I am working on automating the process of converting DWG files to PDF using AutoCAD. However, I am encountering some issues when executing the script. I would like to request your help regarding the following problems. Issue: In the AutoCAD script (.scr), even though I set the Portrait orientation, the output is being changed to Fit.

Script File: This issue arises when using an AutoCAD script in the .scr format.

Script:

-PLOT / No / Model / DWG To PDF.pc3 / ISO_full_bleed_A3_(420.00_x_297.00_MM) / Millimeters / Portrait / Scale to Fit / Y / QUIT

Error Message: Below is the error message received from the Design Automation API, specifically during the final phase (WorkItems) via the reportURL. The message shows the C command error and the orientation being set to Fit instead of Portrait.

Command: -PLOT Detailed plot configuration? [Yes/No] : Y ... Enter paper size or [?] <ANSI A (11.00 x 8.50 Inches)>: ISO_full_bleed_A3_(420.00_x_297.00_MM) Enter paper units [Inches/Millimeters] : M Enter drawing orientation [Portrait/Landscape] : Fit Command: C Unknown command "C". Press F1 for help. End AutoCAD Core Engine standard output dump. Error: AutoCAD Core Console output contains error(s).

Analysis: It seems that the issue arises from the C command error and the orientation being set to Fit instead of Portrait, which suggests there might be an issue with the script.

Requests: Could you confirm if there is a way to resolve the issue where Portrait orientation is being changed to Fit in the AutoCAD script (.scr)?

Please advise on why the C command error occurs and how to resolve it.

Are there any additional settings required in the AutoCAD script (.scr) to maintain the Portrait orientation correctly?

For your reference, I am using NestJS to convert the DWG file to PDF. Any additional help would be appreciated.

Thank you.

You're encountering the following prompt in your script:

Enter drawing orientation [Portrait/Landscape]:

This means AutoCAD is expecting a drawing orientation (Portrait or Landscape) at that point, but your script mistakenly provides something else—like FIT, which is not valid for this input.

Correct Usage Examples

Case 1: Minimal PLOT Script (No Configuration)

If you do not want to configure page setup details like paper size or orientation, you can skip them. In such cases:

  • Use No for the initial prompt.

  • If you don’t have a named page setup, leave that input blank (just press Enter between Model and .pc3 file).

  • This script simply sends the plot to file using default settings:


-PLOT\nNo\nModel\n\nDWG To PDF.pc3\noutput.pdf\nNo\nYes\n

Case 2: Full PLOT Script With Custom Configuration

If you want to specify detailed settings like paper size, orientation, scale, and style:


-PLOT\nYes\nModel\nDWG To PDF.pc3\nISO full bleed A3 (420.00 x 297.00 MM)\nM\nPortrait\nNo\nExtents\nFit\nCenter\nYes\nacad.ctb\nNo\n_A\noutput.pdf\nNo\nYes\n

  • Always provide Portrait or Landscape exactly at the orientation prompt.

  • "Fit" is intended for plot scale, not orientation.

  • _A in the end means As Displayed for shade plot settings

    This is how it gets run on APS Design Automation Engine
