How to get psltscale system variables of the specified layout

adn019LKFW — Wed, 10 May 2023 07:48:37 GMT

In the example drawing, psltscale of "layout1" is 1, and psltscale of "layout2" is 0. What is the correct way to get the psltscale in the specified layout. Function AcDbDatabase::psltscale() does not provide parameter for specifying layout or modelspace.

I think the only possible way without switching the layout is to analyze the DXF data of the AcDbLayout.

Here are screenshots of ArxDbg's command SNOOPDB:

You can retrieve the DXF resbuf list like this:

AcDbDatabase *pDB = acdbHostApplicationServices()->workingDatabase(); AcDbObjectId idLayoutDict(pDB->layoutDictionaryId()); ads_name dict; acdbGetAdsName(dict, idLayoutDict); struct resbuf* rb = acdbDictSearch(dict, L"Layout1", 0); if (rb) { // find 100, "AcDbLayout", 1, "Layout1", 70 and get the int value acutRelRb(rb); }
