Methods of ucs(wcs)

When i try to set the current ucs by ucs name within the ucstablerecord, I found that the founction "acedSetCurrentUCS" doesn`t work. I wish to get more detail about ucs. How does the ucs work in objectarx,

Thank a lot.  And i`m a newer in objectarx learining. The code in that page that you provide confuse me. Maybe i have some misunderstandings about wcs and ucs. Could you give some recommends to help me getting deeper to understand the relationship between wcs and ucs.  Thank u very much.

Thank you very muck, I just want to know how to implement the founction: druing the process of drawing, i just need type a shortcut to set the current ucs instead of clicking the viewcube and selecting the named ucs or wcs to set the default ucs or wcs.

You need to get the view matrix and feed it to acedSetCurrentUCS

There’s a thread here https://forums.autodesk.com/t5/objectarx/need-to-mimic-ucs-v-command/m-p/5197755

This probably doesn’t do what you want, but so you have an idea

    //#include "gs.h"
    //#pragma comment(lib, "AcDrawBridge.lib")
    static void ArxBrxTest_doit()
    {
        resbuf cvport;
        acedGetVar(_T("CVPORT"), &cvport);
        AcGsKernelDescriptor desc;
        desc.addRequirement(AcGsKernelDescriptor::k3DDrawing);
        const AcGsView* pView = acgsObtainAcGsView(cvport.resval.rint, desc);
        acedSetCurrentUCS(pView->viewingMatrix());
    }

edit, might be better to send command "UCS" "V"
