Command:
Main command
• MHPipes2SurfacesProfilesElevationTool – opens the manhole elevation adjustment dialog and runs the tool.
• MHPipes2SurfacesProfilesElevationTool – opens the manhole elevation adjustment dialog and runs the tool.
Description:
What this program does
• Scans the drawing and lists all available TIN surfaces and profiles in the dialog, each with a checkbox for activation.
• Allows the user to select manholes in Model space and manholes in Profile view; these are shown in separate lists and can be toggled individually.
• For each checked manhole, tries to obtain elevation from the selected profiles first and, if that fails, from the selected TIN surfaces at the manhole XY position.
• Applies a user defined surface elevation offset or profile elevation offset before setting the final rim elevation.
• Writes the computed elevation back to the structure RimElevation property and updates the Z of its Position point to keep graphics consistent.

Helper function: (if any)
Important helper logic
• MH-AddStructuresFromDrawing reads the selection set and adds AeccDbStructure objects from plan, plus structures mapped from AeccDbGraphProfileNetworkPart entities in profile views.
• MH-SelectSurfacesFromDrawing lets the user pick TIN surfaces on screen and automatically checks their entries in the Surfaces list.
• MH-SelectProfilesFromDrawing lets the user pick profiles in profile views and auto checks the matching profile entries.
• MH-SetStructureElevToSources computes a single elevation value for each manhole, using the selected profiles or surfaces plus the chosen offsets and writes it back to the object.
• MH-ApplyCurrent processes all checked manholes in one pass and calls REGEN so the new elevations are visible immediately.
• MH-AddStructuresFromDrawing reads the selection set and adds AeccDbStructure objects from plan, plus structures mapped from AeccDbGraphProfileNetworkPart entities in profile views.
• MH-SelectSurfacesFromDrawing lets the user pick TIN surfaces on screen and automatically checks their entries in the Surfaces list.
• MH-SelectProfilesFromDrawing lets the user pick profiles in profile views and auto checks the matching profile entries.
• MH-SetStructureElevToSources computes a single elevation value for each manhole, using the selected profiles or surfaces plus the chosen offsets and writes it back to the object.

Functionalities:
Functionalities
Surface selection area
• Shows all TIN surfaces in a grouped list with checkboxes, initially all off.
• A Select Surfaces button lets the user pick one or more surfaces from the drawing and automatically checks them in the list.
• Select All and Select None buttons quickly toggle all surface checkboxes.
Profile selection area
• Lists all profiles associated with alignments in the drawing with their display names.
• A Select Profiles button allows graphical selection of profiles and auto checks them in the dialog.
• Select All and Select None manage the entire profile list at once.
Manholes (Model space)
• Shows each selected AeccDbStructure from plan as “DisplayName – PartSizeName”, one item per row with a checkbox.
• Buttons Model: All and Model: None select or deselect all model manholes in a single click.
Manholes (Profile view)
• Shows manholes that were selected through profile view network graphics and mapped back to their model structures.
• Buttons Profile: All and Profile: None control the entire profile based manhole list.
Select Manholes button
• A wide button spanning below both manhole columns that allows repeated selection of manholes in both plan and profile views without closing the dialog.
Elevation offset controls
• One numeric field for the Surface elevation offset, which is added to surface based elevations.
• One numeric field for the Profile elevation offset, which is added to profile based elevations.
Source priority
• For each manhole, the routine first projects its XY onto the alignment of every checked profile and tries to evaluate the profile elevation at that station.
• If no valid profile elevation is found, the routine queries each checked TIN surface at the same XY until one returns a valid height.
Control buttons
• Apply updates all checked manholes using the current settings and regenerates the drawing but keeps the dialog open for further edits.
• OK performs the same update then closes the dialog.
• Cancel exits the dialog without changing anything further.

Result:
Result
• All selected manholes are set to rim elevations derived from the chosen profiles or TIN surfaces plus the corresponding offsets.
• Manholes picked from profile views are safely mapped back to the underlying model structures so there is no duplication or mismatch.
• The designer can iterate quickly using the Apply button until all manhole elevations match the intended design before committing with OK or abandoning with Cancel.
