Tailor Made Software has now added full interactive line weight controls inside the CADViewer user interface.
CAD Systems such as AutoCAD and MicroStation operates with a concept called default lines, in which a given lines keeps the same line width, independent on zoom level in the application, this concept has to be modelled when displaying CAD drawings in a web-environment based on physical width vector graphics objects.
In addition to the new interactive line weight feature in CADViewer, our back-end converter AutoXchange 2020, offers a rich interface to control the line weights and other controls, see Output Formatting.
