In the recent past, we had received some queries around refreshing the sections directly using the API (without having to use SendCommand).
There isn’t any direct API which allows API users to the refresh on the sections/elevations. Sending the command using SendCommand would be one workaround for some API users. But if SendCommand is not an option (as in this case), the ACA 2013 .NET API provides a method called GenerateSection which can help generate 2D sections programmatically. The method signature is included below -
Autodesk.Aec.ApplicationServices.Utility.SectionUtilities.GenerateSection(Autodesk.AutoCAD.DatabaseServices.ObjectId, Autodesk.AutoCAD.Runtime.RXClass, string, string, bool, string)
This API might help re-create sections and this might be closest to what we can do as work-around for now.
