[Stephen Cheesman]

Aaron:   You created an empty group... until you actually put objects inside that group, there can be no defined size to it, so GetGroupExtent_MVIEW returns rMIN and rMAX.   _______________ Geosoft Inc.

Here's a breif overview of what I'm doing,   View = Create_MVIEW(Map, "*Data", MVIEW_WRITEOLD); Extent_MVIW(View,MVIEW_EXTENT_MAP,MVIEW_EXTENT_UNIT_VIEW, Xmn,Ymn,Xmx,Ymx); DisplayReal_SYS("Xmn", Xmn); ... ...     //Right here, Xmn, Ymn, ... give the correct view extents   StartGroup_MVIEW(View, "Group1", MVIEW_GROUP_NEW); GetGroupExtent_MVIEW(View, "Group1", Xmn, Ymn, Xmx, Ymx, MVIEW_UNIT_VIEW); DisplayReal_SYS("Xmn", Xmn); ... ...     //Here I get Xmn, Ymn = -9.000e+0.31 and Xmx,Ymx = 1.0000e+032     Can someone tell me what I'm missing here in order to set the proper group extents       Aaron Balasch Sky Hunter Technologies Inc.
