This is a Rhino 7 Tutorial about converting STL mesh model to CAD (NURBS format). This type of process is of relevance to Reverse Engineering works. It may be useful for the conversion of 3D scanned data into usable NURBS-based surface model.
Commands covered include the following:
Quadremesh
ToSubD
ToNURBS

Your videos have saved me so many times i've lost count. So helpful and informative. I can never thank you enough.
You are so welcome!
Thank you for this tutorial. It helped me solve a problem for making an electrode from an stl file that needed to be nurbs to make a curve from an intersection so I could extrude a straight part. So helpful!
Wow.. sounds interesting. Glad it was useful 😁
Rhino 7 is great value for the buck. This is going to make reverse engineering more affordable.
Great video buddy! The only one to explain this, in fact.
Thanks. Glad you think so!
This is very helpful thanks for the guide! I look forward to upgrading to version 7 soon
Glad it was helpful! With Rhino 7, the ability to speed up the reverse engineering process is a huge advantage for me. I used to do much reverse engineering work and it was tedious with the older versions of Rhino.
To me, this tool alone (Quadremesh) is worth the upgrade as similar reverse engineering tools are very expensive.
Can may wish to subscribe to this channel as I will be putting out tutorials related to Sub-D
Just started with Rhino, and this WAS FIRST helpful video in NURBS objects!
Thank you :)
this is the best tuto ever seen thanks a lot
Thank you
Excellent and to the point. Thank you.
Thanks :)
my friend you've SAVED me. Thank you so much...... If you come to Greece let me know and I'll buy you a beer or 2
LOL... thanks for the offer. Really appreciate it.
Have a nice day :)
Thank's man! You helped me a lot.
Most welcome
Great video as allways !! Thank you!
Thanks for watching! Have a nice day 😁
@@simpernchong How can I contact you?
Very useful video. Thank you.
So nice of you
thank you - it was useful!
Glad it was helpful! Thanks 😁
Thank you always!!
Thank you too!
brilliant. thank you for this
Glad it was helpful to you. Thanks. 😁
Thank you so much
learned more from Asian Man on TH-cam than I have from anywhere else.
Thank you Sir for the compliment 😆
That’s objectively racist, would you call a channel “Black Men”
u saved my life thx alot!!!!
Thanks. Have a nice day :)
Great man
Glad you like it. Have a nice day :)
i hope you do more reverse engineering tutorials
amazing feature
I think so too..
You are Legend 💪😍
Thank you. Have a nice day :)
Good , thanx!
Thanks Anton :)
Thanks.
You're welcome
there is lot of good tips there
Thanks and have a nice day 😄
How can we convert an mesh solid to an solid in order to save it as step cause now i only can save the geometry that i create as an stl file while i need it as step plz help me
Hi, thanks a lot for the video. How can it be used for reverse engineering of 3d scan data. Could you please elaborate? I work with point clouds and getting into modeling lately.. Thanks in advance
Hi, ehmmm... i think point cloud will be more tricky. I know in Grasshopper point cloud can be converted to mesh using the Delauney component. Perhap, need to use Grasshopper for process the point cloud to mesh and then process to use the process as illustrated in this video. Cheers.
your mesh seems to be converted from a cad file so this is the reason the functions works fine; I would use a real scan data exported from a scanner software and retry.
I have did that before (using real scanned data).. it works. However, I will have to fill up holes first using a mesh tool such as Mesh mixer. The reason for not using a scanned data is because I do not have one that I am allowed to use.. all the scanned datas that I have are from clients for their reverse engineering project...hence bounded by legal agreements. And I do not have a 3D scanner. Because of this, I have to resort to using 3D mesh model that is created by myself for this video demo. Cheers.
yes, I know that many scan files are confidental; but I wanted to see the performance of this tool on real scans which have irregular surfaces; It seems to be a very useful tool and looks much better than many other auto surface tools; thank you for the introduction; I am planning to install the trial version of Rhino and give a try myself :)
@@ataarturk2411 Bro, this is the tool i was using to fix the scanned data. meshmixer.com/download.html To be honest, I don't think it is possible to take freshly scanned data and convert them into NURBS. This free tool is quite useful for smoothing and autofilling of holes. cheers.
that disclaimer makes me feel like i'm gonna be put on trial if i try these commands. yikes!
however... the video was quite worth it. so maybe #worthit
Haha... Of course not. 😆Just to protect myself.
I need help to convert my blender file to step as an editable file in solidworks.
Hey dude could you make videos about reverse engineering
Most probably. Thanks.
Hi, what version of Rhino does the SubdTool get introduced.
Version 7.
@@simpernchong can you help me with a blender file, to transfer its format to step, so i can edit it in SW
This is Not Reverse Engineering of Scanned Data
It is merely translation of an stl file to cad (the file is previously converted from CAD or other type to STL mesh).
It is important to note that scanning will not produce perfect mesh or polygonal model, even with the greatest technological advancements; so the scan needs repair.
This whole process may be applicable to items with large tolerance of 0.125" and more.
Accuracy of the produced cad file is utmost important in many industries. This software and the operator do not show capability to accuracy.
Don't kid your self, there is no 5 minutes reverse engineering as well as scanning. It takes time to preproduce the scanned object to a useable cad file with decent accuracy.
Other software packages depend on engineering work such as sketching and solid modeling from the scanned data. So far I have not found or seen a comparative way in this software to do reverse engineering. It may be good for other tasks but not what the title of this video says.
Get a real scanned data with holes and other imperfections, repair it, prep it, and than show me the same steps as you did in the video.
Cheers to all,
DR
Noted on your sharing. Thx
Can you do a video on adding gems on stl
Sorry... rhino does not excel in stl or mesh works.
@@simpernchong can you turn into nurbs and then add/remove gems then turn back to stl. I honestly don’t know but I think it’s possible. If not then ok.
Hi, can you edit my STL file to stp file? For money, of course
this is working for rhino5?
No
@@simpernchong thanks for clarification and for the great video! Good job.. i watch your video and really enjoy...question, any videos of formatting i mean to import stl to rhino 3dm to rhino i thinks solid is stl format right? and i have parts plastic want to know how to squeez the plasric through all my parts but as i kow solidworks plastic fit on it but whole solid works cant download with many reasons ..any programm which i can do it with rhino 3dm format? because i would like to know how the polimer melts going through whole my parts as simulation during injecting... shortly i did my 3D parts but am not sure where and how to build hole and lines which is melt polimer goes proper ways and filling my prts in the metal mold.....
@@talgtalga3767 Hi, so sorry. I do not know of any injection mold simulation software. Cheers.
@@simpernchong strange so many it companies and technolgies the world doing business with plastic more than 10 years and no simple programm ...except Solidworks:-(
@@talgtalga3767 😁😁 I see...
Hello Brother thank you for your useful video.,
Do you also give privat lessons. If yes
Could you please give me your email so I can contact you.
I live in Germany and I want to use rhino in Orthopaedic.
Thank you
