How to prepare a plot file in HPGL format from Autocad

The Quality Assurance Plan for the LHC Project requires that drawings supplied by collaborating Institutes and by companies be delivered in Hewlett Packard Graphic Language (HGPL) format, to be stored in the CERN Drawings Directory. (see the document LHC-PM-QA-306.00 "DRAWING PROCESS - EXTERNAL DRAWINGS", chapter 8).

The procedures below explain how to configure a plotter and create plot files in the correct format using AutoCad R13 or AutoCad R14, or AutoCAD R2002. They are intended for collaborating Institutes and companies outside CERN.

What do you want to do:

AutoCAD R13

Configure HPGL plotter for AutoCAD R13

Set up pen assignements for HPGL Plotter in version 13

Produce a plot file from AutoCAD 13

 AutoCAD R14

Configure HPGL Plotter for AutoCad R14

Set up pen assignements for HPGL Plotter in version 14

Produce a plot file from AutoCAD 14

AutoCAD 2002

How to prepare a HPGL file from AutoCAD


AutoCAD 13:

To configure a HPGL Plotter.

From Options Pull Down Menu choose Configure:

Or type CONFIG at the command line.

Press ENTER until the Configuration Menu is displayed in the Text Window.

Enter 5 at the command line to choose Configure plotter

At the Plotter Configuration Menu choose 1 to add a plotter configuration. The two lines above the Plotter Configuration Menu shows the current plotter configuration.

A list of available plotters is displayed at the screen. From this list choose a Hewlett Packard (HPGL) plotter.

A list of supported models is displayed at the screen. From this list choose the model HP7585B.

Set the port time out to 30 sec.

Select Parallel LPT1 as your port for the plotter.

AutoCAD displays a list of the current settings. Enter <N> to continue configuration or enter <Y> to go back and make changes to the settings.

AutoCAD then prompts for a description of the plotter: Save the settings as HPGL 7585B.

Exit Plotter Configuration and Configuration Menu by entering 0 twice.

AutoCAD then ask if you want to keep configuration changes. Enter <Y>.

 


To setup your newly configured HPGL Plotter with the correct pen assignments in AutoCad R13:

First download the file CERNP_HP.pcp from the WEB. Save it anywhere convinient to your self. This file contains information about the penassignments, and will be used to associate screen colours with pen widths for the plotter configuration. You will be asked to point to the file at a later stage in the printer setup sequence.

From File Pull down Menu choose Print:

The Plot Configuration Dialog box is displayed:

Click the "Device and Default Selection" button.

From the Device and Default Selection dialog box choose the HPGL Plotter you want, then click the "Get defaults from file" button.

 

Browse to the file CERNP_HP.pcp which you downloaded earlier.

Click OK until all dialog boxes are closed.

You have now configured a HPGL plotter and set the pen assignments to be in accordance with CERN standards.

 


To produce a plot file from AutoCAD R13.

From File Pull Down Menu choose Print

 

In the Plot Configuration dialog box choose Plot to file

Click the button: File Name and specify the directory and the file name you want to plot to. AutoCAD always gives the extension .plt to plot files. A plot file can be plotted later without using AutoCAD.

Choose other parameters such as metric paper size and scale etc. according to your needs and press OK, AutoCAD will then create a plot file of your drawing.

 


 AutoCAD 14:

To configure a HPGL Plotter.

From Tools Pull Down Menu choose Preferences:

You can also acces the Printer Setup dialog box from File Pull Down Menu by choosing Printer Setup.

Click the Printers Tab and click the New button:

In the list of available plotter drivers choose a HPGL plotter, and enter a name for the plotter in the box below the list of plotters ( the name you want to use for identifying this plotter) and press OK.

From the list of supported models choose HPGL 7585B.

The questions which follow from AutoCad will vary a bit depending on your configuration, but you should just answer in accordance with your PC configuration.

Select Parallel LPT1 as port for your plotter. If you are asked to set seconds for port time out choose 30 seconds.

When you have entered all necessarry information, AutoCad will return you to the Printer Setup dialogbox. To activate your new plotter configuration, highlight the plotter describtion and press "Set Current" button.

Just above the printer selcetion window, you see which plotter is current, and below the printer selection window your se the configuration of the highligthed plotter.

When you have selected the correct plotter exit the Printer Setup dialog box by clicking OK.

In the Print/Plot Configuration dialog box click the Device and Default Selection button.

In the Device and Default Dialog Box highlight the HPGL plotter you want to set the penassigmnets for.

Then click the Merge button

Browse to the file CERNP_HP.pcp which you downloaded earliere, click the Open button and click OK unitl you are back in the Print/Plot Configuration dialogbox.

You can check that the pen assigments are right by clicking the Pen Assignments button in the Print/Plot Configuration dialog box and see that the penwidth vary.

 


 To produce a plot file from AutoCAD R14.

From File Pull Down Menu choose Print

 

In the Plot Configuration dialog box choose Plot to file

Click the button: File Name and specify the directory and the file name you want to plot to. AutoCAD always gives the extension .plt to plot files.

Choose other parameters such as metric paper size, scale etc. according to your needs and press OK, AutoCAD will then create a plot file (*.plt) of your drawing and save it in the directory you have specified. A plot file can be plotted later without opening AutoCAD.
