Hi,
I have problem when using mdlElement_display(). I have attached code snippet on this mail. I am trying to display line element in the dgn but not displaying. The following code works in Microstation V7 very well but not working in Microstation V8 XM Edition.I don't know problem where occurs will you please help me.
Code Snippet :
int draw_line(DPoint3d pnt[])
{
if(mdlLine_create(&line_elm,NULL,pnt)!= SUCCESS)
{ print_error(MS_CREATE_ERROR, "", TRUE); return FALSE; }
mdlElement_display(&line_elm, NORMALDRAW);
return TRUE;
}
Thanks & Regards,
V.Sathish.

From MicroStation XM the graphic subsytem changed. We MDL programmers no longer need to call mdlElement_display() (it's a no-op). The new graphic system takes care of element display automatically. However, it should not be a problem to leave it in your code for compatibility when compiling with an earlier version of V8.
What leads you to suspect that mdlElement_display() is a problem?

I am not facing any problem in mdlElement_display. But In V7 this code displays the line wheb mouse button clicking. Not shows in XM Edition. it shows hidden line. I want display the line for temporary not using mdlElement _add function.
} Help me
Dear jon,
mdlElement_add function without using i want to display the line element. Because Our functionality we construct a temporary line finally we call mdlLinestring_create function. So please tell me without using mdlelment_add function.
sathish: Dear Jon, Still line element not highlighting. ... msTransientElmP = mdlTransient_addElement (msTransientElmP, &line_elm, 0, 0x00ff, DRAW_MODE_Normal, 1, 1, 1);
Dear Jon,
Still line element not highlighting. ... msTransientElmP = mdlTransient_addElement (msTransientElmP, &line_elm, 0, 0x00ff, DRAW_MODE_Normal, 1, 1, 1);
Why should it highlighting? You are creating transient as normal draw not hilite.
Attached is some sample code that uses the transient element descriptor.

I know that you want to display the element temporarily. However, you have told us that you can't persuade the transient functions to do what you want. I asked you to use mdlElement_add in order to be certain that you really are creating a line element and that the line appears in the right place.
None of us can see what you are doing, or how MicroStation behaves with your MDL code. If you want help in diagnosing your problem, then you have to cooperate.
Hi all,
From still i will not get the solution for displaying element. I have attached zip file on this mail. This mdl project line displaying in V7 version but not in V8 XM Edition. Please modify this attached code give to me. Without using "mdlElement_add" function.
Give me a solution.
It's not clear that you have attempted to implement the transient code provided by Mark.
void Draw_TerminalLine(void) { mdlState_startPrimitive (get_Draw_TerminalLine_point, get_Draw_TerminalLine_reset, 0, 0); } /*-----------------------------------------------------------------------------------------------*/ static void get_Draw_TerminalLine_point(Dpoint3d *ppt,int view) { MSElement el; DPoint3d dpPnt[2]; DgnModelRefP modelRef ; dpPnt[0].x = dpPnt[0].y = 10.0; dpPnt[1].x = dpPnt[1].y = 20.0; dpPnt[0].z = dpPnt[1].z = 0.0; mdlLine_create( &el, NULL, dpPnt ); mdlElement_display( &el, NORMALDRAW); exit(0); }
Your code creates a line element, displays it, then exits. You have (i) not added the line element to the model, and (ii) you have not attempted to create a transient element. There is nothing to display.
I am really sorry say still line element not displaying after adding mdlTransient_addElement function. Updated code attached on this mail.

Thanks very much for replying.
Without mdlElement_add function working in Microstation V7 environment.
You did not answer Jon's question, though:
Have you tried using, as already suggested, mdlElement_add to be sure that you create a valid line?
