About us


The name Éptár was created back in 2002 by ArchiData Kft. Back then our company was making BIM solutions for ArchiCAD and other CAD software for 5 years already.

In 2006 Éptár was separated from ArchiData Kft. and started to develop exclusively GDL content and Add-ons. In the last 12 years our company developed more than 50 solutions and over 200 GDL library.
