# Sample with Kindergarten's building

![Experimental model of Kindergaten from Renga Architecture](/files/-MNLE-ywIyRltwkmPigm)

Let's write a coordinates in old and new system (to calculate parameters in our Application)

```
Renga Architecture
ChildrenGarden Gelendzhik
___________________________
Old System
39.068,21.075,-2.5
-8.281,21.075,-2.5
6.118,-4.275,-2.5
___________________________
New System
2216547.802,530046.2432,136
2216564.37,530001.8864,136
2216583.0789,530024.2462,136
```

Below two versions of IFC (2x3 and 4) in ZIP-achive:

{% file src="/files/-MNLD51YiM1IHTQByJqm" %}
IFC Building (Kindergaten) from Renga
{% endfile %}

After start a "Calculate"'s option you will get in app's console info:

```
