STL compare

[Fred from Université de Sherbrooke]

Good morning!

I got this problem while trying to write a STL file with the converter..."Not enough memory". Is it a limitation from Mastercam or do I have to do some cleaning somewhere.It's a uge file.

Thank's

STL Files can get HUGE depending on the tolerance you're saving to, how big/detailed the part is.

How much RAM do you have?

[Fred from Université de Sherbrooke]

My file have 27200 KB.

I've put the tolerance to .1 and it still does'nt work.

Thank's

Fred what is the allocations in the config for ram in the computer.

And how much RAM do you have?

This seems to causeing you a problem.

I am also having a problem creating a STL file for use in verify. When I try converting using a .05 tolerace I get not enough memory. I have 256 meg of ram and my MasterCam allocations are set to use 207 meg. The surface file I'm trying to convert is 952K. I searched and found this thread but I don't see an answer. Thanks.

mmonica,

you are saying when you try to make a STL file that has a large tolerance of .05 with that much ram it wont do it?

Do you still have this file?

If so i would like you to put it on the FTP so i may try it.

then from there i will see if it does or does not work for why for you.

I have never had a problem makeing an STL in the past but lets start with the file and move from there.

thank for your time.

Jay,

I'll post the file. Thanks for your quick response on a Sunday. On a side note, I tried it in ver 7.2b and it created the stl file using a .001 tol, the file still looks corrupt in verify in ver 8 (1.26.2001), this is not a big issue, but I like to verify using the model to make sure I don't hit any interior walls when milling.

Thanks Again

Hi marc are you able to get this?

Pic of STL

this is with a .001 tol.

Oh and yes i am getting the not enough memory on top of it.

[mmonica]

Yes, that is what I get, when you go to verify thru the op manager, select file under stock, the file looks corrupt.

[cadcam]

Ok i will try this in a while have to step out with the family for a bit.

Hi Monica,

I think it's a parasolid file that was converted by MC. I had a problem like that before.

Please check all the surfaces of your model to verify that it was converted correct.

It's a good practice to convert your model from vda to MC. And in my opinion, trimmed srfs are better manipulated in MC.

What are saying about the Parasoild?

I am not following this thought.

thanks

[kwolf]

Indeed I really exprienced such a problem with solidworks files. Even some surfaces were lost. I export the model from SW to VDA and import it to MC.

SW 2001 Sp 7 or 9

MC 8.11

Thanks,

Ok i see now.

Well this is what i did for marc.

under a folder called Solids on the FTP you will find your file in Zip state.

Inside your file is now a solid and all so a new STL from this file.

This should work.

[kwolf]

Hi cadcam,

Is the STL file from MC or other CAD Systems?

[cadcam]

both the stl and the solid are from mastercam.

[kwolf]

Sounds good.

How did you convert those srfs in MC to Solid?

By the way is it ver13(Parasolid)? I imported the X_T into SW 2001 sp11 and it detected 5 srfs and was not able to knit them together.

Thanks,

KWOLF

[kwolf]

Ok at least I found that there are 5 solids in MC which is not possible for SW to have them in part mode.

but how about converting srfs ...

[cadcam]

Well i would like to tell you .

But at this time i can not descuss it on this forum.

But i did do it in mastercam.

[kwolf]

I found that there is 1 srf on which those 4 first solids lies, it means a solid with zero thickness?

[kwolf]

Ok

But will you please explain it to me by e-mail?

thanks,

KWOLF

[cadcam]

Kwolf,

You can go back to the FTP and get the *.prt file of this part.

From SW2001.

[kwolf]

Thanks Jay,

I got the file.But it is still srf not solid.

Thanks again,

Kevin

Jay and Kwolf,

I can create a good stl file in both ProE 2000i and Solid Edge V10. I made a parasolid from Solid Edge and when I try to convert in into MasterCam I get a error in GETMOD:

Parasolid Kernel Interface Error

PK error code: 970-

open/close/read/write error for schema file - check PSLDDATA directory

This is not a big deal, my program is written, but I just got to like the verify feature. I'm just curious as to what I'm doing wrong, or could this be a bug.

Thanks for you help
