CAD And Civil3D Addin Manager

🕒 Published at:



Usually, when developing and debugging an addin with Autocad or Civil3D API, user has to close & re-open Autocad or Civil3D each time he/she modifies the addin code and wants to re-compile. But with Add-In Manager, user can modify and run the Addin. directly without closing & re-opening Autocad or Civil3D again and again.This is a next branch from Revit Addin Manager to support multiple platform API for developer. With current technology, you can use Hot Reload to speed it up.But try this project it will be faster with any Addin.

Some feature include:

  • Add-in manager
    • AddInManager Manual : Use for normal process load/unload addin
    • AddInManager Faceless : use for load last process before addin without UI
  • Allow user know whether plugin can load successfully or not.
