Convert PJT to BLN

Understanding PJT and BLN file formats

PJT files are typically associated with project files used by various software applications, such as Microsoft Visual FoxPro or Primavera Project Planner. These files store project-related data, including tasks, resources, and schedules.

BLN files are boundary line files commonly used by Surfer (a popular mapping and surface modeling software by Golden Software). BLN files contain coordinate data that define boundaries, paths, or polygons for mapping and visualization purposes.

Why convert PJT to BLN?

Converting a PJT file to a BLN file is often necessary when you need to transfer project boundary or path data from a project management tool into a mapping or GIS application like Surfer. This allows for advanced spatial analysis and visualization of project data.

How to convert PJT to BLN

There is no direct, universal converter for PJT to BLN, as PJT files can vary in structure depending on the originating software. However, the general process involves exporting the relevant coordinate or boundary data from the project file and then formatting it into the BLN structure.

1. Export data from PJT: Open your project in the original software (e.g., Primavera or Visual FoxPro). Use the File → Export or File → Save As function to export the relevant data (such as coordinates or boundary points) to a common format like CSV or TXT.
2. Format data for BLN: Open the exported file in a spreadsheet editor (e.g., Microsoft Excel) or a text editor. Arrange the data to match the BLN file format, which typically starts with a header line indicating the number of points, followed by lines of X, Y (and optionally Z) coordinates.
3. Save as BLN: Save the formatted data with a .bln extension. Ensure the file structure matches Surfer's BLN requirements.

Recommended software for conversion

• Microsoft Excel or LibreOffice Calc: For editing and formatting exported data.
• Golden Software Surfer: For importing and verifying the BLN file.
• Notepad++ or any advanced text editor: For manual editing of the BLN file structure.

For advanced users, custom scripts in Python or VBA can automate the conversion process if you frequently need to convert PJT data to BLN format.

Summary

While there is no one-click solution for PJT to BLN conversion, exporting your project data and manually formatting it for BLN import is straightforward with the right tools. Microsoft Excel and Golden Software Surfer are highly recommended for this workflow.
