Such as "API_MeshType" in v11,when I attampt to create it using "ACAPI_Element_Creat",I don't know what are the input parameters to set before creating.How do I?
A detailed answer would be too long. Basically you need to fill in the structure for the type of element you want to create, e.g. if you want to create a line you need to fill in the 'API_LineType' structure of the union called 'API_Element'.
The easiest way is to first use 'ACAPI_Element_GetDefaults', which fills in all the default settings for the element. You can then set the values of specific fields as required before calling 'ACAPI_Element_Create'.
Take a look at the 'Element_Test' example bundled with the API dev kit too.
