MicroDrainage Network

It would be very useful if it was possible to change the dims of many manholes at once. It'a a very laborious and time consuming task to change each dimension one-by-one, especially if the network is very large!

Can we get a function to lock/retain MH numbers, If you have multiple dummy MH's and need to make changes any name you have given to these is lost when renumbering. You then need to go through the whole process again.

One of the aims of BIM is that all the different models you create match. If you issue a pipe network 3D model for construction with certain pipe numbering and then a minor change happens this can affect every pipe number in the system. But once it's already been issued for construction you can't afford to change pipe numbers as it would be too confusing, which means that the 3D model can no longer match the Microdrainage model.

It would be very useful if DrawNetCAD had the option of updating an existing Civil3D pipe network when using the Export to Civil3D option.
The Autodesk Microdrainage Utility has this ability, albeit it can be unreliable.
