From ACCA Software:
Primus-DCF is a free and complete software that allows Engineers, Architects, Surveyors and building contractors to easily create bills of quantities and estimates for the building industry through a very user-friendly interface.
Your monitor becomes your desktop where you will be able to open Price Books, Price Lists, Estimates and Bills of Quantities, consult them, insert, modify or copy parts of data from a source document to a destination document, and easily modify data with simple Drag&Drop operations.
Thanks to the WYSIWYG (What You See Is What You Get) technology, the document that you see while editing is exactly the same document you will get printed on paper. You can have different documents on your monitor and operate on any of them wherever you want by simply pointing your mouse cursor on the part you want to modify allowing you to work in a more direct and intuitive way.
