【转帖】entities coordinates in ocs not wcs
 

entities coordinates in ocs not wcs?
entities coordinates in ocs not wcs?
i wish to get and set entities points in ocs not wcs.
is there a general way the convert all the set and get routines to be in ocs instead of wcs?
for example:
oddbtext position point:
oddbtext:: position() return the position in wcs.
i need it in ocs, what do i need to do?
oddbtext:: setposition() claim to be in wcs but it seems be in ocs.
maybe because the set the normal after i set the position?
to convert between ocs and wcs you can use odgematrix3d functions planetoworld() and worldtoplane() which make transformation matrix from normal.
in dwg and dxf files and at run-time text position is stored in ocs. and get/setposition() work in wcs. so in setposition() wcs point is converted to ocs according to normal. the normal should be set first. if normal is (0,0,1) ocs and wcs are the same.
this is a bit strange but we made it to be compatible with objectarx behavior.
