 Hello everybody. My name is Kasper Hanung and I'm a tailor-made software. And what we are accomplishing in NextCloud is to enable CAD collaboration. And what is CAD? Computer-aid design. That's everything what we live in. That's our streets. This building is an architectural structure that's represented and a drawing in its construction, in its lifetime. And that is what we want to enable in NextCloud. So the problem is that many professionals in the construction, with their state industries and government, need to be able to share their CAD drawings and collaborate around these projects. And they want to need to do that in a secure basis. And this is where this beautiful NextCloud platform comes in, because that gives you the secure way of handling your files. What we did, we tailor-made with offices in Seattle and Stockholm. We have with a partner in the UK and in Birmingham, who has used NextCloud as a platform. And they share their drawings among all their clients and partners around Europe. So we built this app for this particular purpose here. We have integrated our CAD viewer, CAD conversion platform directly inside NextCloud, so there's no external access thereby ensuring that all customer content is completely secure. The way it works is that we have our own app structure. We have set the mind types for all the large CAD packages, the AutoCAD, the microstation, and as well as TIFF, to our application. Let me go here. We go in whenever people click on a file. We go into NextCloud folder structure, put that into our system. We native code convert that into cache, where after we have implemented a VJS encapsulation that goes into the NextCloud front-end, where it's then displayed. In display, we use the VectorGraphics standard W3C SVG standard, which is uniformly supported on all browsers and all platforms. With that, we add a number of specific extensions in order to specifically handle CAD. We need layer manipulations. We need ability to measure. We need transformations. So we also can handle a printable to scale and stuff like that. The typical use case is that a user goes in and upload an AutoCAD or microstation floor plan into the system. In this case, NextCloud. They want to display the floor plan and do layer manipulation measurement printing. They want to annotate it. It's typically a process where you go in and you want to change things and communicate those. And in that case, collaborate around the floor plan. And you may want to publish this drawing, this floor plan with annotation, red lines in a process where it can be either encapsulated in the system itself into NextCloud or it can be externally shipped off as a PDF. Then there are some advanced features where we have where you can sort of compare drawings to each other to show differences. I'll show that very much in the end. And there are some admin features that handle fonts, et cetera. That's very CAD specific. This is typically how it looks inside NextCloud. I got this guy here. There will be a menu bar at the top, our icon bar. We have then three skins where you can go in and do all that kind of stuff you want to do with the cat, like measuring, handling of it, red lines. And we even enable the standard collaboration interface so you can share and talk about it inside NextCloud. This here is a typical use case where we took the drawing before. We go in and the user will go in and set layers so that they only got a set number of layers for the specific case displayed. And they then go in and redline it, use the redline interface to talk about it, what they want to done with this thing here. And what we do here is that we have an ability to go in and create a PDF that then gets stored in a marker folder for sharing. And this is a process that we have integrated into NextCloud and it's very well used. And once that is done, then that PDF with the annotation in it can then be loaded in or, you know, externally distributed to the partners that are working on this project. Here I'm showing something that's quite interesting. This is a real data. This is a railway station somewhere in Europe on a very large national railway network. And what's happening there is that there is a ability that you can load in two different drawings and then comparably compare them to each other and see, you know, okay, what have been added, what have been changed and what have been deleted. So this is in this particular organization uses this tool to be able to see, okay, what have happened to my signals over time whenever, you know, you upload a new version or this is two specific drawings that is then being uploaded and then compared. And what was very, very interesting here is that we learned today that NextCloud version six has a version control now where you can name the versions, which means that you can actually, for the whole construction industry now, using stuff like this where you can go in with a logical algorithm and actually visually, you know, display the changes over your, over the versions inside NextCloud. So that's something we're going to very much explore with developers, you know, during this time here. So I guess that's it. We finish off here. Thank you very much.
