What's new in MED

Current release MED2026 2026.0.0925a Sep 25, 2026

The AutoCAD electrical and controls tools I've built over decades of real project work. Free and open source. Draw it once in 2D, get the 3D model and the material list from the same drawing.

Same drawing. Three outputs. Nobody retypes anything.

Details, plans, 3D models, material data. Each one answers a different question for somebody on the job: the designer, the estimator, the crew in the field. MED keeps them all coming from the same drawing.

2D drawing

Draft the run the way you always have. MED puts the material data on the entities as you draw.

3D model

The same run, modeled in 3D. No second drawing to keep in sync.

Material list

The BOM comes straight from what's in the drawing. Browse it, filter it, export it.

Selecting a MED tray in Navisworks shows its MED properties
Coordination

Your MED data shows up in Navisworks

Select a tray in Navisworks and the MED properties are right there: description, length, the same data you built in AutoCAD.

Handy when you're coordinating and don't want to bounce back to the drawing just to check something you already tagged.

2026.0.0925a release notes

  • Registration email fix. The optional install registration page no longer rejects addresses like first.last@company.com. Fixed in both Setup and Patch.
  • Safer patching. The Patch checks that MED is actually installed before it touches anything, and warns you before it installs over a newer version.
  • Profile repair. RestoreMEDProfile.cmd rebuilds or repairs the MED2026 AutoCAD profile if it gets messed up.
  • 3D tray export ignores running OSNAPs and writes a .medprops.json sidecar with the MED properties next to the DWG.
  • No surprise reboots. Setup and Patch stopped asking for a restart because of unrelated pending file renames (printer drivers and such).
Coming next · MED2026 2026.0.1005a

3D conduit, a 3D block library, and a whole new ribbon

This is the biggest build since launch. It's still a work in progress, but here's what's on the bench.

WIP preview 2026.0.1005a is a pre-release I'm still testing. The 3D features, the new ribbon and the docs are being reviewed. The Download button above gets you the current release (0925a) until this one is promoted.
MED 3D rigid conduit bodies: LB, LBD, LBY, BLB, TB, T, C, LL, EYS, EYD, GUAL, GUAT
3D conduit bodies

Place the fitting. Get a sized 3D body.

Fittings placed from the menu become sized 3D bodies at the conduit elevation, and the conduit trims back to the hub faces. Dimensions come from Crouse-Hinds / Eaton catalogs where they're published.

Mirrored inserts get flagged ("re-insert, do not mirror") instead of being modeled wrong.

MEDMAKE3D

One command builds the whole model

Tray and tray fittings, then conduit, conduit bodies and cable. It asks once for Dwg or Layer output and tells you what it made, flagged and skipped.

Bends are true fillets, and solids are sized by conduit type, so 1/2" EMT isn't drawn as rigid.

GUAL conduit outlet bodies in six sizes, 1/2 inch to 2 inch
GUA fittings + MEDCBGRID

GUA boxes, 1/2" to 2", checked against real DWGs

GUAL / GUAT / GUAX in 3D. MEDCBGRID lays out every fitting orientation at drawing scale, so you can check them all before you commit to a model.

MED3DLIB · 385 blocks

A 3D block library that docks right in AutoCAD

385 3D blocks in 22 categories: lighting, power equipment, conduit fittings, strut, cable tray, J-boxes, structural, detectors and more. Search, thumbnails, drag and drop to insert.

Pages from the MED2026 User's Guide draft
Docs

A 109-page User Guide and full command reference

Tutorials, a new 3D Block Library chapter, a command appendix and an AutoLISP reference. It's still a draft with items marked [VERIFY], so treat it that way.

The new MED Main ribbon tab: Mode, MED Data Tools, 3D and Text panels
New MED ribbon

MED Main stays up. Plan, Detail or Wiring follows what you're drawing.

MEDPLAN, MEDDETAIL and MEDWIRING flip the tab to match your drafting mode (MEDRIBBONMODE). MED Records, MED Change, BOM, MED 3D Library and Make 3D are all one click away.

All of 1005a in one loop

3D conduit bodies, the data tools, GUA fittings and MEDCBGRID, MED3DLIB, the new ribbon and the User Guide.

Also in this build

Parametric MOTOR (20 sizes, 0.5–200 HP, 2D for now) · BOMSS is back · Browse BOM opens MEDSHOWBOM · MEDDEBUG logging · a stack of pulldown and block fixes · the Patch now updates all of Support, so ribbon and menu changes reach patched seats.

3D disclaimerMED 3D models are approximations, not copies of manufacturer specifications; users must verify all dimensions.

  • Tray export writes a {dwg}.medprops.json sidecar beside the saved DWG.
  • Setup and Patch no longer prompt for a reboot over unrelated pending file renames.
0904aLaunchSep 10, 2026MED goes open source: first public Windows installer
  • First public MED2026 installer. Default install C:\MED2026, SQLite seed database (SQL Server optional).
