I've been waiting for this series for ages now! As a beginner that bought a scanner and a printer with 0 cad nor 3d modeling this is a lifeline, I'm so excited!
This are exactly the tutorials i need!! I have recently been able to get a few airplane models of mine 3d scanned. Because i want to make these models bigger and eventually make RC vehicle out of them (not the original produced model) but there is a lot of stuff that need cleaning and i may end up completely rescanning them. But this will certainly help me get the information i need out of the scans to continue with that project.
Meshlab (also platform independent, open source tool) really improved a lot from the borderline useless sluggish nightmare it was not long ago, into a quite well optimized, snappy and handy tool, might worth checking out a recent release for more involved mesh / point cloud wizardry. It has a weird workflow logic, like no undo/redo utility, instead you have to duplicate layers you might want to revert to, also weird mouse control behavior, but one can adapt to it, and it all starts to make sense after a while. Don't take me wrong, the FreeCAD Mesh workbench is a wonderful take on the subject, but if I'd be dealing with these sort of issues on a daily basis, I would definitely aim for the tool specifically targeted on this extremely complex set of problems.
Regarding the cutting off of that rear portion of the scan, to get the part to be sat on a plane. Maybe I'm confused (easy done LOL), but haven't you just lost part of the actual component by doing it the way you did? Assuming that the original nose cone was successfully (carefully therefore) removed from the aircraft and was complete, it will (presumably) have a straight rear edge where it mates to the rest of the fuselage. Assuming (again) that the part was then sat on a level surface for scanning and any extraneous data from that scan digitally removed (such as the table it was sat on), isn't that edge the true rear of the part? That being the case, isn't that rear edge the reference edge and thus the plane needs to be set against that edge (so that the component is level and vertical), rather than what seems like taking the scan and slicing off some material at the back, seemingly at some arbitrary point? As I say, I'm probably confused or missing something here, so I'd be interested to hear your thoughts.
Nice tutorials - SUBSCRIBED! I look for help with create editable surface from scooter's scan. Can U make for me tutorial? Ofcourse I will pay per your job.
Hello sir, want to ask, i've been creating some object. It's curvy. And i tried to unwrap it in mesh workbench , or make it to 2d shape in draft workbench. But it not ended with the right length as it supposed in 3D model. How am i supposed to do sir? i need it to be in 2d because i want to laser cutting the objet sir.
@fdsphone6854 Hi, thank you for checking 😃. I changed the method. Instead of using b spline, im using polyline and circle on sketcher. Then copy the surface i need on part workbench and create shape element copy. After that, create mesh from shape and unwarp mesh on mesh workbench. It seems like this is not the right way to make a file that can be used for laser cutting. But this is what I can understand and do so far. I have managed to make quite good results from this method several times. If you have another method that is simpler or easier, I would like to know. Thank you. 😃🙏🏻

Please more teaching from scan to model, from stl to model, etc
I just paid for a Kiri Engine pro subscription for the year. I'm going to maka a LOT of use of this in the coming year. Thanks!
Thank you! I never really knew that freecad is that good with meshes, definitely a lot better than my playing around with meshmixer
Definitely waiting for next one now, my otter just arrived and wanna get to work😊
Complex and fantastic! I look forward to more
special aerospace modelling. Congratulations Mango!
Thank you for the kind words :)

Very powerful WB. Impressed with it. Thanks for sharing.
Yes! More workflows for 3dscans/meshes! Car parts would be more interesting and more people could refer than to aeroplanes :P

I ran the analysis again after decimating and found non-manifolds and surface folds. It took a few more analyze/repair cycles to get a clean mesh.
Yes I have noticed each time you decimate it can cause errors in the mesh. You have to right idea, repeat the cycles until everything is fixed.
