Tech Tip: AutoCAD DWG File Versions

[Webby]

You can tell what Version of AutoCAD a DWG file is from by opening the file in an ASCII text editor (e.g. Wordpad). The first 6 characters are readable, and the rest will look like garbage.

This chart is correct to the best of my knowledge:

AC1006 - AutoCAD R11

AC1009 - AutoCAD R12

AC1012 - AutoCAD R13

AC1014 - AutoCAD R14

AC1015 - AutoCAD 2000

AutoCAD 2000 DWG will be supported in the Mastercam V8 optional DWG Converter.

I have a customer who has Mastercam 7.2c and the dwg rev.F converter. He is trying to send a dwg/dxf file to a company to plot his file for him, and it is not working correctly. This company has just updated its Autocad to ver. 2000, and the plotter from HP 750c to HP 812.

With previous ver. of Autocad the plots worked fine.

I was wondering if there is a work-around for him until V8 is released?

[Webby]

Mastercam V7 only writes out ACAD 14 files. The company should be reading in the files as ACAD 14. Mastercam V8 will support ACAD 2000.

If the file reads in correctly, but does not plot, it would appear to be an AutoCad or plotter issue, would it not?

Provided more details on where the actual problem lies if you could.

Yes, it is an Autocad/plotter problem. They are now looking for the correct windows driver for the plotter.
