The ARCAD Systemhaus offers with the CAD and AVA system a professional industry-specific solution for the operating system LINUX.
As on a 3D volume model based software ARCAD offers you a quick mass calculation and quantity calculation, an automatic generation of views as well as an integrated visualisation.

All required data of the planner can be obtained from the 3D model.
A user-friendly face and an comprehensible operator guidance allow to the experienced CAD user as well as the new beginner quick results while learning the program.
The user sees a tidy operator interface when starting the program first.
Many commands are directly executable with the mouse, because the commands are directly bound to already edited objects.
The integration of the AVA and the visualisation (Quickshader, Raytracing and Radiosity) allow a generally concurrent work without time-consuming program changes.
In addition, there is a huge number of interfaces for the handing over and takeover of data from programs of other providers.

Of course ARCAD allows you also the traditional work on the drawing board.
You can decide any time which approach corresponds to your momentary requirements best of all.

The automatic intersection of wall, roof and cover constructions, freely placeable and scalable wall openings for single- and additional-leaf brickwork or the dimensioning appropriate for DIN is only a small assortment of all possibilities.

A picture says more than many words.

A picture says more than many words.

Ideas will become rooms and plans are easy to understand.
ARCAD is a future-oriented CAD system with a wide user's basis under Linux and its circulation is becoming greater and greater.
ARCAD is suitable for any architecture office in every capacity phase.



ARCAD represents the quintessence from architecture, software know-how, modern computer capacity, consistent enhancements without compromises and more than 20 years of experience.

All conceivable components can be created by the 3D volume model of ARCAD and the completely free construction possibility in the 3D space.
Any construction is possible from the simple 2D-wall, the 3D-walls, single- or additional-leaf, concrete ceilings, foundations, simple gable roofs or complicated roof intersections over to rotational solids up to the most complicated solids by means of Boolean operations.

Of course a CAD like ARCAD makes a comprehensive assistance available.
Every command of ARCAD is exactly documented in the manual.
In addition, a help is also performed in a printable information window representable any time on the display.
Moreover, there are extensive tutorials to the different subjects which allow an intensive selfstudy of the CAD system.
The smart command explanation which belongs to every command simplifies in addition learning the CAD system without long training time.

ARCAD is a complete solution for the plan development in layout, view, sectional drawing and detail.
ARCAD offers you as an integrated system high plan quality, accuracy as well as all options of the planning presentation.
According to your individual preparation these drawings are pasted in the predefined drawing border of the character sheet.
The entries which are placed on the character sheet will be passed on with your entries of the scale (1 to 100, 1 to 50, 1 to 10 etc.) to the printing routine and accordingly plotted.
You can integrate texts and dimensionings into different TRUETYPE font parameter with free corner entry also as a long text.

    Generates free openings.

    With ARCAD you can construct in 2D as well as in the 3D range and look at.
    ARCAD owns a function with which you can create automatically different openings.
    Besides, you can set different parametres.
    These values serve as a basis to create them the opening to be generated.
    A new element which you can further use in all other drawings and models is generated.
    You place this opening at places in the brickwork which you can freely define.
    Afterwards you move the independent openings or exchange this for other types.
    All views are selected during the work by you with the mouse and are moved.
    Move the mouse, the perspective is also moved.
    Change the transparency of the brickwork around in order to set up your openings.

    raster image to vector file converter

    raster image to vector file converter

    You might use your existing drawings and convert them to CAD suitable files.
    Pictures are composed of small dots.
    ARCAD converts these dots to scalable vectors, arcs and circles.
    In addition ARCAD traces contours to polylines and arcs.
