Re: how to set snappable/non-snappable attribute?

I just wondered if there is a more elegant way to do this since modifying elements directly in this fashion seems to be discurraged as of lately.

Ray:

In V8 2004 edition, I did it thusly:

      mdlElement_read(dgnBuf,ACTIVEMODEL,elemAddr[j]);
      
      /* 0==snappable, 1==not snappable */
      /* .isGraphics must be true for .dhdr to be valid */
      if (dgnBuf->hdr.dhdr.props.b.s  && (dgnBuf->hdr.ehdr.isGraphics))
         {     
         dgnBuf->hdr.dhdr.props.b.s=FALSE;
         mdlElement_rewrite(dgnBuf,NULL,elemAddr[j]);
         }

Speaking of snappable, does anyone else remember when IGDS shapes were NOT snappable?  And when shapes were identified by a data point INSIDE, not ON, the shape element?

What is the mdl function for setting the snappable attribute of an element?

Thanks
