Hi Bruce Reeves SRNS,
I am unable to find any better documentation for reference or locate a clean enough example specific to ACCUDRAW_UpdateRotation to provide, however maybe this starter code snip may provide another hint? If not let me know.
Your existing compiled V8i SS4 MDL applications should be binary compatible with either V8i SS4 or latest V8i SS10 released products.
Please let us know if you experience anything other.
Can you see if the test code snip below acts similar or helps?
DimensionStylePtr dimStyle = DimensionStyle::GetByName(L"TestDimStyle", *dgnFile);
if(NULL == dimStyle.get())
FYI. Development is taking a closer look at this and we will try to provide a code snip or determine if any enhancements may be needed to add to the public API/SDK. I will provide any feedback as soon as I receive it.
