Founded in 1989 in Aachen , LINEAR became a worldwide innovator in digitizing the design of building systems by providing software solutions and services for the MEP design. The brand stands for competence in technical calculation and CAD design applications within BIM processes. Initially conceived as a pure schematic drawing tool, LINEAR today offers the largest product portfolio of design software for building services engineering from a single source: drawing, calculation, simulation and 3D design programs – 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. In addition to our solutions, we are represented in the market by the OEM software of our industry partners with more than 20,000 registered workplaces.

We have been grown into a healthy and independent software company with thousands of customers from design offices, trade and industry. Our employees are dedicated engineers and technicians, who combine deep knowledge of the MEP industry and leading CAD-platforms with the latest software development tools.


Every day, our customers produce thousands of drawings and calculations and our solutions prove themselves worldwide in demanding projects. 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 “PSR Partner” and a Microsoft “Gold Certified Partner”. 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.

What moves us, is our common mission: The best software solution for better buildings.
