ZoomPrevious in Pure ObjectARX code
« on: March 04, 2014, 09:51:11 PM »
Hello,

  I'd  like to know if there is code for a purely ObjectARX ZoomPrevious method from AutoCAD's COM API?

Thanks,

save yourself the headache:

acadDoc.SendStringToExecute("ZOOM p\n", false, false, false);

While it might seem like a hack, you are implementing it fast and safely avoiding possibly buggy code to do something that acad could probably do quicker albeit in a roundabout way.

interestingly, AutoDesk use a similar code in their ARX samples

Code - C++: [Select]
  1. acedCommand(RTSTR, _T("_ZOOM"), RTSTR, _T("_Extents"), 0);    // zoom to a reasonable spot
