Power Line Sag Calculator Web is designed for surveyors, civil engineers, utility field personnel, and other specialists who need a fast preliminary evaluation of an overhead conductor between two attachment points.

The program uses a catenary curve instead of a simple circular arc. A catenary is a more physically appropriate geometric model for a flexible uniform conductor suspended between two points.

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.

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
