Autodesk Converter

I don't know if this is actually a bug or if I'm doing something wrong, but when I import some AutoCAD LT 2000 (yuk, by the way; LT bites) files into MC V9 Lathe I seem to have strange occurrences of added entities.

 

For instance, I just brought a drawing in (that I drew myself) and when I did a screen fit zoom I saw entities way off of my working area that ARE NOT THERE in the ACAD file.

 

I'll try that again... If I zoom extents in ACAD I only see my part and chuck jaws, when I screen fit in MC there are entities shown way off to the left; has anyone else seen this?

 

I also have had a case where there were 2 copies of every entity on the part in MC but in ACAD there was only one.

 

Has this been seen by anyone else?

 

Thanks

Assuming (always a bad thing ) that AutoCad LT is fairly close to full-up AutoCad.... If you have entries in the paper space as well as in the model space - both spaces are imported into MC and show up as duplicate geometry. Often the paper space import will show up to the left and above the "real" geometry. One "work-around" has been to delete the paper space prior to bringing the AutoCad file into MC. This is inspite of the "Blank Paper Space Entities" button in the DWG/DXF Read Parameters popup (usually this works just fine - but occasionally it doesn't).

Somthing else to look at Chris - do you have any blocks in the Autocad drawing? Un-exploded Autocad blocks do not translate well into Mastercam.

If you would like to email me the Autocad file I wouldn't mind taking a look at it!

You might just make it a DXF they seem to convert well.

Kathy,

Unexploded blocks should come in with a pretty good success rate in V9. I'll admit that it wasn't so hot in V8, but we put a lot of effort into improving it in V9.

You can send files that don't come in cleanly to [email protected] and cc: me at [email protected]

Thanks for the insight folks; I'll check those options out. If I keep running into it I'll email one to CNC.

With version 9 I have been having VERY good luck in directly importing *.dwg files from Mechanical Desktop 5.0 and AutoCad 2000. Most of the issues I noted before were with MC 8. I have only had a couple of glitches in loading stuff into MC 9, deleting the paper space stuff fixed the problem.

Sometimes AUDIT or PURGE in ACAD helps.

Chris,

 

Try this method instead.

Use wblock, this allows windowing or feature picking exactly or only what you need; Of course you will be prompted for a drawing name as well.(this must be a different dwg)

 

Model space is always the preferred medium, paper space is fine for basic 2d stuff, wblock will work with either.

 

In my experience, I choose only to import the geometry that I need to get the job done; this method would likely suit your application best.
