Read and set Dimension style from current drawing file.

jlobo2 — Mon, 01 Jul 2019 18:58:21 GMT

How do I read, from a Dimension Style table in the current drawing, and set it to an object to be used later for drawing?

The code below, returns object id as null. Am I missing something here?

Thank You for your help in advance.

AcDbDimStyleTable *pDimensionStyleTbl;

theDb->getSymbolTable(pDimensionStyleTbl, AcDb::kForRead);
pDimensionStyleTbl->getAt(_T("_STANDARD"), idDimensionStyleStandard);

@jlobo2

You have to use AcDbDatabase::dimStyleTableId for get AcDbObjectId of AcDbDimStyleTable

Also you have to check name _STANDARD (maybe STANDARD without underscore)

Thank You for your response.

The underscore, is the part of the name in the current drawing.

Not sure, what did you mean by AcDbDatabase::dimStyleTableId ?

	AcDbDatabase::dimStyleTableId *tempDb;

Sample code:

static void ADSKMyGroupMyCommand() {
  Acad::ErrorStatus es;
  AcDbDatabase *pCurDb = acdbCurDwg();
  AcDbObjectId idDimStyleTable = pCurDb->dimStyleTableId();
  AcDbDimStyleTablePointer pDimStyleTable(idDimStyleTable, AcDb::kForRead);
  if ((es = pDimStyleTable.openStatus()) == Acad::eOk)
  {
    AcDbObjectId idDimStyleTableRecord;
    if ((es = pDimStyleTable->getAt(_T("_STANDARD"), idDimStyleTableRecord)) == Acad::eOk)
    {
      acutPrintf(_T("\nidDimStyleTableRecord=%x"), idDimStyleTableRecord.asOldId());
    }
    else
    {
      acutPrintf(_T("\npDimStyleTable->getAt() = %s"), acadErrorStatusText(es));
    }
  }
  else
  {
    acutPrintf(_T("\npDimStyleTable.openStatus() = %s"), acadErrorStatusText(es));
  }

}

@Alexander.Rivilis Thank You for your response.

I am receiving an error with AcDbDimStyleTablePointer pDimStyleTable(idDimStyleTable, AcDb::kForRead);

saying, that it's an undeclared identifier.

Which libraries are you using? I am using Object ARX, in Visual Studio. I only have the options below with the

AcDbDimStyleTable

Ok. Add line on top of file:

#include "dbobjptr.h"

@Alexander.Rivilis Thank You, but the id is still NULL. Not sure why.

Attach your dwg-file. What ObjectARX SDK version you use?

Re: Read and set Dimension style from current drawing file.

jlobo2 — Mon, 01 Jul 2019 20:38:33 GMT

We are using ObjectArx 2018 version. we have a template file setup. So all we are trying to do is read data from the template drawing file and use the data while drawing a new one.

I've created new dwg-file, created new Dimension Style with name _STANDARD and exec my code in this drawing - no error and valid AcDbObjectId:

jlobo2 — Mon, 01 Jul 2019 21:17:27 GMT

Ok.

Am sure we are missing some files.

In the code - AcDbDatabase *pCurDb = acdbCurDwg(); gives us an error, acdbCurrDwg is undefined.

Which header file should we include for this one?

Add:

#include "migrtion.h"

or replace acdbCurDwg() with acdbHostApplicationServices()->workingDatabase()

jlobo2 — Mon, 01 Jul 2019 21:24:17 GMT

ok,

now the error message is

Error (active)		identifier "acdbHostApplicationServices" is undefined

So, the first code snippet I posted, works on AutoCAD 2018 on Windows 8, but fails to work on AutoCAD 2018 on Windows 10. Any idea why?

No ideas. You have to debug your code.

P.S.: Error is due to your not include dbapserv.h

Best solution is create new project with ObjectARX Wizard 2018

jlobo2 — Mon, 01 Jul 2019 21:44:10 GMT

Yes, I believe that's the way to go. Was just debugging and bug fixing code for my colleague, who is no more with the company. I really appreciate your help. It saved me lot of research time.

@Alexander.Rivilis

I have this code in C#.NET to access the DimStyles on a different project.

It works well with users in one country, but not with another country.

Am I missing anything here?

DimStyleTable pDimensionStyleTbl;

using (Transaction acTrans = theDb.TransactionManager.StartTransaction())
{
      pDimensionStyleTbl = acTrans.GetObject(theDb.DimStyleTableId,
      OpenMode.ForRead) as DimStyleTable;
      idDimensionStyleStandard = pDimensionStyleTbl["Standard"];
}

pDimensionStyleTbl.Dispose();

Maybe "Standard" is renamed? If is easy rename dimstyle "Standard" to any other name with _RENAME command.

using (Transaction acTrans = theDb.TransactionManager.StartTransaction())
{
      DimStyleTable pDimensionStyleTbl = acTrans.GetObject(theDb.DimStyleTableId,
      OpenMode.ForRead) as DimStyleTable;
      try {
        idDimensionStyleStandard = pDimensionStyleTbl["Standard"];
      } catch {};
      acTrans.Commit();
}

I thought so, but its named as Standard.

What value of idDimensionStyleStandard after code execution?

@Alexander.Rivilis Any help to the question below. i would really appreciate it.

Make Dimensions Annotative from a Template in the drawing

The dimensions are not being annotative.
