Property Definition Formula to Get Attributes

Some properties return array of IDispatch which cannot be used in vbscript of formula definition, for instance the attributes returned by BlockReference are of VarType 8201 which is indicates an array of IDispatch pointers.

Using ConvertToVariantArray can convert it to array of variant so that the elements can be reached in vbscript, just like the way how it converts a point value (array of double).

NOTE: AutoCAD.Application.24 – AutoCAD 2021

AecX.AecBaseApplication.8.3 – AutoCAD Architecture 2021.

To know versions of various AEC libraries installed AutoCAD Architecture.

Take a note of ACADVER of your current installed AutoCAD.

AutoCAD Architecture	ACADVER	AEC Lib
2021	24.0	8.3
2020	23.1	8.2
2019	23.0	8.1

DWFXOUT: A Scriptable Command to Convert AutoCAD 3D Model to DWFX

 

There is an internal discussion that came up about scripting 3DDWF, the current command 3DDWF invokes a dialog to save the filename of the export model. The dialogs interrupt automation flow, to bypass and enable automation fluidity, here is the simple scriptable command.

The code employees function pointer (getSymbolAddress ) technique allows retrieving the address of an exported function from the specified dynamic-link library (DLL).

#define PUBLISH_DLL     _T("AcPublish.crx")

#define PUBLISH_SVC _T("AdskPublish")

typedef void (*EXPORT3DDWF)(bool, const ACHAR*, int);

 

void dwgoutcli(){

TCHAR fileName[MAX_PATH] = _T("");

int res = acedGetString(1, _T("\nPlease input the DWFX file name: "), fileName);

if (res != RTNORM){

return;

}

bool bCancelled = false;

int isFromCLI = 1;

if (!acrxServiceIsRegistered(PUBLISH_SVC)) {

    if (!acrxDynamicLinker->loadModule(PUBLISH_DLL, false, true))

    return;

    }

// Get the address of the export3dDWF service.

 

EXPORT3DDWF pFunc = (EXPORT3DDWF) acrxDynamicLinker->

getSymbolAddress(PUBLISH_SVC, "export3dDWF");

if (pFunc == NULL) {

assert(FALSE);

return;

}

pFunc(bCancelled, fileName, isFromCLI);

}

Plant3d: Important Changes in Python

This post is an attempt to reach to the developers who have not yet participated in AutoCAD Plant3d Customer Council.

As you might know, there was a Plant 3D Next Release Beta went live last month and one important change in the Beta is that Python scripts are in Python 3.7 instead of Python 2.7 (which is used in Plant 3D 2021 and earlier versions). The change is due to Python 2.7 went out of support (https://pythonclock.org/) on January 1, 2020 and the guidance from Autodesk security team for products to upgrade Python from 2.7 to 3.x.

For any of your customers or external users, they can click https://feedback.autodesk.com/key/plant3d to join AutoCAD Customer Council.
