Online IFC editor: edit your model with nothing installed

Open an .ifc file in your browser and actually edit it: properties and Psets in batch, delete elements, merge files, move and georeference the model, and download the modified IFC. Your files are never uploaded — everything runs on your machine.

An IFC editor is not an IFC viewer

Almost everything you find searching for "IFC online" is a viewer: it opens the model and lets you look at it, measure it and little else. An IFC editor changes the content of the file and gives you back a valid IFC you can push into your workflow. That is what Geoma does, and it is why it helps when a model arrives from another team with the data wrong and you don't want to — or can't — open Revit.

What you can edit

Properties and Psets

Change any property value from a spreadsheet-like table, create new properties and organise Psets (native, eCOB, manual, BaseQuantities).

Batch editing

Apply a property to hundreds of elements at once: by IFC type, by filter, by GUID list, or by whatever you select in the 3D viewer.

Delete elements

Remove elements without leaving dangling references or breaking the spatial structure, and check it in 3D before downloading.

Merge files

Insert the content of one IFC into another, with schema detection and conversion when needed.

Move and georeference

Translate, rotate and place the model in real UTM coordinates, honouring IfcMapConversion or the IfcSite placement.

Export

Download the modified IFC, or take the data to CSV/Excel, the view to DXF and the issues to BCF.

Editing an IFC, step by step

  1. Open the file. Drag the .ifc onto geomaifc.com/app. It is processed in your browser and supports IFC2x3, IFC4 and IFC4x3.
  2. Find what you want to change. Filter by IFC type, text, property or chainage, or select it straight in the 3D view: table and model stay in sync.
  3. Edit. Change a single value in the table, or use batch editing to apply it to the whole selection. Ctrl+Z undoes.
  4. Check in 3D. Measure, section and isolate elements to verify the result before exporting.
  5. Download the modified IFC. The original file on your disk is never touched: you get a copy with the changes applied.

Batch editing is what saves the day

The usual case: a model with 20,000 elements arrives and a control property — phase, contract, asset code, subsystem — must be filled in on every element of a type. By hand that is hours; in batch it is a filter, a value and apply. Geoma also validates the model against a required-property template in Excel, so you can see at a glance what is missing before you deliver.

If what you need is quantities (volumes, areas, lengths for every element), that lives in the automatic quantity take-off, ready for Excel.

What it does not do

Geoma does not model: it will not create a wall or reshape an element. It edits the data, the position and the composition of the model. If you need to redesign geometry, that belongs in your authoring tool; if you need to fix, complete, clean up or relocate an IFC that already exists, that is exactly this editor's job.

Frequently asked questions

What is an IFC editor?
A tool that opens an IFC and lets you change its content — properties, Psets, elements, position or georeference — and save a new file. A viewer only lets you inspect it.
Are my files uploaded anywhere?
No. The IFC is processed on your own machine with WebAssembly; it never leaves the browser.
Is my original file modified?
Never. Changes live in memory until you press "Download IFC", which gives you a modified copy.
Which IFC versions are supported?
IFC2x3, IFC4 and IFC4x3 — the last one being the schema for infrastructure and linear works.
Can I edit properties on many elements at once?
Yes, that is exactly what batch editing is for: by IFC type, filter, GUID list or 3D selection.
Does it work on iPad?
Yes. One finger selects and measures, two zoom and pan, three orbit.
Is it free?
Opening, viewing, measuring and sectioning is free and needs no account. Batch editing, merging, deleting and exporting are in the paid plans, from €19/month. See plans.
