31 — Comprehensive Workflow & Human Factors Analysis

Note

Document type: Engineering analysis Created: 2026-02-23 Method: Programmatic cross-reference of CSV Manual.pdf, 44 DCL dialogs, 126 LSP modules, and csv.mnu menu definition. Scope: Complete workflow mapping, data flow tracing, human factors evaluation, and Design FMEA for ConstructiVision v11.

1. Program Purpose Statement

ConstructiVision is a tilt-up concrete panel detailing system that runs inside AutoCAD. It automates the creation of:

  1. Panel shop drawings — 3D solid models of individual concrete wall panels with openings, blockouts, reveals, chamfers, hardware, and dimensioning

  2. Site drawings — plan-view layouts showing panel placement on building footprints with grid lines, wall lines, slab edges, and footing connections

  3. Engineering data exports — structured data files sent to lift engineering firms (Dayton/Richmond, Meadow-Burke, WSB/White Cap) for crane lift analysis and brace design

  4. Materials lists — quantity take-offs for concrete, form material, hardware, chamfer, reveal strip, and connections

  5. Panel books — batch-printed drawing sets with revision history

The program replaces manual drafting of tilt-up panel details — a process that typically takes 2–4 hours per panel by hand — with a dialog-driven parametric system that generates a fully dimensioned 3D panel in minutes.

2.2 Central Data Structure: panelvar

The entire system revolves around a single association list called panelvar. Every dialog reads from it and writes back to it. It is persisted as an XRecord in AutoCAD’s Named Object Dictionary under the key "panel_list".

panelvar = (
  ("mpvar" . (...))   ;; Panel geometry: width, height, thickness, elevations
  ("rovar" . (...))   ;; Rough openings (4 slots)
  ("wdvar" . (...))   ;; Standard openings (6 slots)
  ("drvar" . (...))   ;; Man doors (6 slots)
  ("dlvar" . (...))   ;; Dock levelers (3 slots)
  ("sbvar" . (...))   ;; Rectangular blockouts (6 slots)
  ("rbvar" . (...))   ;; Round blockouts (6 slots)
  ("fhvar" . (...))   ;; Horizontal feature strips (19 slots across 3 pages)
  ("fvvar" . (...))   ;; Vertical feature strips (19 slots across 3 pages)
  ("plvar" . (...))   ;; Pilasters (2 slots)
  ("llvar" . (...))   ;; Lintels (2 slots)
  ("tpvar" . (...))   ;; Top plate / greenplate
  ("lbvar" . (...))   ;; Ledger bar / greenplate
  ("chvar" . (...))   ;; Chamfer parameters
  ("tsvar" . (...))   ;; Top steps (2 slots)
  ("fsvar" . (...))   ;; Footing steps (2 slots)
  ("ssvar" . (...))   ;; Spandrel seats (2 slots)
  ("sdvar" . (...))   ;; Slab dowels (4 slots)
  ("bpvar" . (...))   ;; Brace points (8 slots)
  ("ppvar" . (...))   ;; Pick points (8 slots)
  ("wcvar" . (...))   ;; Weld connections (15 slots across 5 pages)
)

21 variable groups × N slots each = ~1,826 discrete input parameters.

3. Complete Workflow Maps

3.1 Master Navigation Flow

The top-level menu is labeled “ConstructiVision” and the first item is “Drawing Setup” (renamed from “Program Options” — see Section 3.1b) — a single entry point that routes to either panel editing or site editing based on the drawing’s contents.

How panel vs. site detection works:

  1. Primary method (csv.lsp): Dictionary key lookup in the AutoCAD Named Object Dictionary — checks for "panel_list" first, then "site_list". This is the real routing mechanism.

  2. User choice (csv.lsp → dwgtype.dcl): If neither dictionary entry exists, the csv_ask_dwgtype function presents the Drawing Type dialog (dwgtype.dcl) with “Panel Drawing” / “Site Drawing” / “Cancel” buttons. The user explicitly chooses.

  3. Template detection (dwgnew.lsp): When creating a new drawing from an existing template, filename patterns are tried first — *site* → site, *panel*,*pnl* → panel. If the filename is ambiguous, the same dwgtype.dcl dialog is shown.

Note

The fallback no longer silently defaults to panel mode. An unrecognized drawing will always prompt the user to choose, eliminating the risk of misrouting a site drawing to the panel editor.

3.1a progcont Routing — VLX vs Source Mismatch (Updated Mar 1, 2026)

The top-level menu items set different progcont values before calling csv;. In VLX mode, the compiled bytecode reads progcont and routes to distinct dialogs. In source-mode (.lsp), the routing code is missing — all items fall through to the same dialog.

Root cause — VLX/source mismatch (discovered Mar 1, 2026):

The CSV.VLX was compiled from source code that does not exist in this repository. Binary analysis of the VLX reveals:

  1. VLX’s embedded md_dlg.dcl = “ConstructiVision - Program Options” with numeric button keys ("2", "8", "16", "32", "64", "128", "256", "512", "1024", "2048", "4096", "16384") that map to progcont bitmasks.

  2. Source md_dlg.dcl (both PB11 and TB11 folders) = “ConstructiVision – Panel Options” with string keys ("new", "old", "val", "pal", "vgp", etc.) — a completely different, lower-level dialog for panel sub-feature selection.

  3. VLX’s compiled c:csv reads progcont and routes to different dialogs per value. The source csv.lsp never reads progcont — it uses pnl and ld variables instead.

The progcont bitmask system uses base 262144 (0x40000) = “already loaded, skip project dialog”. Button keys are powers of 2. The menu sets (setq progcont N) then calls csv;. The VLX bytecode decodes the bitmask and routes accordingly. This routing code was never committed to the source tree.

The csv.mnu file is the authoritative source for all progcont values (17 menu items with their progcont assignments). The au3 test fixture replicates exactly what the menu macros do: (progn (setq progcont N)(c:csv)).

Important

progcont is NOT dead code in VLX mode — it is the primary routing mechanism. OCR evidence from VM 102 (PB11/VLX) confirms each progcont value produces a distinct dialog. To make TB11 source-mode pass the au3 validation tests, the missing progcont routing must be reconstructed in csv.lsp and the VLX’s numeric-key md_dlg.dcl / md_dlg.lsp must be reverse-engineered or rewritten from scratch based on OCR evidence of the working dialogs.

3.1b Changes Applied

The following improvements have been implemented in this sprint:

  1. Menu renamed: “Program Options” → “Drawing Setup” — the old name implied application settings, not drawing configuration. The new name accurately describes what the user is doing: setting up or configuring a drawing within ConstructiVision.

  2. Drawing type choice dialog added: New file dwgtype.dcl with helper function csv_ask_dwgtype in csv.lsp. When the Named Object Dictionary has neither "panel_list" nor "site_list", the user is now presented with:

    • “Panel Drawing” — routes to md_dlg (Panel Options)

    • “Site Drawing” — routes to site_dlg (Site Options)

    • “Cancel” — exits without action

  3. Template detection improved in dwgnew.lsp — now tries both *site* and *panel*,*pnl* filename patterns before falling back to the same drawing type choice dialog. Previously, any non-“site” filename silently defaulted to panel mode.

3.2 Panel Creation / Editing Workflow

This is the primary workflow — ~90% of user time.

Step  Dialog/Function    User Action                        Code Path
────  ─────────────────  ─────────────────────────────────  ──────────────
 1    md_dlg             Click "New Panel" or "Edit Panel"  md_dlg.lsp
 2    mp_dlg             Enter panel #, dimensions, scale   mp_dlg.lsp
 3    [sub-dialogs]      Define panel features (see 3.3)    *_dlg.lsp
 4    OK in mp_dlg       Validates, saves panelvar          okcanhlp.lsp
 5    panel()            Writes XRecord, calls drawpan      panel.lsp
 6    drawpan()          Builds 3D solid geometry           drawpan.lsp
 7    opening()×N        Subtracts openings from solid      opening.lsp
 8    feature()×N        Adds reveal strips                 feature.lsp
 9    green()×N          Adds greenplate/ledger geometry    green.lsp
10    weldconn()         Places connection blocks           weldconn.lsp
11    chamfer()          Applies edge chamfers              chamfer.lsp
12    finpan()           Center of gravity, points, dims    finpan.lsp
13    drawdim()×5        Dimension chains per layer group   drawdim.lsp
14    TITLE/BORDER       Insert title block with attributes finpan.lsp
15    Save               Write .dwg file                    finpan.lsp

Elapsed time per panel: 3–15 minutes depending on complexity. Geometry operations: 3D Boolean (UNION/SUBTRACT) pipeline.

3.3 Panel Feature Sub-Dialog Map

5.2 Input Validation Architecture

Validation is handled by rangchck.lsp (11,498 bytes) which:

  • Validates numeric ranges for every dimensional edit_box

  • Displays warning dialog for out-of-range values

  • Clamps values to min/max bounds

  • Handles ft-in-fraction parsing (e.g., “6’-4 1/2””)

enable.lsp and fenable.lsp handle control enabling/disabling based on toggle states and snap-to-edge selections.

7. Issues & Discrepancies Found

7.1 Broken Functionality

#

Issue

Severity

Detail

BRK-01

pcAnywhere remote support

❌ Defunct

Symantec discontinued pcAnywhere in 2014. The manual documents it extensively but the feature is dead. Remove from manual and menu.

BRK-02

csv.hlp Help file

❌ Non-functional on Win10+

WinHelp (.hlp) viewer removed from Windows Vista+. Help menu item and all acad_helpdlg calls fail silently. Need CHM or HTML conversion.

BRK-03

csv.GID index

❌ Orphaned

Global index for csv.hlp — useless without WinHelp runtime.

BRK-04

progcont routing missing from source

⚠️ Source-mode broken

Every menu item sets progcont via (setq progcont N) before calling csv;. The VLX bytecode reads progcont and routes correctly (confirmed by OCR evidence from VM 102). However, no .lsp source file reads progcont — the routing code exists only in compiled VLX bytecode from uncommitted source. The source csv.lsp uses pnl/ld variables instead. In source-mode, all menu items fall through to the same md_dlg “Panel Options” dialog. See Section 3.1a for full analysis including bitmask decoding and VLX binary evidence.

BRK-05

Source md_dlg ≠ VLX md_dlg

⚠️ Missing source

The VLX’s embedded md_dlg.dcl is “Program Options” with numeric button keys (powers of 2 mapping to progcont bitmasks). The source md_dlg.dcl is “Panel Options” with string keys ("new", "old", "val", etc.) — a completely different, lower-level dialog. The VLX version is the top-level hub that routes menu items to different features. The source version is a panel sub-feature selector. The VLX was compiled from source that was never committed to the repository. Menu renamed from “Program Options” to “Drawing Setup”; progcont routing reconstruction required for source-mode.

BRK-06

Panel/site auto-detection is fragile

✅ Fixed

Drawing type was determined by dictionary lookup with no user override; fallback always defaulted to panel mode. Now: when neither "panel_list" nor "site_list" exists, dwgtype.dcl asks the user to choose. Template detection in dwgnew.lsp also improved with *panel*,*pnl* pattern and dwgtype.dcl fallback.

7.2 Naming / Documentation Discrepancies

#

Issue

Detail

DIS-01

“Roof Line” vs “Rough Opening”

Manual section “Roof Line” refers to ro_dlg which is actually “Rough Opening.” The ROofline naming exists nowhere in the code. Confusing for maintainers.

DIS-02

Manual says “Version 10.nn”

About dialog says v10.nn but TB11 files are v11. Manual was never updated for v11 release.

DIS-03

Address discrepancy

Manual lists two addresses: Mill Creek (main) and Bremerton (support). These may both be outdated.

DIS-04

“AutoCAD 2000 or higher required”

Manual says this but also references R14 compatibility. csvcompat.lsp supports back to R14 for menu loading but program itself requires AC2000+.

DIS-05

Spanish language option

Manual notes “the Spanish option does not work very well at present.” Code has language selection in project dialog but status is unclear.

DIS-06

File path references

Manual references C:\Program Files\ACAD2000\Csv\ in multiple places. csv.prj was already updated to C:\Program Files\ConstructiVision\ but the manual still has old paths.

7.3 Unclear / Undocumented Behavior

#

Issue

Detail

UNC-01

Script recursion for batch

btch.lsp creates a .scr file that opens drawings and calls back into CV functions. If a panel has errors, the entire batch stops with no recovery. No error handling in the recursion loop.

UNC-02

Encrypted .pnl import

makepan.lsp decrypts .pnl files using char-code subtraction with fixed offsets (51+n, 79+n, 81+n, 91). This is security through obscurity — the “encryption” is trivially reversible.

UNC-03

No undo for batch operations

Batch redraw/update overwrites drawings with no backup mechanism. Manual mentions “Warning message will be displayed” but there is no undo path.

UNC-04

massprop parsing

centgrav.lsp reads massprop output from a text file generated by AutoCAD’s MASSPROP command run via script. This is fragile — depends on exact text formatting of AutoCAD’s output.

UNC-05

cv.bat / cvplst.bat

csv.lsp generates batch files at runtime for directory listing and path setup. These are not documented and may trigger antivirus warnings on modern systems.

8. Human Factors Analysis

8.1 Heuristic Evaluation (Nielsen’s 10 Usability Heuristics)

#

Heuristic

Rating

Assessment

H1

Visibility of system status

⚠️ Fair

process.dcl shows “Please Wait” but no progress bar, no % complete, no panel count during batch ops.

H2

Match between system and real world

✅ Good

Uses construction industry terminology (tilt-up, pilaster, ledger, greenplate, chamfer). Domain experts will understand.

H3

User control and freedom

❌ Poor

No undo within dialogs. Cancel loses ALL changes, not just the last one. Batch operations are irreversible. Three menu items (New Project / New Drawing / Edit Existing) promise distinct actions but route to the identical dialog — user has no shortcut to the action they selected.

H4

Consistency and standards

⚠️ Fair

Consistent edit_box+slider pattern is good. But dialog layout varies — some use pages (wc: 5 pages), some use long scrolling layouts. Toggle placement inconsistent across dialogs. Menu items suggest different functions but all lead to the same place, violating the principle of least surprise.

H5

Error prevention

⚠️ Fair

rangchck.lsp validates ranges well. But no validation on cross-field dependencies (e.g., opening wider than panel triggers warning only after drawing fails).

H6

Recognition over recall

❌ Poor

Users must remember panel numbers (3 digits), feature slot numbers, and coordinate conventions. No visual preview of panel during editing.

H7

Flexibility and efficiency

✅ Good

Template system (copy panel), batch operations, slider+editbox dual entry. Power users can work fast.

H8

Aesthetic and minimalist design

❌ Poor

DCL dialogs are dense, cluttered. wc_dlg has 615 controls across 5 pages. Wall_dlg has 711 controls across 4 pages. Information overload.

H9

Help users recognize/recover from errors

⚠️ Fair

Warning dialogs exist but error messages are terse. No suggestion of how to fix. No contextual help in dialogs.

H10

Help and documentation

❌ Broken

csv.hlp (WinHelp) non-functional on Win10+. Context help buttons call dead links. Manual is PDF-only (now also .md).

3

72

Document that edit_box is authoritative, slider is approximate

13

progcont routing missing from source

Menu sets variable that only VLX reads

In source-mode: all menu items route to same dialog (“Panel Options”). In VLX mode: works correctly — each progcont value produces a distinct dialog. VLX compiled from uncommitted source; source md_dlg.dcl is wrong dialog.

8

VLX compiled from uncommitted source; routing code + numeric-key md_dlg never checked into repo

10

VLX mode works; source-mode completely broken

3

240

Reconstruct progcont routing in csv.lsp; reverse-engineer numeric-key md_dlg from OCR evidence of working VLX dialogs

18

Panel/site auto-detection

Drawing misidentified as panel or site

Panel editor opens for site drawing (or vice versa); user cannot do site operations on misrouted drawing

7

Dictionary lookup with no user override; new-from-template uses crude filename match *site*

3

User aware of commit-per-dialog behavior

6

126

Implement transaction: buffer changes until top-level OK

16

Spanish language option

17

btch_dlg panel selection

“Select All” selects damaged/incomplete panels

Batch processes panels that will fail

5

No validation of panel health before batch start

4

Individual panel errors may crash batch

7

140

Pre-validate panel data before batch processing; report unloadable panels

19

AutoCAD profile/registry

Menu registration missing from profile

CV menu not visible; csv; command fails with “setvars Function cancelled” when menu-dependent code paths execute

8

Profile migration, registry corruption, incomplete install, or VM cloning without full config

3

None — silent failure until menu item invoked

7

168

Add menu registration check to Configure-ConstructiVision.ps1; validate on startup; add recovery path

20

Startup Suite / VLX loading

VLX crash during Startup Suite load

AutoCAD crashes with 0xC0000005 at LocalizeReservedPlotStyleStrings+533; CSV command unknown

9

Startup Suite loads VLX before printer/plot subsystem is fully initialized; incomplete installation environment

3

None — crashes silently on startup

8

216

Defer VLX loading via acaddoc.lsp; investigate printer/plot config dependency; add to deployment script

21

Project Settings / registry

Project path not registered

7

Manual/incomplete installation skips registry key creation for Project Settings\CV\RefSearchPath

3

None — user must navigate manually

6

126

Add RefSearchPath registration to Configure-ConstructiVision.ps1; validate project paths on startup

DFMEA Summary

RPN Range

Count

Action Level

300–500

3

Immediate — redesign required (Help system, weld connections, dimensional entry)

200–299

5

High — design improvement recommended (batch error handling, Boolean validation, feature toggles, VLX crash, progcont routing)

100–199

7

Medium — improvement desired (centgrav parsing, materials, .bat generation, panel selection, XRecord, panel/site detection, project paths)

<100

4

Low — monitor or document (convert, slider, encryption, translation)

Top 3 risks by RPN:

  1. RPN 500 — csv.hlp Help system — completely non-functional, affects all users

  2. RPN 360 — Weld connection data entry — cognitive overload + safety-critical output

  3. RPN 315 — Dimensional data entry — high error probability with no visual preview
