[VBA v8i SS4] Implementing ptopo modify in PowerView

dalmar

Hi,

we are using Bentley Map PowerView. We wanna develop our own VBA tool that will be run inside PowerView but would have some

functionalities of Map Standalone's persistent topology (modify, split, merge) and additional functionalities related to our

project. All levels in file would be part of topology. Any idea how to implement ptopo mofify command?

 

There must be other solution than:

- starting iprimitive commands

- finding parcels at selected boundary data point

- starting dynamics for displaying modifications

- Finding elements within parcels during dynamics and displaying their modifications

This could be very slow.

    Hi dalmar,

    in my opinion there are two distinct levels here: legal and technical.

    Legal: I don't remember it well, but I guess it can be in a conflict with License Agreement. On the other hand I understand your intention is to develop project-specific in-house tool, not to create and sell application that will add Map Standalone functionality to Map PowerView, so it's probably not huge issue.

    Technical: I don't know ptopo modify command functionality in detail, but the topology functionality implementation is seriously complex topic. Plus it has to be adapted to used XFM model. So in my opinion VBA is for sure not right tool for such task ... or at least there is a threat VBA API will not provide enough functionality or enough performance.

    It's not clear how your topology modification will be complex and how it shoudl work, so it's not possible to do any particular advice than "try something".

    My question is: What do you mean by "There must be other solution than..."? What you described is the right solution. And based on what you suppose other solution exists?

    With regards,
