This article contains information about the recommended system requirement to use Catenda Hub. Catenda hub can be accessed through the browser and does not need to be installed.
The following topics will be described in this article:
For regular projects (up to LOD 300):
Intel Core i5 or eq.
8 to 16 GB
integrated / 4GB
For Dense Geometry projects (LOD 400 and above):
Intel Core i7 or eq.
Although Catenda Hub is well optimized and can run most models some users might want to set themselves up for success as best as possible. Here are therefore some strategies that can be used to optimize your workflow in Catenda Hub:
Of course loading less models will mean less objects and therefore better performance
Turning on incremental rendering speeds up rotating around models with a lot of geometry as not all of the objects have to be loaded when rotating.
As a final step you can make a query of the section you are working in. Usually when you section off part of the model the objects are still in memory and just hidden.
With a query these objects are completely removed and it will therefore be easier to work with the model. Keep in mind that you will not be able to use property libraries with queries because not all objects are loaded.
Catenda Hub is available through different browsers.
Browsers that you can use to access Catenda Hub can involve:
Windows 11 system requirements:
Please make sure you are using hardware acceleration.
Hardware acceleration options for the different browsers can be found here:
Please check if you have any browser extensions or other programs that could be slowing down your Catenda Hub experience.
Best browser by memory usage:
If you are using fixed point size you might run into low fps when a lot of points have been loaded in. You might also experience points taking longer to load when the memory budget of your system is reached. Points closest to the camera are loaded first so if you want to load points at a specific location it is better to navigate to that position and then turn on the point cloud so it starts loading points there first.
To combat hitting the memory limit and getting lower fps you can lower the point budget so fewer points are loaded in.
Please make sure you are using your systems dedicated GPU and not the integrated GPU.
On Windows 10 you can make sure you use the dedicated GPU by following these steps:
Control the quality of your network, so that the ratio between Download and Upload is
around 1:10 or above.
(this is an example, not actual requirement)
Proxies and firewall:
Users accessing Catenda Hub behind a firewall, proxy or other intermediary need access to the following domains and ports for the application to function properly.
* means DNS wildcard and
. is a domain level separator, don't treat the below as regexes).
We encourage you to use this new domain name.
You should not run into problems with more sub-domains like
*.*.*.catenda.com but if you do it might be easier to allow everything from
The following domains will be maintained in the foreseeable future but not referenced in technical literature.
Catenda Hub uses the following services:
If you only intend to use Catenda Hub through one of our plugins you these are the only domains you need to allow through your firewall.
For authentication of plugins and integrations
For use of plugin
For use of integration
Solibri BCF Live connector
This port is optional but recommended for best in-browser user experience.
Protocol: TCP (For hub.catenda.com and www.hub.catenda.com only)
Clients that attempt to make a request on 80 are redirected to make the equivalent encrypted call on port 443.
Protocol: TCP + UDP
All Catenda Hub traffic is TLS-encrypted on this port.
UDP is optional but recommended for best user experience as it allows compatible browsers and other clients to take advantage of advances in the HTTP protocol, such as HTTP/3 (formerly QUIC) which we are rolling out across the platform.
