Annahmen (Assumptions) + +1. **Primär Desktop:** Die Anwendung wird primär auf Desktop-Geräten (≥1280px Breite) verwendet; mobile Unterstützung ist nicht Teil der initialen Version. +2. **Deutsche UI:** Die Benutzeroberfläche wird primär auf Deutsch entwickelt; Mehrsprachigkeit kann später hinzugefügt werden. +3. **Keine 3D:** Die Anwendung ist rein 2D; keine 3D-Modellierung oder 3D-Ansicht. +4. **DXF als primäres Austauschformat:** DXF ist das wichtigste Import/Export-Format für CAD-Interoperabilität; DWG ist optional und von Open-Source-Library-Verfügbarkeit abhängig. +5. **CRDT als Synchronisations-Standard:** CRDT (Yjs) wird als Standard für Echtzeit-Kollaboration angenommen; OT wird nicht verwendet. +6. **Canvas 2D als primärer Renderer:** Canvas 2D mit räumlichem Index (rbush) wird als primäre Rendering-Technologie angenommen; WebGL ist optional. +7. **Einzelner Server-Deployment:** Initiales Deployment ist ein einzelner Server (Docker/Coolify); horizontale Skalierung ist später möglich. +8. **SVG-Import als Bibliothekserweiterung:** SVG-Dateien werden primär für die Bibliothek importiert; SVG als Projekt-Import ist sekundär. +9. **Open Source:** Alle Komponenten sind Open Source; web-cad selbst wird als Open Source lizenziert (AGPL-3.0 oder MIT). +10. **Bestuhlungs-Stühle als Bibliothek-Blöcke:** Stühle für Bestuhlungs-Tools werden als Blöcke in der Bibliothek definiert, nicht fest codiert. +11. **E-Mail/Passwort-Auth:** E-Mail/Passwort ist die Authentifizierungsmethode; keine OAuth2/SSO in der initialen Version. +12. **Universelle Erweiterbarkeit:** Die Plugin-Architektur ist so konzipiert, dass die Software später in jede Richtung erweiterbar ist (neue Branchen, Formate, UI-Komponenten). +13. **SQLite als Standard-Datenbank:** SQLite wird als Standard-Datenbank verwendet; Datenbank-Schicht ist abstrahiert für spätere Migration zu PostgreSQL/MySQL. +14. **API-First-Design:** Die Software ist API-first designed; das Backend ist ein API-Server, die UI ist ein API-Client. Dadurch ist die Software an andere Systeme anhängbar. +15. **KI Copilot als Kern-Feature:** Der KI Copilot ist von Anfang an in die Core-Architektur integriert – kein Afterthought. CAD-Operationen sind als Functions registriert, die vom LLM aufgerufen werden können. +16. **OpenAI-kompatibler KI-Endpoint:** KI wird über einen OpenAI-kompatiblen API-Endpoint angebunden (user-provided); kein lokales Modell-Deployment. User bringt eigenen Endpoint mit (OpenAI, OpenRouter, Ollama OpenAI-Compat, vLLM OpenAI-Compat, etc.). +17. **Function Calling als KI-Pattern:** Das LLM verwendet Function Calling / Tool Use, um CAD-Operationen auszulösen. Das LLM generiert keine direkten Canvas-Befehle, sondern ruft registrierte Functions auf. +18. **Modularität:** Core, Plugins, KI-Backend und UI sind lose gekoppelte Module mit definierten Schnittstellen. + +--- + +## 6. Non-Goals (Nicht im Scope der initialen Version) + +1. **Keine 3D-Modellierung** – rein 2D; keine 3D-Ansicht, keine Höhen, keine 3D-Renderings. +2. **Keine mobile App oder mobile-optimierte UI** – Desktop first; mobile wird erst bei Bedarf addressed. +3. **Keine lokalen Druck-/Plot-Konfigurationen** – PDF-Export ersetzt direktes Drucken in der ersten Version. +4. **Keine AutoCAD-LISP-/Macro-Skripting-Engine** – keine benutzerdefinierten Skripte in LISP/AutoLISP. +5. **Keine parametrische Modellierung** – keine Constraint-basierte Geometrie oder parametrischen Relationen. +6. **Keine BIM-Integration** – keine IFC-Importe, keine BIM-Datenmodellierung. +7. **Keine Desktop-Installation** – rein web-basiert; keine Electron-/NW.js-Desktop-App. +8. **Keine Multi-Tenant-Isolierung auf Organisationsebene** – initiale Version ist Single-Tenant; Multi-Tenant später. +9. **Keine erweiterten Druck-Layouts** – keine Plot-Styles, Linienstärken-Tabellen oder Print-Studio-Konfigurationen. +10. **Keine Video-/Audio-Kommunikation** – keine integrierte Video- oder Audio-Calls zwischen Nutzern. +11. **Keine automatische Flächenberechnung / Mengenermittlung** – in der ersten Version nicht enthalten. +12. **Kein OAuth2/OIDC/SSO** – E-Mail/Passwort reicht; SSO kann später als Plugin nachgerüstet werden. +13. **Keine AutoCAD-Block-Editor-Äquivalenz** – Block-Definitionen können bearbeitet werden, aber kein vollständiger Block-Editor wie in Desktop-AutoCAD. +14. **Keine CAD-Standards-Verwaltung** – keine DWS-Dateien oder Standards-Checking wie in Desktop-AutoCAD. +15. **Keine 3D-Viewing** – anders als AutoCAD Web (das DWG-3D-Viewing bietet), ist web-cad rein 2D. +16. **Keine autonomes KI-Zeichnen** – der KI Copilot führt Befehle auf Anweisung aus, aber zeichnet nicht selbstständig komplexe Zeichnungen ohne User-Anweisung. Autonomes Zeichnen ist ein späteres Feature. +17. **Keine KI-Training/Fine-Tuning** – die initialen KI-Modelle werden nicht fine-getuned; Standard-Modelle mit Function Calling werden verwendet. + +--- + +## 7.

Annahmen (Assumptions) + +1. **Primär Desktop:** Die Anwendung wird primär auf Desktop-Geräten (≥1280px Breite) verwendet; mobile Unterstützung ist nicht Teil der initialen Version. +2. **Deutsche UI:** Die Benutzeroberfläche wird primär auf Deutsch entwickelt; Mehrsprachigkeit kann später hinzugefügt werden. +3. **Keine 3D:** Die Anwendung ist rein 2D; keine 3D-Modellierung oder 3D-Ansicht. +4. **DXF als primäres Austauschformat:** DXF ist das wichtigste Import/Export-Format für CAD-Interoperabilität; DWG ist optional und von Open-Source-Library-Verfügbarkeit abhängig. +5. **CRDT als Synchronisations-Standard:** CRDT (Yjs) wird als Standard für Echtzeit-Kollaboration angenommen; OT wird nicht verwendet. +6. **Canvas 2D als primärer Renderer:** Canvas 2D mit räumlichem Index (rbush) wird als primäre Rendering-Technologie angenommen; WebGL ist optional. +7. **Einzelner Server-Deployment:** Initiales Deployment ist ein einzelner Server (Docker/Coolify); horizontale Skalierung ist später möglich. +8. **SVG-Import als Bibliothekserweiterung:** SVG-Dateien werden primär für die Bibliothek importiert; SVG als Projekt-Import ist sekundär. +9. **Open Source:** Alle Komponenten sind Open Source; web-cad selbst wird als Open Source lizenziert (AGPL-3.0 oder MIT). +10. **Bestuhlungs-Stühle als Bibliothek-Blöcke:** Stühle für Bestuhlungs-Tools werden als Blöcke in der Bibliothek definiert, nicht fest codiert. +11. **E-Mail/Passwort-Auth:** E-Mail/Passwort ist die Authentifizierungsmethode; keine OAuth2/SSO in der initialen Version. +12. **Universelle Erweiterbarkeit:** Die Plugin-Architektur ist so konzipiert, dass die Software später in jede Richtung erweiterbar ist (neue Branchen, Formate, UI-Komponenten). +13. **SQLite als Standard-Datenbank:** SQLite wird als Standard-Datenbank verwendet; Datenbank-Schicht ist abstrahiert für spätere Migration zu PostgreSQL/MySQL. +14. **API-First-Design:** Die Software ist API-first designed; das Backend ist ein API-Server, die UI ist ein API-Client. Dadurch ist die Software an andere Systeme anhängbar. +15. **KI Copilot als Kern-Feature:** Der KI Copilot ist von Anfang an in die Core-Architektur integriert – kein Afterthought. CAD-Operationen sind als Functions registriert, die vom LLM aufgerufen werden können. +16. **OpenAI-kompatibler KI-Endpoint:** KI wird über einen OpenAI-kompatiblen API-Endpoint angebunden (user-provided); kein lokales Modell-Deployment. User bringt eigenen Endpoint mit (OpenAI, OpenRouter, Ollama OpenAI-Compat, vLLM OpenAI-Compat, etc.). +17. **Function Calling als KI-Pattern:** Das LLM verwendet Function Calling / Tool Use, um CAD-Operationen auszulösen. Das LLM generiert keine direkten Canvas-Befehle, sondern ruft registrierte Functions auf. +18. **Modularität:** Core, Plugins, KI-Backend und UI sind lose gekoppelte Module mit definierten Schnittstellen. + +--- + +## 6. Non-Goals (Nicht im Scope der initialen Version) + +1. **Keine 3D-Modellierung** – rein 2D; keine 3D-Ansicht, keine Höhen, keine 3D-Renderings. +2. **Keine mobile App oder mobile-optimierte UI** – Desktop first; mobile wird erst bei Bedarf addressed. +3. **Keine lokalen Druck-/Plot-Konfigurationen** – PDF-Export ersetzt direktes Drucken in der ersten Version. +4. **Keine AutoCAD-LISP-/Macro-Skripting-Engine** – keine benutzerdefinierten Skripte in LISP/AutoLISP. +5. **Keine parametrische Modellierung** – keine Constraint-basierte Geometrie oder parametrischen Relationen. +6. **Keine BIM-Integration** – keine IFC-Importe, keine BIM-Datenmodellierung. +7. **Keine Desktop-Installation** – rein web-basiert; keine Electron-/NW.js-Desktop-App. +8. **Keine Multi-Tenant-Isolierung auf Organisationsebene** – initiale Version ist Single-Tenant; Multi-Tenant später. +9. **Keine erweiterten Druck-Layouts** – keine Plot-Styles, Linienstärken-Tabellen oder Print-Studio-Konfigurationen. +10. **Keine Video-/Audio-Kommunikation** – keine integrierte Video- oder Audio-Calls zwischen Nutzern. +11. **Keine automatische Flächenberechnung / Mengenermittlung** – in der ersten Version nicht enthalten. +12. **Kein OAuth2/OIDC/SSO** – E-Mail/Passwort reicht; SSO kann später als Plugin nachgerüstet werden. +13. **Keine AutoCAD-Block-Editor-Äquivalenz** – Block-Definitionen können bearbeitet werden, aber kein vollständiger Block-Editor wie in Desktop-AutoCAD. +14. **Keine CAD-Standards-Verwaltung** – keine DWS-Dateien oder Standards-Checking wie in Desktop-AutoCAD. +15. **Keine 3D-Viewing** – anders als AutoCAD Web (das DWG-3D-Viewing bietet), ist web-cad rein 2D. +16. **Keine autonomes KI-Zeichnen** – der KI Copilot führt Befehle auf Anweisung aus, aber zeichnet nicht selbstständig komplexe Zeichnungen ohne User-Anweisung. Autonomes Zeichnen ist ein späteres Feature. +17. **Keine KI-Training/Fine-Tuning** – die initialen KI-Modelle werden nicht fine-getuned; Standard-Modelle mit Function Calling werden verwendet. + +--- + +## 7. Entschiedene Fragen (Resolved) + +| # | Frage | Antwort | Entscheidung | +|---|---|---|---| +| Q-01 | Soll die Anwendung Open Source oder Closed Source sein? Welche Lizenz? | Open Source | ✅ **Entschieden:** Software wird als Open Source lizenziert (AGPL-3.0 empfohlen für Copyleft-Schutz, MIT als Alternative).
