RealDWG problem with layouts and plot settings

tbrammer — Fri, 13 Jan 2017 14:15:23 GMT

I have a module called "DocManager" implemented in an ARX that creates a bunch of DWG files.
I have also ported the DocManager module to a RealDWG application.
The attached drawing AutoCAD.dwg was created by the ARX, RealDWG.dwg was created by the RealDWG-app.

The ARX-DWGs are ok:

Acad (AutoCAD) and the ACC (AutoCAD Core Console accoreconsole.exe) read them without complaints
Acad and ACC are able to "plot" their layout "DIN-A4" as PDF with the _-plot command
We can also plot them to PDF using Forge

The RealDWG-DWGs have some issues:

When I try to run ACC with the DWG it says: "ERROR: Something went wrong. ErrorStatus=53." and quits.
When I open them in Acad, a dialog pops up an says: "Drawing must be recovered. Errors found" (translated from German). I have to click [Recover]. Than a dialog says: "AUDIT didn't find any errors". The drawing appears and looks ok. Than I can plot it as PDF with Acad. If I save it I can also load and plot it as PDF with the ACC.
Plotting to PDF via Forge works - but the layout isn't scaled correctly

What is going on here? It looks as if Acad "repairs" something that is missing in the RealDWG application.
I don't know how I can find out what is wrong with the RealDWG DWGs. I suppose it has something to do with the layout initialization/validation.

In RealDWG I have to write my own AcDbLayoutManager / AcApLayoutManager. I named my class "imosRealDwgAcDbLayoutManager".
My acdbHostApplicationServices()->layoutManager() returns an instance of imosRealDwgAcDbLayoutManager.
There are some methods I have implemented as dummies, because I don't know how to write them:

void imosRealDwgAcDbLayoutManager::setDefaultPlotConfig(AcDbObjectId layoutBTRId)
void imosRealDwgAcDbLayoutManager::updateCurrentPaper(Adesk::Boolean zoomToPaper /*= FALSE*/)
void imosRealDwgAcDbLayoutManager::updateLayoutTabs()

Also my method AcDbPlotSettingsValidator* HostApp::plotSettingsValidator() const currently returns NULL because I have no Idea how to implement an AcDbPlotSettingsValidator. So in RealDWG my code:

    AcDbPlotSettingsValidator* pPltValid = acdbHostApplicationServices()->plotSettingsValidator();
    if (pPltValid)
    {
        pPltValid->setCanonicalMediaName(pNewLayout, chrMediaName);
        pPltValid->refreshLists(pNewLayout);
    }

won't do anything. How can I implement these methods?
Or is there an AcDbPlotSettingsValidator in RealDWG that I can use?

It may be important to say, that the DocManager creates, populates and saves AcDbDatabases that are not assigned to an AcApDocument.
They are also not the acdbHostApplicationServices()->workingDatabase().
I use code from here to copy plotsettings from one template DWG to my target DWG.

Any help and ideas are appreciated.
