FAQ
ILI to STP Conversion
What are ILI files?
ILI is the model file of INTERLIS, the Swiss standard for describing and exchanging geographic data. Before data are passed from one office or program to another, the agreement on what exactly the data contain is written in a file of this type: which kinds of objects exist, such as parcels, buildings, and roads, which attributes each has, how they are related, and which rules the values must obey. The data themselves are not stored here but in separate transfer files, so that one model can serve many deliveries. INTERLIS was created in Switzerland in the 1990s for cadastral surveying and is now mandatory for official Swiss geodata, and it is also used in other countries. There are two versions, INTERLIS 1 and INTERLIS 2, and both use the .ili extension for models.
What are STP files?
STP is a file format used by popular CAD software. STP contains 3-dimensional data saved in the Standard for the Exchange of Product Data (STEP, ISO 10303) file format.
