Module fields now stay intact if later corrections of the roof outline are made and will not be deleted. Even single steps while correcting roof outlines can be made undone.
If module fields are drawn over roof edges or obstructions Base On calculates only modules which can be built. Invalid or automatically deleted modules can be made visible or hidden with an additional button in the view options.
The reference edge for module alignment is now marked with a green line. Though the module field will be deleted if the reference edge is changed afterwards.
The ballast optimisation or pressure and suction loads makes a basic ballast of 3 kg at the module field edges necessary. This is now implemented in and the assembly manuals will be updated soon.
