There are multiple specifications of IFC. What should I use?

Currently Tridify supports IFC 2x3 format, so make sure to select the correct format when you export IFC files.

When can we expect IFC4 support?

IFC4 support is something we are working on. For now Tridify supports IFC 2x3.

Why does your service only support IFC formatted files? Why not FBX, SMC …

IFC format is a global standard that is not controlled by any specific company or linked to any product. Customers using our service have the possibility to use any design software that supports IFC export.

Why IFC format?

IFC files not only have 3D data but also the whole data set for each object set in the CAD software. This means that our software can recognize different types of objects like a door, windows, etc. Additionally, you get all the data originally inserted to the objects, for example manufacturer, phase of construction, etc.

How do I get IFC files?

All major 3D architecture and CAD software have an IFC export functionality (ArchiCAD, Revit, Tekla, VectorWorks etc). More information about software that supports IFC go to buildingSMART International

What is IFC?

IFC is an acronym for Industry Foundation Classes. It is an ISO/PAS 16739 standard file format that includes 3D data and associated object data. IFC files have file extension .ifc. IFC is a human-readable ASCII file format so it can be opened with a text editor.

Plans & Billing

The service is subscription based. What does that mean?

When you buy a subscription plan the subscription is valid until cancelled.
The subscription is renewed automatically every month if not cancelled.
Your credit card is automatically charged monthly, at the beginning of every subscription period, unless the subscription is cancelled. If cancelled, the subscription is valid until the end of the paid period.
Learn more about our pricing plans.

Tridify has multiple plans. Which plan should I select?

When selecting the best plan for you, the main thing is to consider how large will your IFC files be. If you have large IFC files you need more IFC storage space to be able to convert the files. If you have lots of small files you should consider how many times you need to convert the files per month and choose the plan accordingly. Find out more about our pricing plans.

How does the conversion count work?

Every plan has the maximum amount of conversion per month. The conversion count resets to zero on the start of every subscription month - this won't effect already converted files.

How does the IFC file storage work in the plan?

After uploading your file to the service, you'll see how much storage you have left. If the storage limit has exceeded, you’ll need to remove files from the storage to continue using the service. The storage space will not reset to zero every month; the files uploaded to the IFC storage are using your storage capacity until they are removed. See our pricing plans.

I want to upgrade my plan to bigger plan. How do I do this?

In your account, go to ‘My plan’ by clicking ‘My plan’ from the top right corner. From there you can change your subscription by selecting ‘Change plan’.

Tridify has multiple subscription plans. What is the difference between the subscriptions?

The subscription plans are defined by two things: IFC file storage and amount of conversion. The bigger the plan, more file storage and conversions you’ll get. Find out more about our pricing plans.

Where can I find my receipt/invoice?

Receipt for your payment will be sent to the email address used in your Tridify account within a few minutes after each payment.
An email receipt will be sent from Stripe (online payment system) with the title/subject "Your receipt from Tridify".
If you can't find your receipt check your Junk/Spam folder.
Still not able to find your receipt? Contact Support

What happens to my conversions and published models if I downgrade my plan?

If you choose to downgrade your plan and have more uploads in storage than your new downgraded plan allows - all of your current uploads and published models will be frozen. You can delete files and conversions to free up some space. When you have enough free capacity (according to new plan) all of the remaining uploads and published conversions will work again. Nothing will be deleted unless you choose to do so.

Who is eligible for a free educational plan?

Individuals who study or are employed in an educational institution. A valid educational institution’s email address is required. Educational plan has 50 conversions per month and a total storage capacity of 200MB. See on this page: How does the IFC file storage work in the plan?

Apply a free Educational plan

Please note the Educational plan is
- valid for 12 months after which it has to be renewed
- for non-commercial projects only

How can I cancel my subscription plan?

If you choose to cancel your subscription plan, it will remain active until the current billing period ends. Your credit card will no longer be charged after the cancellation date. After this date you are still a user of the service, but neither you or your project members can upload or access the files in your projects. As a member, you will still have access to shared projects owned by other users.

To cancel your subscription plan, sign in to Go to your Account (top right corner) and in 'My Plan' click 'Cancel Plan'.

Security of Service

Are my uploaded files secure?

Our automatically scalable cloud service is situated on Amazon AWS cloud service and is created according to AWS's most secure service guidelines. This means that the AWS security team is automatically protecting our service security. Once your file is uploaded using an encrypted connection, the files are saved to an encrypted file service that can’t be decrypted without AWS's decryption service. The files uploaded to our file server are more secure than on most computers in any company premises.
AWS implements and maintains technical and organizational security measures applicable to AWS cloud infrastructure services under globally recognized security assurance frameworks and certifications, including ISO 27001, ISO 27017, ISO 27018, PCI DSS Level 1, and SOC 1, 2, and 3

Who owns the data/file once it has been uploaded?

You, as a user of Tridify Service, retain all ownership of the data/file you have uploaded to Service.

Who has access to my uploaded files/IFCs?

Only those with whom you share your project with.

Tridify Web Conversion Service

I have converted my IFC in Tridify, what now?

Now you can choose to publish your model! Here's a tutorial how to Publish BIM to web.

How do I delete my uploaded IFCs?

You can choose to delete your uploaded IFCs if you don't need them anymore or to free up space in your plan. Please note, that deleting an IFC will also delete all published URLs that are linked to the deleted file.
You can delete an uploaded file by clicking More Options menu (three dots) next to your file and selecting Delete file and conversions...

How do I get access to the Tridify web conversion service?

Our Tridify web conversion service can be found here: To be able to use the conversion service you need to register and log in to the service.

Do you have any tutorial videos?

Yes we do! Please find them in Tutorials and in Youtube.

Can I download my converted file to any other application other than Unity?

Currently you can access the converted file only from the Tridify BIM Tools plugin for Unity. We are working on other solutions. However, you are able to publish your BIMs straight to web - without any applications or software. Find out more here.

What is the result of the conversion?

Results of conversion are: - glTF formatted 3D files - publish to web by using Tridify Viewer or download via API - DAE (Collada) formatted 3D files with the original IFC file data attached - for you to access in your Unity project (requires the use of Tridify BIM Tools)

I have uploaded my files to Tridify. What now?

If your file has been validated you can choose of different conversion methods:
- Split by storey: All floors in the IFC file will be separated into their own files. Recommended when using Tridify Viewer or our Floor Lighting tool in Unity.
- Generate Ceiling Slabs and Extras to Storeys: Upper storey floor slabs and lower storey stairs will be appended to each storey as 2 additional files. This is useful to get complete single storeys with less memory usage in Unity.

You can discover more about your next steps in our tutorials and videos.

The validation failed. Why did this happen?

There are several possibilities why this could have happened.
1. A wrong version of IFC file (IFC 2x3 is supported)
2. The file is not an IFC file
3. File is corrupted
4. File has wrong formatted IFC data
5. File has non-standard IFC data
In most of the cases the error message of the validation will give you detailed information about the failed validation.

Tridify is validating the file that I just uploaded. What does that mean?

The validation checks if the uploaded file is correctly formatted and makes sure that it can be converted correctly. The conversion parameter will change according to the findings of the validation, so you’ll have a better understanding of your file.

I have multiple IFC files in a single project. Can I pack them to a single file like zip, rar, gzip?

No. The file upload service doesn’t support packed files. However, you can upload multiple IFC files in parallel. Take a look at our tutorial on Upload IFC and Convert with Tridify.

Where can I check my current storage capacity and conversion count?

After signing in to our service go to your Account (top right corner). In 'My plan' you can check your IFC file capacity and monthly conversion count.

Is there any other format supported but IFC?

No, but all major 3D architecture and CAD software have an IFC export functionality.

Why cloud-based service?

Benefits of a cloud service for a client:
- maintain control over content
- flexibility to scale up and down quickly and easily - you’ll pay for what you use
- fully scalable service - free your computer for work
- upgrades happen automatically and instantaneously
- no significant investment in licenses or infrastructure needed
- no processing limits
- access your bim from anywhere with any device - supports also mobile working
- safe data storage - Tridify uses AWS cloud service as a cloud provider

Does your service reduce polygon count?

Our conversion service doesn't do poly count reduction. It is mainly meant for converting 3D solid geometry (used in CAD systems) into polygon models. The service makes some optimizing to the model to be able to generate UV-maps (IFC 2x3 doesn't contain texture mapping information). If you have exported a polygon model as IFC and then convert it in our service, the polygon count stays about the same.

How can I access my Tridify processed BIM model?

You can access your models in Unity by using Tridify BIM Tools.
If you are a web developer you can use Tridify API to bring your Tridify processed files into your app. Our tools for developers.
