Question

Appologies for asking such a simple question: 
 given that I have a pointer to a MSElement as below, how could I get a pointer to a MSElementDescr? Since MSElementDescr is dynamically created, I'm assuming that there is some mdl funciton that takes in a MSElement paramter and provided a pointer to the element descriptor after creating the descriptor. But I have not been able to find such a mdl function, does one exist? 
 MSElement *elP;

Hi Brenden,

 Can you share more information? Where MSElement comes from? Is it "in memory" object or it was read from DGN file?

 When you need to work with element descriptor, create it ;-) 
 I recommend to read SDK documentation (specifically Element Descriptors chapter in MicroStation Programmer Guide ), where internal structure of the descriptors is explained in detail.

 Yes, but what from available functions is the best, depends on context.

 What about e.g. mdlElmdscr_new()?
