Network topology diagram software
Network topology diagrams. Without the complexity.
Map network devices, connections and communication paths in a straightforward editor built for technical documentation — from everyday IT networks to industrial Ethernet and OT architecture.
Place switches, firewalls, PLCs and SCADA servers, connect them port to port, and keep cable, IP and VLAN information on the objects instead of in loose text.

Network drawings that stay connected.
Generic diagram tools leave you aligning lines by hand. In InduDraft, links belong to the devices they connect, so the drawing stays tidy when the network changes.
How to create a network diagram
- 1
Choose a template
Start from Industrial Ethernet, Basic IT, Redundant ring or IT/OT architecture — or start blank.
- 2
Place equipment
Search the Network & Communication library and place devices on the canvas.
- 3
Connect ports
Drag from a device port to another device. Choose copper, fiber, wireless, serial, fieldbus or logical path.
- 4
Document and export
Add device names, IPs, VLANs and cable IDs, then export PDF, SVG or DWG.
Built for real network documentation.
Intelligent connections
Links attach to ports, follow devices when moved and route orthogonally. Several links per device.
Distinct line types
Copper, fiber, wireless, serial, fieldbus, logical path and redundant links — by pattern, not colour alone.
Device data
Device name, manufacturer, model, IP and MAC address, subnet, VLAN, location, rack and interfaces.
Cable data
Cable ID, ports, cable type, speed, protocol, VLAN and length. Duplicate cable IDs and IP addresses are flagged.
Zones and conduits
Security zones, DMZ, subnets, VLANs and site containers to show network boundaries.
Physical and logical views.
Draw the physical network with switches, cables and ports — or a logical architecture with zones, firewalls and communication paths. Logical paths have their own line style so they are never confused with cables.
Network objects instead of loose shapes
A network diagram is only useful if it is correct and easy to update.

Use InduDraft for practical network work
Industrial Ethernet
PROFINET or EtherNet/IP networks from SCADA and HMI down to PLCs, remote I/O and drives.
IT/OT segmentation
Document enterprise, DMZ, operations and control zones and the conduits between them.
Redundant rings
Show MRP rings and redundant paths clearly for commissioning and maintenance.
Supplier and as-built documentation
Deliver clear network drawings with packaged systems and keep them updated.
Standards and conventions referenced
Network topology icons are not defined by a single graphic symbol standard. InduDraft uses its own vendor-neutral symbols and supports documenting concepts from these references.

InduDraft is not certified or endorsed by any standards organisation, and drawings are not validated for compliance.

DWG export produces editable 2D CAD geometry, not intelligent network objects.
Network topology software questions
What is a network topology diagram?
A network topology diagram shows the devices in a network and how they are connected — physically (cables, ports, fiber) or logically (subnets, VLANs, zones and communication paths).
Does InduDraft support industrial (OT) networks?
Yes. The Network & Communication library includes industrial switches, routers and firewalls, PLCs, safety PLCs, remote I/O, RTUs, DCS controllers, HMIs, SCADA and historian servers, gateways, drives and networked field devices.
Are connections real or just lines?
Connections attach to device ports and stay attached when you move equipment. Each link stores its connection type, cable ID, ports, cable type, speed, protocol, VLAN and length as structured data.
Can I draw IEC 62443 zones and conduits?
You can draw labelled security zones, place equipment inside them and draw conduits as labelled logical paths, following the IEC 62443-3-2 zone and conduit concept. InduDraft does not calculate security levels or verify compliance — the diagram is documentation.
Can I show redundant networks such as MRP or PRP?
Yes. Mark any link as a redundant path (shown as a double line) and label the protocol, e.g. MRP, PRP or HSR. InduDraft documents the design; it does not simulate the protocol.
Can it discover my network automatically?
Not yet. Automatic discovery, LLDP/SNMP import and config-based generation are not available. Diagrams are drawn and edited in the editor.
Can I export DWG?
Yes. DWG export works today for signed-in users. It produces editable 2D CAD geometry, not intelligent network objects. DWG is planned as a Pro feature after the preview period.
Is InduDraft free to try?
Yes. Open the network editor in your browser without creating an account.
