Curves WB is almost impossible to learn without a video series such as this one. Thanks for your service to the community; these videos have taken my skills to the next level. I can't imagine how many hours you spend on researching, making videos and getting them ready for publishing , but I hope many will benefit from this in years to come.
Thank you for such a kind comment. I do spend many hours figuring this out but it gives me great enjoyment sharing this knowledge and making people aware of what FreeCAD can do. Thank you once again and I'm pleased your enjoying the videos.
Thank you for this series on curves. This is a timely series as I am about to embark on modeling a 1925 fireboat in FreeCAD. I built this fireboat from scratch based on the actual ship's drawings about three years ago and then donated the model to the Los Angeles Firefighters Museum in memory of my father. My father was a fireman for the City of Los Angeles and was assigned to this boat for WWII. The model construction was traditional frame on bulkhead using wood and polystyrene products for the components. I was introduced into the world of 3D modeling for a few parts I needed in this project. I found and fell in love with FreeCAD . I love CAD anyway as my post high school training was as a draftsman - first pen and ink with drafting arms/machines then onto computers and various flavors of AutoCAD. Now that the boat is done and gone and with spare time I wanted to model the boat in FreeCAD so this is great and helps explain a lot (I may post a few 'how would I' questions as I dive into the project). Thank you again and I look forward to more of your videos. Larry
Thank you so much for sharing your story. It's great to see your keeping the memory of your father and the great service he bought to the world alive to this day, he would be proud. I am totally unaware of how far back fire boats go in history and I will be doing some research later. It brings a smile to my face that you have chosen my tutorials to help you with your journey once again. Thank you
Thanks for this, this workflow seems ideal for designing a skateboard mold, either the mold directly or by designing a board first and "cutting" a mold from the board design. I'm going to have to try this out.
Thanks for the comments regarding what you are going to try to use this for, always good to get comments like this as it gives examples of use. Glad you enjoyed the video.
This vid is so useful, as I'm just diving into FreeCAD for hull design. I will say that - generally for boat design, and more specifically for me (multihull design) - simplicity for surface integrity is a priority. I'm curious to see how far FreeCAD can go in creating manipulative hull surfaces so that displacement and other feature numbers can be changed while minimizing resetting continuity. Certainly looks like FreeCAD had a lot of constraints that can be applied!
Hi Darren, Really enjoying Series, have been able to design own 3D RC Aircraft. As usual FreeCAD can be a boit Idiosybcratic but (especially when doing sufaces and the like). I've found saving often (older PC) helps performance.
Great to hear your progressing. I find open source in general can be a bit like that. I use shotcut for video editing and it constantly runs out of memory. I am the same, laptop that is 15 years old but still going strong. If it works finally on mine they it has to work on something a bit more powerful (that's my excuse as computers have got very expensive of late!)
Great video. Now I'm verry interested in the next step of hull design. Creating the bulkheads and interior walls etc. to match and follow the curve of the ship. And of course give it a thickness, I would love to be able to model a ship in real size and then 3D print the scaled down parts for model building
Thank you for your comments, glad you like. I have a video regarding flattening lofts where I create a very simple boat and section up the surfaces. It's more for technical drawing and creating the shapes for extrusions for cutting on CNC. It is a step towards what you are looking for but I have yet to do a full video of the whole process and get detail into the bulk heads.
Great video, thanks for sharing. It´s great complement to the Hull & shovel designs of your past videos (4 months ago?). I have the same sugestions / questions of "fullsendmarinedarwin" and "hidingin": I discovered Freecad by trying to do reverse engineering in plywood canoes. I think this is the first video I see that shows how to make surfaces with reference dimensions. Now, I miss the how to on "flatenning" or getting plank dimensions. Hope you may work on that and teach us how to do it. Again, great video.
Thanks for the comments great to hear you are liking these videos. This is the first venture I have had looking at boat making and it is fascinating area. Believe it or not I am sitting here with a techdraw print out on paper, tape and scissors piecing together what I think is the solution with better results than I expected (bit tricky with just paper as the recycling as been so didn't have any card) . I am going to make a video on what I have done and release early this week on my channel I knew the tools I needed in CAD as I used to make parafoil kits for a hobby and have used a similar concept. I just had to figure out a similar workflow in freecad. And I think I got it or near to it. Have to say its been the most enjoyable research and journey I have had to date.
Just to let you know I have now released a video based on the questions regarding flattening the loft. It's been fun working in this area and I would love to venture further. Hope the video answers your questions.
Great video, and for me it was very good timing. I have four attempts to make a Falcon 9 Landing Gear fairing sitting next to my 3D printer. I was only using the tools available in the Part Design workbench. I'm going to give this a try. I have also never used groups before. They make sense in the context you used them.
Great to hear you found it useful, nice to hear how people are using my video's as well, always interest what projects people are getting their teeth into.
Grouping the frame dimensions with interpolated curve as first section,using this group format for the other section's format,after changing the dimensions on each section gives the skin of curve's network surface finally.
What I can not believe is that I can't find the most simplest answer to a question I'm starting to wonder if FreeCAD can even do. I have a custom flat object which I simply want to curve along a path. I have come close to what I want but most run into the limitations of FreeCAD and I find that I'm starting all over again. Can it be done? Make sketch, pad sketch, create custom path and then click button to follow the path to create a new object? BTW, GREAT videos.
Thanks for your comments glad you like the video. Sounds like you are looking for sweep along path or edge. You can sweep your sketch profile along a b spline or edge of another object. Available in both part and part design workbenches.
@@MangoJellySolutions I simply want to bend an already padded object along a path so I then can use it in a pattern feature. Most all ways I have found to do this uses the face of an object and or can not be in both ways duplication using the pattern feature. I can't wait for 0.20 :)
Now to really throw a spanner in the works, for physically building from a CAD model, would there be anyway of flattening the surface so you could create cutsheets? Building it this way in FreeCAD allows you to build bulkheads which is awesome, but It would be nice to be able to approximate the surface as a flattened object. I understand there are certain constraints when flattening a complex 3D curved surface, sometimes the material IRL would pinch but if you keep the panels within constraints is such a thing possible?
I know exactly what you want. I used to do a lot of foil repair and kite making (open and closed foil kits same construction as a paraglider) and the software I used I was able to flatten the kite in to its 3d form to make cutting templates to transfer to material (ripstop) . There is ways in the draft workbench to flatten objects into a 2D view but I have never had a reason to use it. Also there is the sheet metal workbench which I have used to make a couple of cardboard models and I am wondering if the curves wb can may together with it. It's an interesting question and one I think will be pretty beneficial for researching. From curves to print / cut is on my long list of videos to tackle.
Getting close to an answer .... I think, combination of two other workbenches. Need to do some tests to see how successful it is by converting the results to a sketch and measuring. May have to print out and transfer to cardboard to see if it works
Just to let you know I have figured this out and am putting together a video on the technique. Even tested with output to paper and created a paper model of the CAD model and all fits together fine. Will be releasing on Wednesday, just got to edit the video.
I have a question for you ? I want to make a flowing curved part using the curves workbench you have taught . picture then cutting this into sections like ribs on a boat hull . then I want to take each slice and use to convert to g code and use my router table which is CNC and machine these to make ribs for a buck so i can form sheet metal to it , to make a body how would I do this ?? can you help me please
Sorry for the late reply. I thought this was a very similar question has been asked by another viewer but on further reading theirs is different as they are trying to flattern the shape so they can bend it into position. To make cross sections there is a tool In the part workbench called section, I often use it to create section views for technical drawings. Its icon looks like a series of red slices through a cube. You can use this to make faces of each of the cross sections which you can then extrude. I'm in the process of putting together a quick video on this tool and it's made me rethink what this tool can be used for. I think it can be a great shortcut for what you want.
Just to let you know I have figure it out and tested it by making a small boat in paper from the ribs and profiles and all fits together fine. Now putting a video together to release. It should be out on Wednesday
This is very different from Blender 2.93 you can create some excellent boat models in Blender but will have problems exporting them ready for CAD if you do not know what you are doing.
@@MangoJellySolutions have you actually applied a 3D offset to these surfaces and created a valid non intersecting solid? i know the tool exists, but it is famously temperamental.
@@edwardvmills Yes I have and yes I have had problems but there are solutions, I did a video about ways of resolving these about a month ago. With the curves workbench certain curves that you use to make up lofts and gordon surfaces can be switch to custom mode. These then expose the continuity settings. Switching these on I found that I was able to get the offset to take by changing it to a different C(n). Running them through the geometry check on the part workbench showed no errors.

This is incredibly powerful! Way better than Fusion 360.

Thankyou for fulfilling the request!! epic!!
This is fantastic and exactly what I was looking for! Thank you!
Glad it was helpful!
This is so good! My limitation in FreeCad has been with curved surfaces. Which has caused me some announces. But this clears a lot of thing up.
Thanks for the comments and including what you was finding a challenge with Freecad , glad the videos are helping.
Thank you for your high quality videos.

Can you draw a pirate ship galleon in freecad? Nice Tutorial! 👍😊
Thanks for the comment glad you liked the video. I think with this method and time you could.

Sir how does rotation sweep works in curves work bench ?
Is it possible to add a thickness to the complete hull so it can be 3D printed?
Yes, if you use the 3D offset in the part workbench that will allow you to create a solid hull.

When I set to periodic I don't get a loop and when I set polygonal it doesn't follow the polyline. Any ideas anyone?
