I am using the personal free version of fusion on a Win11 computer and visual studio 2022.
I don't understand how the billboarding of Text is done within a custom graphic group of the fusion API.
"ScreenBillBoardStyle" is used!
I created the following script for testing it:
#include <Core/CoreAll.h>
#include <Fusion/FusionAll.h>
#include <Cam/CamAll.h>
using namespace adsk::core;
using namespace adsk::fusion;
using namespace adsk::cam;

{
if (cgGroup->item(iVQSentityIndex)->id().find("Frame") != std::string::npos)
{
cgFrameLines = cgGroup->item(iVQSentityIndex);
}
}
if (!cgFrameLines)
return false;
std::vector <double> vdvecCoords;

The following screen shows the result after starting the script:
After zoom and rotation to the X-Y Plane it will look like:
Now rotate the coordinate system 90 degrees around the Y axis clockwise:
You will see the "upper left corner of Frame" does not more fit to the left line of the Frame it is moved to the right.
Positioning the mouse pointer over the text results in the display of a blue text copy at the expected position.
Does anybody know why it is as it is?
Can anybody help so that the original black Text will be displayed at the position of the blue faded in Text?
Many thanks in advance for your help!
