PDF floor plan

The classic plan excerpt: set the scale against a known distance, walls and rooms are read automatically.

DWG / DXFCAD

CAD drawing

AutoCAD® plans come in true to scale – and go back congruently: devices as blocks with attributes, rooms as polylines, and changes made in CAD are reconciled.

BIM model

The model brings floors, rooms and heights along — no calibration needed. Detectors go back into coordination as BCF.

Floors & roomsRoom heightsBCF back
AUTOCAD® ROUND TRIP

Back to AutoCAD® – congruent, as blocks, with a way back

Your design lands in the coordinate system of the original DWG. Every device is a block with attributes, every room a polyline – and whatever you move in CAD comes back.

  • 1:1 in the original coordinates

    INSERT at 0,0 with scale 1 – no scaling, no moving, no unit conversion.

  • Blocks with attributes

    One block per VdS 2135 symbol with designation, group, type, room, storey and status – ready for DATAEXTRACTION.

  • Changes come back

    Load the edited DXF/DWG again: moved, deleted and new devices are reconciled before anything is saved.

Drawing symbols after VdS 2135, created by PlanWerke – not an official VdS document. The DXF file (AC1021) opens in AutoCAD® 2007 and later, BricsCAD and other DWG-compatible CAD applications.

Wissens-Bereich: 21 neue Fach-Artikel – jetzt 31 Artikel zu BMA, Rauchwarnmeldern, SAA und EMA

Das Planungswissen unter /wissen/artikel wächst von zehn auf 31 frei zugängliche Artikel.

NEW
Prüf-Reiter: TAB-Abweichungen auch für Blitzleuchte, FSD und Laufkarten – mit neuen Projektangaben

Der Planungsumfang der BMA hat einen neuen Abschnitt „Einrichtungen für die Feuerwehr und Laufkarten“ – im Workflow der Projektansicht und im Planungsumfang-Dialog des Viewers: Farbe der Blitzleuchte (Rot, Gelb, Orange, Grün, Bernstein, Blau, Klar/Weiß), Typ des Feuerwehr-Schlüsseldepots (FSD 1–3), Format der Feuerwehr-Laufkarten (DIN A3/A4) und die Zahl der Ausfertigungen je Satz.

NEW
Feuerwehr-Laufkarten: Einsatzweg in der Flurmitte, Wege über Geschosse mit Schnitt, A3-Ausgabe und Bereiche im Detailplan

Der grüne Einsatzweg der Feuerwehr-Laufkarten wird jetzt echt trassiert: In Fluren folgt er der Flurmitte (dem Flur-Skelett, das auch die Melder-Abstandsregel nutzt), in Räumen dem begehbaren Weg um Ecken, und Verkehrswege werden bevorzugt – der Weg durch zwei Büros ist nicht mehr der Einsatzweg, wenn der Flur daneben liegt.

NEW
KI-Copilot im Viewer: Räume erkennen, Geräte automatisch platzieren und Exporte per Chat – Verlauf auf Wunsch speichern

Der KI-Workflow-Copilot (KI-Copilot-Tarif) ist jetzt auch direkt im Viewer erreichbar – über den Knopf „Copilot“ in der Werkzeugleiste oder die Befehlspalette (⌘K → „KI-Copilot öffnen“).

Briefly asked

Yes. Upload the plan, calibrate the scale against a known distance — walls and rooms are detected automatically, even on scans without vector geometry. An IFC model is optional.
