dwg problem

[PeterM]

I just got some dwg files that I am unable to open in Mastercam. I can see the thumbnail in the preview window but I get nothing when I convert. I also tried it in m9 to no avail. I have placed the three zip files onto the FTP site in the files to be converted to mc folder. I was wondering if anyone out there can answer why I cannot open those files(unzipped). I've allways loved the range and power of mcams standard converters and this is the first time that I've had a problem. Thanks

Got names for these files? I'll give it a try quick.

Could the entities be Blanked?

[Pete Rimkus from CNC Software Inc.]

Most likely there are only paper space entities in the file and (by default) we're importing them as blanked.

You can either ...

1) read in the file and then go to Screen/Unblank and select everything; or,

2) before reading in the file, go to Settings/Config/Converters and uncheck "blank paper space entities in DWG/DXF files"

3) after selecting the file but before clicking 'ok' or hitting 'enter', use the 'Options' dialog and uncheck "blank paper space entities"

 

 

Most AutoCAD files contain Model and Paper space entities - we use blanking to help you keep them separate.

Is this one of the files 7791341-bscrev.igs

 

if so it opened fine for me.

 

I could save them as an .mcx if you wish

I couldn't even get them to open in autocad. It said not a valid file.

[PeterM]

3 zipped files, rough turn front, rough turn back, finish turn datums, I already looked for blanked geo, I didn't find any.

I was able to open them in AutoDesks TrueView. It looks like diferent Paper space layouts. I didn't see anything in model space & when I tried bringing them into X2, I couldn't find any geometry (blanked or unblanked).

[John13]

I got what 3rd String got in Solidworks and tried importing into Keycreator and got conversion failed message.

[Pete Rimkus from CNC Software Inc.]

If there are only named layouts in the file and no "model space" or "paper space" entities in the file, then you probably will get nothing. We have not yet worked out a mechanism for handling multiple named layouts (but we're working on them). We may end up dumping them to separate MCX files.

I'll take a look at the files and see if there's any other help I can give.

Here's more...

 

The model space section of the DWG file(s) contain 'external reference' entities. These are additional DWG files that are called into place. Perhaps the part data is in that DWG file?

 

For instance, RoughTurnBack.DWG refers to a DWG file found in J:CAPSTONE518110MOS...and so on...

Pete:

 

It sounds like these are MCAD Assemblies. Is this what would be expected when you tried to import a dwg assembly?

[PeterM]

Thanks for all the input. I'll have a chat with the people who sent me those files. I'll give you an update when I know more.

Could be, though I don't know much about them and I do know that MCAD can save multiple 3D Solids in as single file.

I also know that we cannot import the data from external references. And in this case, we don't have access to the referenced file so it's hard to say what to expect.
