Re: Select all elements with handles Microstation V8i

Daniel Christopher:

i want to 2D(active z value must assign to the vertex not elements z value) snap the vertex

It's not exactly clear what you want to do.  But a user can snap only to a vertex, not some arbitrary point that happens to have the same XY coordinates as a vertex but a different Z value.

You must let the user snap to what she can snap to.  After you have captured that snap point you can adjust the Z value in your code.
