Functionalities • Surface selection area – Displays all TIN surfaces with checkboxes, initially unchecked. – Select Surfaces button lets the user pick surfaces in the drawing and auto checks their entries. – Select All and Select None toggle all surface checkboxes at once. • Profile selection area – Lists all profiles found under alignments with checkboxes, initially unchecked. – Select Profiles button allows picking profiles from profile views and auto checks them. – Select All and Select None for profiles. • Manholes (Model space) list – Shows each selected AeccDbStructure from plan view as “DisplayName – PartSizeName” one below another. – Checkboxes control which model manholes are active for elevation adjustment. – Model: All and Model: None buttons select or deselect all model manholes. • Manholes (Profile view) list – Shows manholes that were selected through profile view network graphics and mapped back to their model structures. – Checkboxes control which of these profile based manholes are processed. – Profile: All and Profile: None select or deselect all profile view manholes. • Select Manholes button – Wide button that spans beneath both manhole columns and allows repeated selection of structures from plan and profile views. • Elevation offset controls – Edit box for Surface elevation offset applied when elevations come from TIN surfaces. – Edit box for Profile elevation offset applied when elevations come from profiles. • Source priority – For every manhole the routine first projects its XY to each checked alignment and tries to get profile elevation at that station. – If no valid profile elevation is found, the routine queries each checked surface for elevation at the same XY until one returns a valid value. • Control buttons – Apply adjusts all checked manholes using current selections and offsets, regenerates the drawing and keeps the dialog open. – OK performs the same adjustment then closes the dialog. – Cancel closes the dialog without running another adjustment.
