I want to know how to use codes to open AccuDraw

There is an AccuDraw example delivered with the MicroStation CONNECT SDK...

Development language is MDL

The MicroStation CONNECT SDK provides the MicroStationAPI C++ interface.  While some MDL functions remain, the API is mostly C++ classes.

For example, if you search MicroStationAPI help you will find classes for both AccuDraw and AccuSnap.

Thank you,and please to know you ,indeed.

Development of language is MDL ,Microstation type is CE, I want to know how to use codes to open AccuDraw during a draw line operate

Hi George,

please read and follow MicroStation Programming forum best practices. Without information mentioned there it's hard to provide an answer:

• What MicroStation do you use? Please state exact build number (e.g. to only mention V8i is not enough in many cases).
• What language do you use? From mentioned DgnPrimitiveTool we can deduce it's probably C++, but you only know it for sure.
• Don't ask more different questions in one post!

With regards,

 Jan
