Readme for AutoCAD Mechanical 2025 SDK

The SDK contains libraries, header files, documentation and samples for AutoCAD Mechanical APIs.

 

Development Environment

Microsoft Visual Studio 2022 should be used when compiling projects for use with AutoCAD Mechanical 2025.

 

ObjectARX

ObjectARX can be downloaded from http://www.autodesk.com/objectarx.

The ObjectARX include and library directories are specified in the file \acadmapi\inc\acadmapi_CommonCfg.vsprop for the samples in ACADMAPI. Rename these directories appropriately if ObjectARX is installed in a different location to the SDK.

ObjectARX projects that currently link with acad.lib should also link with accore.lib and ac1st25.lib.

For .NET projects, AcCoreMgd.dll should be referenced.

Refer to readme for ObjectARX for details on the changes.
