thanks buddy. 😊

1. Open the STL File 2. Change Start to Part 3. Click Part>Create Shape From Mesh 4. Set Sewing Tolerence to 0.01 (in FreeCAD 19 it is minimum1.0) 5. Click Part>Refine Shape 6. Select Part>Convert to Solid 7. File>Export as .step file

[@freeenergyspace]

thanks for your short description

I followed al the steps in the video, but after i exported it my cnc guy mentioned that my project went from 20cm to 20mm. Anyone an idea what went wrong?

Finally an actually straight forward video on how to do this. Thank you, you are a lifesaver.

[@That_Guy5575]

I cannot thank you enough for this video. A couple of things have changed with the new update of FreeCAD, but I was able to figure it out only because of your help. You saved me from going bald lol, I was so frustrated I was nearly tearing my hair out haha

[@freeenergyspace]

You're very welcome!

[@investwiselyfolks7656]

thank you so much for the straight forward steps. kind of long but very straight to the point. Thank you for the know how. keep up the good job!

[@adrianthomas4163]

Thanks for the video. Worked like a charm.

[@GeorgeStubbs-wg6nr]

A helpful video with a few frustrating things I would like you to consider. 1. Take the time to write out on paper a script f you are going to type instructions over the video. Correct your spelling BEFORE it is typed to the screen. 2. Everyone scrubs the cursor around the screen. DON'T do that. It's very annoying. Everyone listen and stop doing that. 3. The step required to refine the shape is not very straightforward. Take a good look at the video after you are done and decide if a newbie will be able to follow. Don't assume everyone is as experienced as you are. With better instructions they will be someday. Don't give up. You are helping us learn. Thank you.

[@broderp]

I found this easy to follow. Why didn't you? I agree about the screen typing. I much prefer a clear voice over than music and waiting for the screen to show me someone typing.

[@user-vz6gu3pb7f]

Thank you so much for the Video , it is very use full and i would like to know that after converting the solid there is black lines/mesh/net type on part how can we remove after refine mesh also it is as it is , how can we change the part as we created virginal part thank for your time and looking for positive response

[@freeenergyspace]

Hi , definitely some mesh lines will be there , as we can't completely remove those as the curves are more than mesh will also be more. Try to reduce the precision it may help. But it won't completely reduce the meshes

[@sanguy123]

Thank you very much! it is very useful for me.

[@freeenergyspace]

[@joansgf7515]

Also, how much time does it get to create the shape (when FreeCAD isn't responding.)

[@freeenergyspace]

It's depend on your pc performance

[@Suzuki_Hiakura]

was honestly getting pissed off as the create shape from mesh did nothing when I clicked it through the toolbar and not the dropdown menu... not sure why the menu one worked without issue and the toolbar is bugged af... got it now and hopefully PCBWay gives a decent quote under a hundred dollars lol

[@sanginchoi3293]

The tolerance lower limit can be changed. Edit --> Preferences --> General --> Unit Tab --> Number of decimals 2 - change to 3 --> 0.001

[@freeenergyspace]

But it takes more cpu power that's why we used less

[@broderp]

You didn't show the final STEP file. Does this process remove all the facets on the model?

[@freeenergyspace]

No , It won't remove completely as the curves are too high facets also will be high

[@user-lx9jm1wo3h]

How do you remove the mesh once it is step? I am looking for a prismatic step like how fusion does. Is this possible with FreeCad?

[@broderp]

My question exactly. The final STEP file was not opened after it was exported, so I can't tell if the mesh has been removed or not. I also use Fusion360 and the free version can be a nightmare to remove the mesh to make a file clean for proper editing, unless you pony up for a $500 a year subscription!

[@user-lx9jm1wo3h]

@@broderp Yea Fusion 360 is a ripoff for small hobbyist. The price should be a one time payment for stand alone version rather than a subscription every month.

[@alimozaffar6884]

thanks

[@shingrutashish5639]

In mine it's not converting to solid

[@racketman2u]

The bad news is that this process isn't foolproof, sometimes the mesh gives a "shape is not a shell" error and won't convert to a solid; also version 0.18 seems to work more often than version 0.19 and 0.20 for some reason.

[@suprayz5321]

[@freeenergyspace]

Some models can't be converted back to solid because of its complexity

Very helpful video. when I export as a step file, do you know how I can reduce it in size so that I can send it by email?

If meshes are reduced, file size also reduces , otherwise compress it in zip or rar file

If your model is too complex with more surface it's unable to compute it properly check the error in stl files before starting the process

If the model is too complex( lot of curves) then you have to reduce the precision to work
