DWG Cleaner Free is a free utility for batch cleaning AutoCAD DWG drawings.

The program is designed for situations when you receive “dirty” DWG files from architects, contractors, engineers, clients, or other companies. These drawings may contain unnecessary layers, unused blocks, extra layouts, duplicate objects, old styles, frozen or hidden layers, non-plot layers, and other CAD clutter.

DWG Cleaner helps you prepare drawings faster for work, review, sharing, archiving, or further processing.

Boundary2Coords is a small desktop tool for surveyors and engineers who work with legal descriptions of land parcels.

Instead of manually computing coordinates from bearings and distances, you can enter the traverse once and immediately get corner coordinates, area and closure information, and a clean DXF ready for CAD.

A small Python tool for land surveyors.

Runs in the console and supports:

converting bearings (N/S–E/W) ↔ azimuths (0–360° clockwise from North)

It allows you to quickly organize layers in DXF drawings:

✅ rename layers in bulk

✅ apply prefix/suffix or find & replace

✅ merge multiple layers into one

✅ split layers by colors, linetypes, or block names

✅ import/export mapping and save projects for reuse

After trying many popular time trackers, I realized none of them fully matched how I actually work. Too complex, cloud-dependent, or simply overkill.
