Opening Solidworks Assembly files

[MBlair]

Hi all, I have a problem opening .SLDASM files. I get a "Cannot find Parasolid data in Solidworks file" error. I can open Solidworks .prt files just fine. I'm running X4 MU3 on a XP Pro system.

[Dave.L]

Do you have all the .SLDPRT files associated with the assembly?

 

What release of SW?

 

I just tried it and an assembly opened for me fine.

[bhyde]

What size is the assembly file? (bytes, kilobytes, etc)

[MBlair]

Yes, all the .SLDPRT files are there.

We're using Solidworks 2008 service pack 4.

And the file size is 1,895 KB.

[Dave.L]

Maybe try and save as a parasolid and open that way. If you want, email them to me and I will try it.

[MBlair]

I can have the engineers save them as a .SDPRT file but I hate having to go through another step.

I also notice that I can see the .SLDASM in the preview window of the "file open" dialog.

Thanks Dave, I'll send you a sample file.

If the parts were not "rebuilt" before saving and exiting SW you may get that error. I think this has come up before, you want to try and search for it if by chance you haven't.

My MC reseller is looking into it. I sent him the files and he can open them in MC on a system that has Solidworks but can't open them on a system without Solidworks. Unfortunatly I don't have SW on my system.

[Brad St.]

Interesting, please post what you find out if you can.

 

Good Luck.

Update, my reseller contacted CNC Software and this was their reply: "This is an issue with both 32 nd 64bit machines. It has been logged as that defect number and is being looked at."

I have not heard anything since.

put the free solidworks (edrawings )viewer on your box see if that helps....

[gcode]

have your engineers save the assembly as X_B

Mastercam will open the file with no issues at all

Using X_B you can also define your WCS and control the file's landing in Mastercam.. Its well worth the extra step

[MBlair]

I do have the edrawings viewer on my machine. I can get the engineers to save it as a part (.sldprt) file and open it, I just hate going through another step if we don't have to.

I tend to have the same problem. Every single time I try to open a solidworks file (part or assembly) in MCam, I get the same "no parasolid data" error. It bothers me a little bit, but I just save my SW files I need to use in MCam as a parasolid to bring them into MCam.

 

If you find a real solution, I'd be very appreciative.

One thing that can cause this is a conflict between the two versions of SolidWorks' SWDocumentMgr.DLL that get installed 1) when SW gets installed; and 2) when MC gets installed.

 

We put a copy of that DLL into our CommonSWorksData sub-folder. SW puts a copy into "Program FilesCommon FilesSolidWorks Shared".

 

You can try shutting down both SW and MC and then re-registering simply by opening a DOS prompt, browsing to either one of those folders, and running "Regsvr32 SWDocumentMgr.DLL". If that doesn't help, do the same but this time browse to the other folder and try again.

[MBlair]

I only have the MC version of that file because I don't have Solidworks on my system.

[Pete Rimkus from CNC Software Inc.]

Thanks.

The same sort of thing could potentially happen if you've got multiple versions of MC installed. You could try registering MCX4MU3's version of that DLL and see if helps.

[MBlair]

I do have multiple verersions of MC installed. I registered the DLL as per your instuctions, it registered successfully but it still doesn't work. I keep getting the "Cannot find Parasolid data in Solidworks file".

[Pete Rimkus from CNC Software Inc.]

I was hoping that would do it. The reason QC was so vague with their response is that we really haven't narrowed down why something that works on most computers doesn't work on a few.

 

Question time:

You're running X4 MU3, right?

And it's 32-bit Windows XP?

And you can read SW Parts just fine?

And it happens with every SW Assembly you try?

[MBlair]

Yes to all questions.

[SCOTT.R]

I have the same problem. I am also running X4 MU3

with windows XP.

[Marshal]

And my problem comes while running X4 MU3 on 64-bit windows, but I can't open SW parts or assemblies.

 

I wonder if there's a setting in SW to save the parasolid data in the part and assembly files?
