BSI uses various software such as AutoCAD, Photoshop, Solid Works and Acrobat to prepare your drawings as well as make changes to any hard copies you may already have. Distance is not an issue. Drawings can be shipped, or emailed in whatever file format you require. The most preferred method is a PDF file format using Adobe Acrobat Reader. From Acrobat Reader, drawings can be viewed and printed directly from your own computer.
