweep in part workbench a bit jarring and your left feeling that you need to do another step before selecting OK.
Fantastic, very good.
Glad you enjoyed
Another awesome video, great to see the viewership is increasing too! keep up the good work
Thank you, I hope all its going well with yourself over in sunny oz
map mode is OP
What i needed right now! Appreciate!
Great to hear
@@MangoJellySolutions How can I give thickness (2-3mm) to this loft structure which is created by your method?
@@ardacobanoglu703 You could create your loft as a shell and use the 3d offset tool. Or you could use profiles that are made of an inner and outer wall ( think of the profile of a hollow pipe when you cut it in half)
@@MangoJellySolutions Thank you for your advices! I tried the 3D offset tool but it didn't work due to complexity probably. But than i tried your method in your mouse video with gordon surfaces and worked!! The distances are not quiet same but anyway
Great - this has been a great help. Fantastic series of videos for an old bloke learning new skills. Designing a boat like structure so suited very well. When created as a solid I used the thickness tool to give me my hollow boat. To attach anything else to this (including inside) I assume I make the complete structure a compound and work from there? Keep up the good work.
Glad it helped and thank you for including what you are using it for. So for attaching you can use componds or if you want it as one then you can boolean the elements together. Don't forget about assembly workbenches either. That's another option if you want to keep components separate.
I know how to use it few CAD Programs like Inventor, NX, SolidWorks,etc (with normal function for regular person) :D Thank you so much for this tutorial. I love this FreeCAD is very usefull and when you know few features its possible create whetever you want. I have only one Question. Exist for this cad some type of PLM software for some network database? Thank you
Sounds Good.! LOL:)
its very easy to learn from your videos Thanks for your efforts! I have small doubt, I made a ring with an angle it is perfectly okay but when I want to expand or cut open it to see how I can make it out a sheet metal I'm unable to find any tool that can do that in FreeCAD Please help!
With a little frustration and effort, I am able to get a loft to work. Once that is finished I need to put a hole all the way through I can't get that to work since I get the message that this can't be performed because it can't subtract from a non-solid item. Under the Model tab, I indicated that this loft was solid (false/true) by selecting true.
You will need to make sure your loft if it has an inner and outer surface for example if your model is a pipe, that there is a surface that connects these together. This can be done via the sketch i. e if we take the pipe example the sketch for profiles would have an inner and outer circle. or you would used surfaces to close the gap between the two.
How come when you do lofts to a point it rounds out the end? Mine always go to a point even when Ruled is false. Thanks! Love your tutorials
How many profile do you have? If you have less than a certain amount of profiles then this will automatically convert to a ruled surface. I believe this is 2 but when you introduce a point then it may be more.
I had some issue creating the surface at 23:18 with version 0.20.1 of FreeCAD. There was no error message, but the surface looked like a mess. I resolved this issue by hiding all sketches before creating the surface.
I had the same issue. Your solution worked for me as well. Thank you.
Hi , Darren. I think this is a really great video for me . At this point I want to make a sheet metal skin . How would I flatten and convert to sheet metal drawing . Is this possible to do in freeCad ?? Love your videos . Have a pleasant day , Sir . Hope all is well in your world .
Terry
Hi Terry, there is a sheet metal workbench that works well but I don't know how it would deal with more organic shapes. It does a good job of making the flat shape to be cut out and bent though.
@@brucewilliams6292 Thanks bruce 👍 That will be helpful for the non organic shapes . I figure for the organic shapes I could section it and make bucks like a custom body is made and form the metal and torch weld together . Then finish from there .
@@terrylembke8100 Hi Terry, that is a good idea. Depending upon the size of the parts needed, you could 3d print the bucks. I have seen several videos on using 3d printed forms for shaping sheet metal.
Hi! I can't see this part in the playlist.
Thanks for the heads up, all fixed now 👍👍👍👍
Quick question, what's the different between fusion and compound? Thet both seems like put mutiple bodies together.
So a fusion is a complete body where all objects are fused into one. A compound they are still individual objects. That's say you created 3 sphere overlapping each other slightly. When you union they will be connected together and there will be an edge between each where they have become one object. If you compound them together there is no joining edge they are just together in a collection. The minute you click on the union button they will be joined.
@@MangoJellySolutions Awesome! Thanks
8:59 first my ability to change that y position is negative capability, second how the does one move it so smoothly. Next series a mouse visualization? maybe? please?
ok now to figure out how to make that point be editable...
Ruled surface 23:00 NOPE.
V 0.20.2
looks cool, like an open boat thing with out a transom.
So I been sponging on FC cad vids for long time but my OCD kicks in and I have total meld downs and I cant create anything I'm trying to build with curve surfaces . Simple 2d stuff for 3d printing NP . The curve surfacing stuff intimidated me :-( Saying all that to say this, so in a nut shell , you create a bunch of sketches, bring them all in to a 3d space, move them around in that space with X-Y-Z -offset - angles - rotate , blah blah . Select surfacing tools and start joining things up and ta-dah ! I know there are caveats but is that CAD ?
Yes that is CAD
@@MangoJellySolutions Thanks I needed a hug. I know now that I have to stop bouncing and focus on one cad processes at at time, like the mouse tracing episode , that process must be mastered ! few videos circulating . Cheers!
