## 1.3. Co-operation with external applications

Except of applications of InstalSystem package the program Instal-heat&energy can co-operate directly or indirectly with other applications working in Windows system:

- MS ExcelŽ – export of results in form of tables.

- AutoCADŽ – import of data concerning building structure (storey plan views) – by means of Instal-therm program.

Building base (plan views of individual storeys) utilized for heat losses calculations can be imported from one or several files of DXF or DWG format, created by engineering graphical programs, for example AutoCADŽ. Such import can be performed with simultaneous interpretation of walls, windows and doors so that in result appropriate program objects can be created and compartments can be defined, or without such interpretation – then imported part of DXF or DWG file will be a drawing. On the background of this drawing it is possible to draw in Instal-therm program our own building base or installation plan. To enable correct file interpretation and recognition of walls, windows and doors as well as creation of compartments it is necessary to observe specified principles of graphical design (in application, in which the building project is created), which have been described in Instal-therm program manual.

Calculation results tables and bill of materials can be saved in worksheets (letter files) of MS ExcelŽ program. This makes possible presentation of calculation results in form of any statements and charts.
