[quote user="Leung Harry"]I want to write a VBA code to create the point in different level[/quote]
Decide how you want to represent a point. It could be one of these...
- A zero-length line
- A point cell
- Some other graphic element
Refer to the VBA help documentation. It has plenty of examples. The way to create an element with MicroStation VBA is one of the CreateXxx methods.
