Since January 2009 Studio CAD is an official representative of CAD-PLAN Germany for Bulgaria.

CAD-PLAN software allows for drafting and increased efficiency of drafters in their daily work.

CAD-PLAN products are used primarily in design of steel structures, curtain walls, glazing etc.

CAD-PLAN’s ATHENA, FLIXO, SJ Mepla and CAD-Space provides a strong set of programs covering the needs of all designers in their daily work. Drawing and designing of all kinds of details, 3D modelling of structures, static calculations, higro-termic research, stress tests of glass structures.

CAD-PLAN’s products are easily interfaced with other programs in the industry.


athena - y2ATHENA is the leading AutoCAD based design software for curtain wall design and facade engineering on the market – and not without reason. Our software has been subject to consistent on-going development since 1989 and is used in metal construction companies, design offices and universities – in 16 languages and in more than 40 countries.

Matched exactly to our users’ requirements, ATHENA is a complete software package, offering practically everything to simplify the daily design tasks which confront the designer:


  • A 2D drawing environment with practical routines and libraries for producing elevations, cross-sections and workshop drawings.
  • A versatile 3D design section with the possibility of generating parts lists and production drawings automatically from a 3D design.
  • Powerful computational tools for structural analysis and building physics.
  • A sheet editing program for sheet design and development.
  • In addition, ATHENA is independent of profile systems and can be matched to individual needs.
  • Ideal for international design: ATHENA labels all the customer objects fully automatically and is able to translate a drawing into each of the 16 languages currently contained in ATHENA on the press of a key.

ATHENA Complete

athena-completeATHENA Complete is ATHENA which comes with an AutoCAD. It is a great and cheaper way to combine two very powerful softwares.

You can BUY or rent the ATHENA Complete package. Please, contact us for more information.

mepla - y2SJ MEPLA is the technologically leading program for dimensioning and calculating the stress on multi-layer glazing (plates). SJ MEPLA offers new approaches for stress calculation on laminated glass, insulated glass and point-supported glass – and for investigating pendulum impact and pressure shock.

The dimensioning and stress calculation of plate structures under widely varying conditions is a standard task in routine engineering work. A special challenge is frequently presented by geometrical configurations which deviate from a rectangular shape. They are no longer calculated using tables or rules of thumb, but rather using the finite element method.

In the field of glass construction the systems to be investigated are usually restricted to a few basic shapes (triangular, rectangular, …) for which new meshes always have to be produced. With the calculation of laminated safety glass units normally volume elements must be used.

The evaluation of the calculated results often occurs following the same pattern (deformations, stresses, verification) and until now it always had to be gleaned from the FE data.

And this where SJ MEPLA comes in:

All the input regarding the geometry, types of support, types of loading, computational formulations and required outputs are controlled and displayed using an input mask. The control and output of the results occurs visually via a dedicated graphical interface and by using a computational log which can be enclosed with the structural statics calculation.

Particularly, new FE methods facilitate the simple input and fast computation of sandwich structures (laminated safety glass), so that the normal problem situations can be solved in the shortest time (a few minutes).

SJ MEPLA is suitable for dimensioning and also for the structural statics computation.

The current version: SJ MEPLA 4.0

SJ MEPLA was complytely ported to 64bit (32bit is no longer supported)

flixo - y2flixo produces thermal-hygro analyses of the component and facade cross-sections. It has been developed by architects, computer scientists and physicists for architects, planners, energy consultants and building physicists.

With flixo thermal bridges, for example, can be detected at the planning stage and eliminated through changes in design. Consequently, building failures can be prevented and heating energy can also be saved. A further application is relevant to hygro-analysis, with which, for example, temperature minima on the internal surfaces of a cross-section can be determined in order to avoid the formation of condensed water or mildew. flixo analyzes two-dimensional component nodes for stationary boundary conditions (room temperatures and thermal transfer coefficients).
