It's the exporting to a step file that fixes the error. You can just import the step file right back in to FreeCAD, add it to a new body, then apply the fillet to it and it will work just as it did in LS Prepost. The problem arises due to mirroring the pipe and the edges you get in the middle are a pseudo edge of two overlapping solids as far as FreeCAD sees it. Exporting to the step simplifies the object removing the extraneous sections and defining the edges clearly. EDIT: So I was able to make it work without any exports by eliminating the use of mirroring and creating 2 paths, one for each pipe and the fillet applied as you would expect.
Have been stuck trying to get it to snap to the dots for 30 minutes. This comment was a life saver! Snap endpoints must be checked and it worked straight away! Many thanks.
FreeCAD is very powerful but not intuitive, I'd never thought about the Draft module to make that part, the wireframe view for pipe sweep is also very useful. Thanks.
DuyQuang Dang's channel just released a video on manual and default fillets. You can use them as chamfers if you leave the curve at zero. The video before is on manual fillets. If you look at about 16:36, you can see the changes in the wireframe that were made. Thanks for the video.
You can sketch the outer diameter (here 15mm) and inner diameter (here 11mm) as two circles in one sketch. If you STRG-Select both circles and use an additive pipe, you get the final (already hollow) pipe. That way you also would not have to alter the wire. Is there a specific reason why you chose to use the additive pipe first, then alter the wire to add the point below and then use a subtractive pipe. It seems a bit laborious. Anyhow. Thank you for the great Tutorial!
How would we proceed if pipe radiuses were not equal? Since they are 20 with this sample (05:08), giving a single 20 fillet radius to polyline does it. How about two different one?
I tried filleting in between the pipes in FreeCAD v1.0.0 and it works through 1 to 31 milimeters but only stops working on 6mm and 28mm. I also tried the same with the same project with a weekly build and the behaviour was the same. Overall, it works when it works, it does not when it does not. 🤷🏻♂ OS: Windows 11 build 22631 Architecture: x86_64 Version: 1.0.0.39109 (Git) Conda Build type: Release Branch: (HEAD detached at 1.0.0) Hash: 2fcc5317fe3aee96ca73475986a577719fc78e20 Python 3.11.10, Qt 5.15.15, Coin 4.0.3, Vtk 9.3.0, OCC 7.8.1
It seams that I'm doing something wrong. The line is not snapping in 3-dimensional and is finally flatt and if I turn the object 3-dimensionally is not going through the points. (I am using 1.0.0 Rev 39109, Win 11 build 26100)
Does Part Design have an ability to "refine" the shape the way you can in the Part workbench? That would allow that one fillet you were unable to do. I mostly use Part, though.
I have not been able to get past drawing the line in the Draft workbench. I can not get my polyline to attach to the first point placed on the top surface. I am brand new to this and am watching many videos to help me progress. I was doing well on this until this point. Any helpful suggestions on how to snap the end of the polyline to the point on the top surface and each point thereafter?
@@RandyShort-u6t Hello, once you are in Draft workbench try clicking on "Snap perpendicular" (which has a symbol of upside down T), or "Snap center" (Symbol of a target), or "Snap intersection" (symbol of X). Let me know if that works.
@@ComputerizedEngineering That did not work. The line is snapping to the bottom grid instead of the spot on the top. Tried all the snap options but still going to the bottom.
@@ComputerizedEngineering The last end point of the polyline appears to be snapped to the grid. I can not get it to snap to the point that we placed on the datum plane. And I have not been able to find where to possibly turn off snap to grid. I appreciate any help.
If the polyline is snapping to the bottom grid then it is possible that you have activated "Snap grid". Try to replicate the snaps that I have activated at @5:04 and leave the others deactivated. I hope it works out for you. If not, let me know again.
Hi, I encountered exact same problem! After some comparison I realized my draft buttons were not toggled as in the video. I thought the reason could be I was using "Ribbon Interface". Disabling this add-on solved my problem. Now I can toggle buttons like in the video and draft points snap on my sketcher points.
Did you use Check geometry with BOP check enabled to determine if the solid is in fact valid? It is very common for the this sort of merged pipes to produce self intersection and other geometry errors.
not exactly a question about the video itself but where do you find the setting to hide the lines you are trimming? Mine just turn a light green. All the videos i watch it seems everyone else has found this option. For the life of me i cannot find it. I can't find it in the freecad forums or doing a search on the internet. I get way too many irrelevant returns. thanks
When using the polyline tool, an option box used to appear to input measurements and angles as shown in your video. Now it no longer shows up. Any advice on how to reactivate it?
The problem with the freehand b-spline is that it’s really hard to use precisely. It actually has number parameters, but they’re very difficult to use. Probably why it’s called ‘freehand’.

@ComputerizedEngineering: This comment should be pinned!
could you also leave the mirroring step and then recalculate the mesh?
Amazing video. I'm glad you shared it.
Showing what and how will be done before style is excellent. Thank you
thank you for this tutorial, it is very useful for me as a beginner. greetings from Indonesia
Excellent tutorial
Make sure the snap endpoint green icon is ON in the Drafts workbench. Otherwise it seems like it snaps but it won't.

This is so good! Very good tutorial, well explained and very interesting model. Thank you!
Great job, nice tutorial
Very informative. Thanks for the tutorial.
Very nice example! And great program lsprepost, didn't know about it.
Thanks for sharing , looking forward for more videos of your teaching .
Great tutorial, thanks

You're absolutely right! FreeCAD is incredibly powerful, but it does have a steep learning curve.
Thanks, This’s a great example !
great one !

Very usefull, great job.

You may be able to create that fillet in FreeCad manually using Surface or Curves workbench.
Very great. Thank you 🙂

ottimo tutorial grazie. se posso fare una domanda lo svuotamento del tubo si poteva fare anche con lo strumento thickness ? grazie.
thank you
nice tutorial... couldnt you just shell the pipe?

I'll be making more videos on 3D sketching to cover various scenarios like this.

All was going well until the missing feature required using alternative software not available on all operating systems, unlike FreeCAD.
You can export as a step file and import that back in to FreeCAD and apply the fillet to it after adding it to a new body. No other program required.
@@TheREALDocRabbit or just do a manual champher, and still keep your timeline stuff

Lol, too fast to me also but we can pause the video at anytime Bro
Hi, what about to create 3D curve by combining 2 planar curves instead using the datum plane? Thanks.
