Hello Erez,
Now that you have 'extinguished' the fire, we can go back to the begining.
PLT is not a type of conversion file, nor another drawing format. PLT is a generic denomination of a PLoTing file.
PLT is the way the plotter do understand what is drawn in a drawing sheet.
When you choose a printing machine you set it up to your computer via a program that understands both, the drawing editor and the printing routine of the printer (plotter). This is the printer "Driver".
So, all you got to do is to give to the plotter, the right orders, as in ancient days was told: pen up, pen down, run the paper forward, run the paper backward, etc.
What the PLT file does is roughly this.
You have not instructed the forum colleagues about which was your plotter and which is your Windows version. This informations would help a lot, and make easier all the communication. I've noted you were near to 'desperate', because people was not understanding your problem.
In fact all the guys were very interested to help you, but they couldn't in full.
In sequential steps you can do the following:
1) Obtain the driver software from the plotter manufacturer, in the updated version to 'your' plotter, for the Windows version you're using;
2) Enter on Windows/Start "Configuration" Printers -> Add new printer and configure the plotter with the "Door" as [File].
3) Entre on DataCAD 8 and in the Plotter menu access the "Configuration" option choosing the configured plotter to print;
4) Choose the paper size and exit Configuration dialog;
5) Enter in "Quick Layout" option and put the drawing extends into the paper size, and under the "Pen Table" menu, set the adjustements for colors and pen width;
6) With the option "Preview" ON, enter on "F1 Print/Plot" and see the result checking the informations;
7) If all is OK, just hit on "Print" and name the printing file (name.PLT), or, exiting the 'Preview' window, hit "F3 To File", and your PLT is done.
The problem with a PLT file is that you can't verify if it was all right or not. You will only know it after the printing is done. Can be too late.
As Neil Blanchard has suggested above, if you can find a PDF driver, you will be able to get the drawing sheet in PDF format, which will allow you to see and check the results in your display, and independently from the printer/plotter to be used to print the drawing.
I really hope this helps. Be welcome to our DataCAD Forum. I hope to see you again by here.
Thanks,
Miguel
