Supported standards

LINEAR has always stood for standard-compliant calculation and design. It is both our concern to always offer the latest standards and to constantly expand the range nationally and internationally. An up-to-date overview of all supported standards can be found in our knowledge base at [LINK].

  • IFC import of the architecture
  • IFC export including all metadata
  • Selection of the disciplines to be considered for the export
Visibility control

Visibility control with one click for:

  • Building parts
  • Floors

Language selection for interface and printouts

We provide you with no less than seven languages, which you can use and combine as you wish, either as the interface language or the print language. In this way, it is possible to design in one language and print in another. This is a great advantage, especially for international projects, as time-consuming translations are no longer necessary. There are no additional costs for the language packages.
The following languages are currently supported:

  • German
  • English
  • French
  • Dutch
  • Russian
  • Turkish
  • Italian
