The liNear GmbH

liNear GmbH is an innovative supplier of software solutions and services for HVAC, plumbing and plant design. Since 1993 this brand from Aachen, Germany, has been standing for competence in technical calculation programs and CAD applications. Initially conceived as a pure schematic drawing tool, liNear has been offering probably the largest product portfolio of design software for building services engineering from a single source: drawing, calculation, simulation and 3D design programs – for more than 25 years. Seamlessly integrated, easy to use and therefore easy to learn.

Our solutions are developed together with designers, construction companies and industry partners in a trusting relationship. Especially the cooperation with our industry partners helped us to get into the product details, with many advantages for our customers: easy handling of complex systems and processes, planning reliability also for product innovations and finally complete bill of quantities with all articles for offers and tenders. The permanent development of our software enables customers to respond to the fast-paced demands of their business with appropriate tools.

Starting in 1993 as a small company with 6 employees, it has grown into a healthy and independent software company with thousands of customers from planning offices, trade and industry. In addition, we are represented in the market by the OEM solutions of our industry partners with more than 20,000 registered workplaces. With the increasing number of workplaces, the responsibility to ensure data compatibility for further developments has grown as well.

Every day, our customers produce thousands of drawings and calculations at high work and cost. The fact that these can be safely migrated when switching to new operating systems, CAD versions or even when standards are changed has always been and still is our first priority.

liNear is an Autodesk “ISV Partner”, a Microsoft “Gold Certified Partner” and part of the Fujitsu “Alliance Program”. By these, maximum compatibility of the software is ensured. It is probably the combination of creativity and continuity, qualified sales engineers, support and training offers and of course the constructive feedback of our large user community, which in the end leads to professional software and last but not least to investment security.
