    Catchment areas are worthless

    Why in world would I want a feature that I can not edit.

     

    Only way to edit is to explode (twice) to get it back to polylines and then convert back to Catchment area.

     

    Get what happens when you explode catchment areas - NOT ALWAYS - but they generally cause errors. = CRASH

     

    Would love to talk to the person that came up with this idea.

    Catchments are a function of the surface to which you created it.  If you wish to edit, the Catchment area command creates a polyline using the same calculations the catchment object uses.  Edit, and then convert to an object.

     

    If you wish to explode an object, type explode first, then select the catchment.

    You edit the object prior to converting it to a catchment.

    But after you create the catchment, in the "real engineering world" things happen, I need to move a structure and then the catchment needs to be updated. Therefore you either delete and start over or explode twice and get back to a polyline and then recreate the catchment. As I said before, exploding catchment areas will causes drawing errors from time to time.

     

    Catchment areas should be able to be edited just like feature lines

    Matt:

     

    How do you edit a catchment made from an object after the catchment is created?

     

    Are you stating this is not an option?

     

    I've never had a project without revisions...

    You can not edit. That is my whole problem with catchments.
