stock-varify

[Rakesh]

Hi everybody,

I have customer send casting model and when I use it for a stock as stl file it give the message as "Lw has found the STL file not to be closed and watertight. An approximation will be used as stock". This give the approximate model for stock. I analyse the model as one solid.

Any body have any idea how I can get the exact stock instead of approximate stock model.

Any help will be highly appreciated.

thanks

IMO don't use and stl. import it into the file on a different level and a solid and use the solid to verify

John, I try your way it again give the approximate stock. Now I put he dwg on ftp as MCX2_filesrak_99.zip

If anybody can help,thanks

sometime it works to play tolerance.

Rakesh, I have fixed your stl file.

Even solids do not work very often.

 

3D Solutions_stl.zip in the MCX2_files dir.

Bruce,

Your stl file is good, Thanks for your help.

Can you share what you did to make it working?

Rakesh,

 

We purchased a piece of software called Magics RP that will let you edit and fix problems with STL files. It costs about $10k a seat, but it sure is worth it. We had some files here that were around 50 MB and we reduced them to about 1.5 MB. It really depends on the actual tolerance that you need to hold your model too.

 

HTH,

Rakesh, Like Colin has indicated, I have some

software that I use to fix the file.

Thanks Colin and Bruce for the information

Bruce,

 

Are you using Magics for your STL healing or something else? I'm always looking for new software solutions.

 

Thanks,

I often have this problems with V9.1.

 

Tips to avoid watertight issue:

 

- Make STL file from a solid (it must be isolated on a level)

- Play with STL tolerance

- Use STLheal Chook

- Import/draw with solidworks then save into STL with SW (which is much more reliable with STL).

- Create toolpaths, verify with a standard stock (or a fine STL rough file) then save STL from truesolid verify (not that easy sometimes...)
