- Discover the world of FreeCAD curves shapes workbench as we embark on a journey to create a simple boat today! In this tutorial, you'll witness the efficiency of FreeCAD in crafting not just a basic boat but also its internal structures. Learn a streamlined workflow that extends beyond boat design, and can be applied to expedite the creation of fuselage for radio-controlled air planes. Join us for a step-by-step guide, making builds quicker and easier. Dive into the power of FreeCAD with us!

I can't imagine the number of hours you have spent to refine your skills with this program. FreeCAD is growing exponentially in complexity which is a double edged sword. It's far more capable now but the learning cure is also steeper for newbies.
Freecad is a very flexible tool, though it has certain rules and boundaries it's created in such a way you can have freedom to integrate and use these tools in endless ways. You can make it as complex or as "simple" (I say that very loosely) as you like. There are a hundred and one ways of doing one thing. And this is where the boundary to master such a tool lies. Worth flexibility can come complexity.
I find if I explore multiple ways I can come up with solutions that shortcut complex tasks for a totally different subject. For me it's all about seeing modelling in a different way. That's the fun part 😊. But I don't want to keep this knowledge to myself so I share that knowledge with everyone. And I am beginning to see that there are certain basics that I need to cover and I am looking at creating something as we speak that will turbo charge the beginner experience. It's totally unique to anything out there. It's in the pipe line... And there will also be a book! 😁😁
I am going to 3D print me an RC boat from plans taken off of Pinterest. I wasn't having any luck making a hollow hull. The trick is the OFFSET. I kept trying to use the THICKEN face, and it wouldn't work. The trick is make 2 solids and then Boolean subtract one from the other. GENIUS!
I have been meaning to do this video for such a long time and so pleased it's already helped someone. :) :)
This is by far the best video on making boat hulls I have ever seen for FreeCAD.
I haven't got home to try it yet, but I can't wait! THANK YOU DARREN! Know I know why I am subscribed and donate $6 a month to your Patreon!
You must let me know how you get on! So glad I can help out, really appreciate your support as a patreon. Makes it so much easier keeping this channel going with supporters like your self :)

Awesome lesson! Thanks so much! It's a perfect compliment to your Helicopter Canopy lesson.
Great to hear, so pleased you enjoyed. 😊
This Video and the Curved Shapes Workbench opened up a whole world of possibilities
Beginners: TAKE NOTES.. I have over 5 pages of notes on this video alone...
When you cut the interior from the exterior, you used a small offset to avoid the skin being left on top. Rather than offset, which might create weird geometry (not important for this, but I can imagine projects where it would matter a lot), would it not have been preferable to extrude the top edge of the interior upwards before the cut? That is, in general you've gone to the effort of making your interior shape exactly correct, so you don't want to move it. For example, let's say you are designing a part which will be injection moulded, and it needs to have a consistent skin thickness. If you've designed inner and outer shells to leave precisely that skin thickness between them, and then offset the inner shell, the part will be thicker on the bottom than on the sides.
Made it. Great learning for me. Thank you 🙂
OMG ....... in the piont !!!!
The geometry points are always slightly off. I can't find a way to line them up, or rather, create a coincidence constraint between points on tangent sketches. But luckily the curved array workbench doesn't care about that. This trick works wonders, thank you so much for making this video!!
Well done! Thank you.
complimenti per il video una bella lezione👏
You're the best 😁
😁😁😁😁👍👍👍
Very good!
Thanks!
Thank You
You're welcome
thanks. How complicated can/must those internal calculations be of freecad... wow.
Nice tutorial! I learned several things that will improve my models. If you get a chance to cover rendering - especially if you use Linux, that would be awesome.
Please could you model a toroidal propeller for a boat like the sharrow propeller. Thanks,
:-)
Now that's an interesting request. Yes I will look into it. 😊😊😊
Hi, nice course. Is it possible to simply move the origin in FreeCAD ? Or, alternately edit keel mergin pointon origin , remove the attachement to the origin, then attach the middle of the deck to the origin ?
Select the sketch to move - then to copy and paste. I have Freecad 0.20. 2. The last dot selected prior to selecting and click copy is not selected to paste - The same dot to copy/move is selected by the program even if the selection is made by dragging up/down - left right or by clicking on a dot after selection.
Could you show which version is being used?
Very interesting. How do you continue construction to obtain a whole boat? The end in the middle is annoying; it can be avoided if the inner section is moved slightly.😁
You could change the hull curves to what shape you like. Things like cabins could be done as a seperate body and assembled together, or you could union straight on top, or pull into part design as a bar feature. Yep I have made a boat with a pretty fat back side lol
what kind of workbench is best to make watches in FREECAD ? or i do not need workbench to build a watch ?
Standard part design would be enough. Here's a good start czcams.com/video/ATKsJsxiQWE/video.html
I can draw a boat and and use the curved shapes workbench which is great but I can't make it solid! I don't know why! help?
Hi, Very interesting example but I have a question. It.s not easier to use Thickness / Shell (from other software) from Part design? I tried, after I created a clone, applied directly on the solid it's not working and I don't know why... Thank you
"i close with the line, hit close, nothing happens ..." really sad, one curve, try to close it and there it stops. when i check the offset, there is no line, freecad cant see the line that closes the curve, .. whats going on? I do exact the same. Using 0.21.1
I’m doing exactly as you following along. At 8:08 you symmetrical constraint and works. I do it and I get redundant restraints and it turns orange. Any ideas?
HUGE ! you probably can't use any of the individual arrays to do something with, there just a path ?
In a matter of fact they are a compound so you can use part workbench and explode compounds into individual objects. You can even explode the curved shape array if you just want the individual sketches.

I know its fundamental but after years I still dont get when you have to create "body" or not. Miss the old days when there was no "body"
Don't worry it does cause confusion as you can use it in other workbenches. The body from the part design is designed for a part design workflow (and sometimes used in assembly wb). The body's main purpose is to hold a origin that you can attach your elements such as sketches and Datum planes to. If you open it up in the treeview you will see the different axis and planes within which can be attached to. So it acts as a moveable anchor / 3d canvas in 3d space to hang geometry. Think of it as a frame work.
I'm concerned this method doesn't produce uniform thickness in the hull. If you're having to move an the interior object that will be subtracted 0.5 to get it to work, wouldn't the hull then have thicker regions. Is this method to try to get around our low quality shelling tool, which hardly ever works on any organic shape? Do we have a thickness check tool in FreeCAD?
I believe the move trick would work even if you set it to 0.001 so the effect would be very minimal.
i close with the line, hit close, nothing happens ...
