I‘m a begginer of objectarx development learner,and I built a new project want to create a simple box ,here is my code

#include "stdafx.h" #include "CreateSolids.h" void CreateSolids::Init() { acedRegCmds->addCommand(_T("CreateSolidsCommands"), _T("CreateBox"), _T("CreateBox"), ACRX_CMD_MODAL, CreateBoxFunction); } void CreateSolids::Unload() { acedRegCmds->removeGroup(_T("CreateSolidsCommands")); } void CreateSolids::CreateBoxCommnad() { CreateBoxFunction(); } void CreateSolids::CreateBoxFunction() { // box AcDbDatabase* pDb = acdbHostApplicationServices()->workingDatabase(); AcDbBlockTable* pBlockTable; if (pDb->getBlockTable(pBlockTable, AcDb::kForWrite) != Acad::eOk) { acutPrintf(_T("Failed to get Block Table.\n")); return; } AcDbBlockTableRecord* pModelSpace = nullptr; if (pBlockTable->getAt(ACDB_MODEL_SPACE, pModelSpace, AcDb::kForWrite) != Acad::eOk) { acutPrintf(_T("Failed to get Model Space.\n")); pBlockTable->close(); return; } AcDb3dSolid* pBox = new AcDb3dSolid(); if (pBox->createBox(10.0, 10.0, 10.0) != Acad::eOk) { acutPrintf(_T("Failed to create box.\n")); pBox->close(); pModelSpace->close(); pBlockTable->close(); return; } pModelSpace->appendAcDbEntity(pBox); pModelSpace->close(); pBlockTable->close(); }

errors like this :

try adding this in your StdAfx.h, or somewhere in your code if you don't have that

#pragma comment( lib , "AcPal.lib" )
