Check If SOLID3D Has Valid Shape Manger Object

By Madhukar Moogala

Having Solid’s with invalid shape manager object is always prone to fatal crash it is suggested to check the sanity of underlying shape manager object for a given AcDb3dSolid.

You can check using SOLIDEDIT command.

 

;51 is Handle of the solid entity
(command "._solidedit" "B" "C" "51" "X" "X")

With API

Acad::ErrorStatus selectEntity(AcDbObjectId& eId)
{
    ads_name en;
    ads_point pt;	
    ads_entsel(_T("\nSelect an entity: "), en, pt);
	return acdbGetObjectId(eId, en);
}

void solidCheckForValidASM()
{
	AcDbObjectId solId = AcDbObjectId::kNull;
	if (!eOkVerify(selectEntity(solId))) return;

	AcDbSmartObjectPointer pSolid(solId, AcDb::kForRead);
	if (!eOkVerify(pSolid.openStatus())) return;	

	//Get access underlying raw pointer
	if (nullptr == pSolid.object()) return;
	std::unique_ptr pEnt(new AcBrBrep());

	//pass raw pointer to BREP API
	if(pEnt->set(*pSolid.object())!= AcBr::eOk) return;
	
	bool isGoodAsmBody = pEnt->checkEntity();
	if (!isGoodAsmBody)
	{
		acedAlert(_T("Null or Invalid Shape Manager"));
	}

	return;
}

RealDWG and Civil3d Object Enabler

By Madhukar Moogala

If you are planning to extend your realDWG app to support C3D drawings, then it is must for your app to have access to Civil3D dbx modules to avoid proxy objects.

The installer of Civil C3D OE 2018 was changed, it’s independent any other product now. Different with OE 2017.

From 2018 onwards OE installs files and registries to fixed location.

File: C:\Program Files\Autodesk\Autodesk AutoCAD Civil 3D 2018.1 Object Enabler 64 Bit

Registry: HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\ObjectDBX\R22.0

RealDWG  always loading .dbx from above registry key.

In theory, OE 2018 is available for all RealDWG application (with consistent version), We only verify the official target products (AutoCAD and family, InfraWorks, Navisworks Manager and simulation).

How to deploy Civil3d Object Enabler with our application ?

Civil3d Object Enabler is a free application, your free to redistribute along with your application.

How do I distribute the AutoCAD Civil 3D Object Enabler install?

The AutoCAD Civil 3D Object Enabler is free, and can be distributed to anyone who wants to view the civil objects in your drawings. However, the AutoCAD Civil 3D Object Enabler alone cannot display the objects in your drawings. You must have an installed copy of one of the Autodesk products listed in Using the AutoCAD Civil 3D Object Enabler.

One approach is to extract Civil3DOE.MSI from Civil3D_2018_OE_64Bit.EXE which you have downloaded from web. You can use ‘dark’ tool from Wix toolset for extraction. And wrap the extracted MSI in to your application.

C:\Program Files (x86)\WiX Toolset v3.11\bin>dark D:\Crap\Civil3D_2018_OE_64Bit.exe -x D:\Crap\Civil3D_2018_OE_64Bit
