A map on the ground under the model
Lay a street map or aerial picture on the ground under a georeferenced IFC model, from map tiles, map services or a picture with a world file.
Written for BimCraft 0.5. The same help is inside the app: press F1.
What you'll do
See the model in its place: the site's street map or aerial picture on the ground under it.
Steps
- Open an IFC model that carries its place on the map (a map conversion, IfcMapConversion, with a projected coordinate system). Exporters write it when the project's coordinates (survey point, shared coordinates) are set.
- Choose Show › Map layers…. The dialog says the model's system, for example EPSG:28356. A model without a map conversion cannot have map layers: the dialog says so.
- Turn on Map layers from the internet. Until then nothing is asked of any server; when it is on, the servers you add see the area round the model and your internet address, never your model.
- In Add a layer choose tiles (an address with
{z},{x}and{y}), a WMS, WMTS or ArcGIS service (Get layers, then choose one), or a picture with its world file. - Close the dialog. The map lies on the ground just under the model's lowest point, over the model's footprint and as far again round it.
