QCAD 3.4.0 comes with a new display mode for screen based line types. This is a solution to make line patterns visible for users working in larger or smaller units than Millimeters or Inches (for example Meters, Feet, etc.).
This is also the first release with support for custom properties enabled by default (QCAD Pro only). Custom properties are user defined key / value pairs that can be assigned to entities using the property editor. Custom properties are save to DXF / DWG and are typically used for further processing (CAM).
