Function Entry: ARXLOAD

Name

arxload

Class

Application-handling function

Syntax

(arxload appname)

Arguments and Values

  • appname: ObjectARX application designator

Autodesk documents the actual signature as: 

(arxload application [onfailure])

with:

  • application — string naming the ObjectARX executable or bundle
  • onfailure — expression to evaluate if loading fails

Description

Loads an ObjectARX application.

Return Values

String naming the application if successful.

If loading fails and onfailure is supplied, Autodesk documents that the value of onfailure is returned; otherwise an error is reported.

Side Effects

Loads host extension code into the running CAD session.

Compatibility

Strongly host-specific and outside portable core AutoLISP semantics.

Availability

  • AutoCAD 2026: documented (per Autodesk reference page).
  • BricsCAD V26: presumed compatible (no contradicting page found).
  • Status: AutoCAD documented; BricsCAD presumed-both pending Phase 4 verification.

Notes

  • Autodesk documents that the file extension may be omitted: .arx on Windows and .bundle on macOS.
  • Autodesk documents that a full path is required unless the application is in the support-file search path.
  • Autodesk documents that loading an already loaded application is an error, and suggests checking with arx first.
  • Autodesk documents secure-mode restrictions through SECURELOAD and TRUSTEDPATHS.

Compatibility

Supported on Windows and macOS, not Web.
