The module represents the base of K3-Cottage complex. The 3D editor is designed for creation, storage and support of 3D models. Inherently, K3 is an independent system of geometrical, three-dimensional, solid-state modelling. The system is capable to solve a large variety of tasks in various branches of mechanical engineering. As the standard base elements for creating models the K3 system uses a number of linear and solid-state objects. The program linear objects include points, segments, arcs, circles, splines and contours. When creating base linear elements the designer is not limited to put contour points in one plane. The program solid-state base elements are a parallelepiped, a cylinder, a cone, a sphere, a torus, a prism, a pyramid, an ellipsoid and a spherical belt.

For creation of complex models the system uses generatix operations, Boolean operations and some other. One of the powerful and convenient ways of creating complex spatial objects is the use of generatix commands over the base elements. The example of such operation is creation of body of revolution, extrusion operation, creation of helicoidal surface, a surface tension over any nonplanar section by shift of generatix along the guide line. The program also supports Coons Patch, linear surfaces and sewing surfaces into one. At creation of comlex 3D objects the program applies both forming operations and Boolean operations. Operations performed with 3D objects are:

• Association of objects;
• Subtraction of objects;
• Crossing of objects.

When working in K3 execution of a single command or indication of the required object or a group of objects shows the detailed mechanical characteristics of this object. Such characteristics are volume, surface area, mass, inertia moment, etc. Thus the appearance of model is not the sole characteristic that you get about the object. The particular real objects carry much non-geometric information such as cost, the workpiece identification number, date of manufacture. For presentation of a model as real world object the system gives an opportunity to assign non-geometric information to the objects. The information is represented in the form of attributes - by numbers and texts. The user himself defines the number of the necessary attributes, assigns names and type. The created attribute can be further assigned and edited. The K3 system provides the transfer of information about the object to various databases through the ADO interface. For example, this feature allows to receive easily the specification on the equipment placed indoors. K3 does not hold to its own method of data storage. The advanced subsystem of data import and export gives an opportunity to exchange the geometrical information with other widely used systems. The supported formats include such formats of data storage as DXF, FRG, HPGL, STL.

The package is intended for creation of roof of arbitrary shape.

The package allows to create roof slopes, to determine slope crossing lines, to remove unnecessary elements. When creating slopes the system allows to set cantilevers, inclination angles, structure thickness. The package provides filling slopes with truss elements, creation of lathing. Besides, the walls could be cut by the use of slopes. The package accelerates and considerably simplifies the creation of roof of the house.

The package is intended for design of the house cabin.

The package allows to create house walls, to cut out windows, doors, apertures and to put flooring beams and to fill floor, walls and ceiling with boards. As a result of work the designer gets the complete set of reports required for manufacture and assemblage of a cabin. The module is the core of the K3-Cottage complex. All other packages are the addons to the Cabin package.

The package allows to transfer the geometry data from ArchiCad.

At data transmission the package controls the integrity and consistency of the information created in ArchiCad. ArchiCad is an architectural system whereas the K3-Cottage is a production and processing system. Sometimes the ArchiCad projects are not precise, with wall crossing angles incongruent by + - 1 degree or with "slightly" cut logs. For preparation of log drawings manual and automatic adjustment of model is required.

The package is intended for design of numerical-controlled instructions for woodworking plants equipped with NC machine units.

Currently the system provides connection with Krusi CMI 4x4, Stromab AutoBlox, Shmidler, Makron machines. The package allows to transmit the project technical information directly to the machine operating program.
