Typical Plan Drafting Workflow

Purpose

This note summarises the manual-defined plan drafting workflow for HAPI scripts. It explains how Series A, B, and C scripts work together to import survey data, rectify plotted results, enhance drafting clarity, and finalise plan production.

Workflow Stages

Stage	Manual Intent	Main Scripts
Import of Survey Data	Choose an appropriate import or migration route according to the source data. Proper Point_Code syntax is essential for accurate results.	A1a_Plot_Survey_Data_From_Point_Data_File, A1b_Plot_Survey_Data_From_Drawing_Selection, A4_Migrate_Survey_Data_From_Legacy_Drawing
Rectification of Plotted Symbols	Review symbol output, verify orientation and dimensions, and re-plot selected symbols when the Point Code has been corrected.	A1a_Plot_Survey_Data_From_Point_Data_File, A1b_Plot_Survey_Data_From_Drawing_Selection
Rectification of Plotted Lineworks	Review Feature Lines, correct sequencing, join fragmented segments, and use Civil 3D Feature Line editing tools rather than ordinary AutoCAD editing commands.	A1b_Plot_Survey_Data_From_Drawing_Selection
Drafting Enhancements	Improve drawing legibility through spot text management and topographic pattern generation.	B1_Spot_Text_Display_Manager, B3_Topographic_Pattern
Plan Production	Move from model-space drafting to layout production, then generate grid references and legends.	C1_Grid_Reference, C2_Drawing_Legends

Key Manual Principles

Point files and existing entities can follow a relatively direct import workflow.
DGN or DWG files created from other drafting tools require additional data exchange and quality-control procedures.
Symbol annotation may be governed internally by the block reference or by Civil 3D labels.
Linework generated by HAPI is generally represented as Feature Lines.
Feature Line edits should use Civil 3D Feature Line tools, such as break or trim.
Final plan production occurs after model-space elements are reviewed and finalised.

Relationship to Script Notes

This workflow note provides the operational context for:

Reverse-Engineering Notes

When reverse-engineering the plan drafting scripts, preserve the distinction between:

import / migration scripts;
rectification scripts;
drafting aid scripts;
layout production scripts.

Do not collapse these into one generic plotting workflow. The manual separates them for operational clarity.
