CAD-Viewer.org is free and it can be used without any registration. Just note that since it requires a lot of resources (Storage, RAM, CPU, etc...), we are forced to put some limitations1.

- 1The limitations are subject to change without any notice.
- 2The storage refers to the total of MiB used to provide the service. For example, if you upload a CAD file and you decide to keep its source, the storage of such request is equal to the source plus our converted file. Once that the files expires, the storage is liberated.
- 3The IP restriction only applies to un-registered users but if a registered user uploads data under the same IP, he will also consume the unregistered-user data. Registered users sharing the same IP are not limited by this.
- 4It is not possible to ensure that all the files will be properly read and converted. CAD files are complex and some may include errors, if you have a problem with a conversion please contact us.
