// --------------------------------------------------------------- // Project: IdwUtilBatchExport // Target: .NET Framework 4.8 (or .NET 6+ with netstandard2.0) // --------------------------------------------------------------- using System; using System.IO; using NXOpen; // Core NX Open namespace using NXOpen.UF; // Needed for low‑level UF calls using IdwUtilLib; // <-- The COM wrapper generated from idwutil_600.dll

The file is a background process associated with IDrive , a cloud backup service. It is primarily a utility used to manage data transfers and system synchronization for the IDrive application. Key Characteristics

| Symptom | Likely Cause | Fix | |---------|--------------|-----| | FileNotFoundError: idwutil_600.dll | DLL not on the system PATH or installed in a non‑standard location. | Add the folder containing the DLL ( …\NXBIN ) to the environment variable, or call the executable with a full path. | | 0x80070005 (E_ACCESSDENIED) when creating COM object | Running as a non‑admin user on a machine where the DLL is registered for admins only. | Run your script as Administrator or re‑register the DLL for “Everyone” with regsvr32 /s "C:\…\idwutil_600.dll" (requires admin rights). | | License error: No NX license available | Headless session started without a valid NX runtime license. | Ensure a floating or per‑seat license is reachable, or set the environment variable UGII_LICENSE_FILE to point at your license server. | | Exported PDF is blank or missing sheet data | The drawing contains broken view references or the sheet’s “display” flag is off. | Open the .idw in the GUI, run “Update All Views”, save, then re‑run the batch. | | rc = 31 from ExportPdf | Invalid scale factor (negative or zero). | Use a positive floating‑point number (e.g., 1.0 ). | | “ The specified module could not be found ” on Linux | You tried to run the Windows DLL on Linux. | On Linux, use the NX Open C++ API instead; idwutil_600 is not shipped for Linux. | | Crash on 64‑bit machine with a 32‑bit DLL | Mismatch between NX installation (64‑bit) and DLL (32‑bit) . | Install the correct 64‑bit version of NX (or use the 32‑bit “NX Compatibility Mode” if you must stay on 32‑bit). | idwutil_600

If you need (loop over many drawings, modify view properties, etc.), load the DLL with the regular NX Open .NET API. The DLL exposes a COM‑visible class called IdwUtil . Below is a minimal C# console sample that:

: This feature might assist in the planning phase of well construction, helping to identify potential drilling hazards, optimizing well trajectory, and ensuring compliance with regulatory requirements. | Add the folder containing the DLL (

It handles automated backup tasks and data integrity checks.

: Some users have noted the process responsible for massive data uploads (upwards of 2TB) even when no external drives were connected for backup, leading to concerns about bandwidth usage. Security and Verification | | License error: No NX license available

( oleview.exe ) to see the type library name – usually IdwUtil .

💡 You can verify if it's the real process by right-clicking it in Task Manager , selecting "Open file location," and ensuring it resides in an IDrive-related directory.
