Please provide a sample code or the model you generated. Otherwise we can't really help you to debug the issue.

Show ToolTip to each geometry added in VIewPort3Dx

Do hit test, get the hitted geometry hit point. Project hit point onto screen space using viewport.project. create a tooltip yourself.
