After positioning of mouse cursor (without pressing of any key) on required element, a cloud with short information concerning application of this element will appear. Clouds have also another function – they display less important or partial calculation results. It is so for example in partitions edition window, where the hint cloud displays pictorial diagram illustrating temperature drop on individual layers of partition. To display this information, just position the mouse cursor on special field: . Sometimes the cloud is not available and then the colour of field disappears . Such situation can take place, when calculation is performed with error, entered data are incorrect or when the hint field does not concern actual partition or compartment (for example temperature drop diagram is not drawn for a wall at the ground, for partition with imposed U).

The User can enter in document window all project data and select the calculations options. Here are performed thermal calculations for the building presented in project.

By means of these buttons the windows can be minimized, inserted into working area of main window or closed.
