Promoting an element

All,

I am new to GC so please pardon my ignorance.

I have a surface created from survey data in a dgn file. This file has too many points that form a mesh. I am trying to attach this surface as reference in a new file and then merge it to the master. Then, promote the mesh element so that I can get a list of Dpoint3Ds which would be lightweight. The original points make the application too slow and less easy to work with.

Do you have any suggestions to make working with this surface easier? I need all available points though.

I am attaching the dgn file with the surface for reference.

Your help is very much appreciated.

Thanks,

Sathya
