Core platform

CAD, Drawing & Asset Mapping

Massive CAD files made fast, web-friendly, and interactive.

Overview

IDN CAFM transforms heavy CAD and BIM files into fast, browsable floor plans that anyone on your team can use.

Key capabilities

Seamlessly handle enormous Revit and CAD files without performance hits.
Use any CAD editor — AutoCAD LT, DraftSight, or your existing IWMS exports.
Instantly import polylines, including from Archibus deployments.
Dual-view mapping: CAD site plans and satellite imagery side-by-side.
Manage parking, landscape, and outside surface cover from the map.
Drop external asset symbols on plans to create a live equipment inventory.

What is the IDN CAD Drawing Engine?

The IDN CAD Drawing Engine is the 24-utility drawing toolset inside CAD, Drawing & Asset Mapping. It compares floor plan revisions, audits polylines, blocks and layers, aligns stacked floors, publishes high-resolution interactive plans, and validates every upload so square footage, room IDs and space records stay accurate.

Complete feature index

Every feature in the IDN CAD Drawing Engine, with its function and CAFM impact
Toolset	Feature	What it does	CAFM impact
Revision Control	Floor Plan Compare Slider	Compare revisions side-by-side with an interactive slider that highlights spatial adjustments.	Eliminates manual overlaying of paper prints or PDF drawing comparisons, and gives facility managers a defensible visual record of what changed between revisions.
Revision Control	Document Revision Timeline	A comprehensive history log tracking every floor plan revision since inception.	Creates an audit trail for building envelope changes, boundary shifts and square footage adjustments that stands up to external review.
Revision Control	Annex & Mapping Error Correction	Visual mapping tools to correct mistakenly included properties and annexes.	Prevents inflated tax valuations, over-allocated utility costs and incorrect lease areas caused by property mapping errors.
Revision Control	Multi-Level Spatial Auditing	Differentiate second-level exit doors, stairwells and open-to-below voids.	Ensures open vertical voids are excluded from interior square footage calculations, so stacked building totals reconcile with measured area.
Revision Control	Reverse Posting & Versioning	Roll a posted drawing back to a previous stable configuration.	Maintains business continuity when a newly posted construction draft turns out to be inaccurate.
CAD Prep & Cleanup	Polyline Audit Utility	Scan for duplicate and overlapping geometry and closed boundaries missing space IDs.	Prevents double-counted square footage and rooms left unmapped in the space database.
CAD Prep & Cleanup	Drawing Impact Analysis	Detect massive AutoCAD blocks and bloated or unnecessary layers driving file size.	Prevents slow page loads, crashes and sluggish panning in CAFM mobile and web applications.
CAD Prep & Cleanup	Block Interpretation Audit	Flag poorly interpreted blocks, such as un-exploded blocks rendering as blank rectangles.	Ensures door swings, stairwells and architectural assets are represented accurately on the published plan.
CAD Prep & Cleanup	Text ID Adjustment Tools	Batch resize Text IDs and reposition labels for maximum legibility.	Ensures room numbers are clearly visible on colour-coded web dashboards without overlapping lines.
Layer & Alignment	Vertical Alignment Extents Layer	A dedicated extents layer that aligns stacked multi-floor layouts precisely.	Ensures vertical risers, elevators, columns and structural boundaries align precisely across floors.
Layer & Alignment	Layer Set Importer	Import standard layer structures and predefined layer sets from external facility systems.	Reduces drawing onboarding time from days to minutes when migrating from legacy FM tools.
Interactive Assets	Drag-and-Drop Intelligent Symbols	Drop physical assets such as furniture and mechanical equipment directly onto live plans.	Bridges physical drawings with interactive, traceable asset databases.
Interactive Assets	Evacuation Auto-Routing	Calculate and auto-draw visual emergency evacuation paths directly on the plan.	Supports compliance with life-safety requirements and saves hundreds of hours of manual drafting.
Interactive Assets	Bulk Space Selection	Select multiple spaces simultaneously to modify properties or occupant seats.	Saves significant administrative time during large-scale department moves and reallocations.
Interactive Assets	Customizable Legend Controls	Legend creation tools with full visual theme and colour controls.	Allows customised colour coding of space types, such as workstations versus conference rooms, for each audience.
Database Integration	High-Res Visual Tile Generator	Direct-to-platform CAD upload that generates high-resolution tiles for the web interface.	Provides responsive pan and zoom for users without expensive CAD software, on web and mobile.
Database Integration	Level 1 Linking & Floors Scale Audit	Measure gross area via the Floors template and run a scale sanity check.	Acts as a firewall preventing unit and scale errors from polluting the space database.
Database Integration	Colour-Coded Audit States	Legend colour coding: grey for a perfect match, purple for recalculated spaces.	Allows rapid visual confirmation of boundary line changes and updated space areas.
Database Integration	Unidentified Space Flag	Flag closed polylines on the space layer with no room text identifier.	Alerts the technician to undesignated shafts, mechanical voids and overlooked rooms before they vanish from the inventory.
Database Integration	Upload Firewall: Duplicate Key Error	Block uploads when multiple polylines share the same room Text ID.	Prevents database conflicts where two rooms attempt to map to a single primary key.
Database Integration	Room Split Record Provisioning	Detect split polylines with new text IDs and automatically provision new database records.	Technicians no longer need to create database rows manually before editing and linking CAD drawings.
Database Integration	Micro-Audit Zoom & Navigation	Single click highlights the database row; double click zooms the camera to the space.	Saves hours of hunting through large complex layouts during technical audits.
Database Integration	Downstream CAFM Sync & Automation	Committed links instantly publish updated plans for occupant requests and automated PDF printing.	Eliminates delays between drawing updates, occupant request routing and printed reports.
Asset & Occupant Tracking	Seating & Ownership Timeline	Link individual CAD spaces directly to historical occupant and seating data.	Permits immediate auditing of vacancy rates, historical seat use and departmental cost allocations.
