DrH/Changelog

What changed, and when.

This page tracks the manager itself. Tool-level changes show as an updated date on each card in the library.

9 September 2026library

Drop Manhole Builder published, and the flagship tools get their marks

  • New tool — DROPMH, Civil 3D. Builds a backdrop drop structure wherever an incoming pipe lands too high above the outgoing invert, as real network geometry that still schedules and still reads in profile. Threshold and sizes come from your own drainage standard.
  • The four flagship tools — DROPMH, DRYNET, C3D2RVT and NWC2DXF — now carry their own marks on the library cards and on the home page, so they are recognisable in the panel and in the catalogue.
  • Nothing to reinstall. Press Update in the panel and DROPMH arrives matched to your host year.
5 September 2026v1.0.0

First public release

  • One panel across Civil 3D, Revit and Navisworks, with the same import flow and the same naming in every host.
  • Local folder imports and the online library, for LISP and DLL packages alike, with .addin sidecars picked up automatically.
  • Host-aware loading from 2021 through 2027, each package matched to the runtime channel its host expects.
  • Icon sidecars: a PNG named after the package becomes the button icon on the ribbon.
  • Import, load, update and run activity all write to one log on the desktop, so a failure is traceable rather than mysterious.
  • Manager updates leave installed tools untouched.

Updates are the whole point.

A Pro year covers every release on this page and every tool published alongside it, including support for Autodesk years that ship mid-licence.
