![]() ![]() ![]() There are numerous techniques and standards used to design a PCB that is easy to manufacture and yet small and inexpensive. Usually an electronics or electrical engineer designs the circuit, and a layout specialist designs the PCB. This task has been made vastly easier with the advent of readily available PCB layout software, but it is still challenging. ![]() ![]() This may be due to the presence of nothing but straight polylines and the absence of arcs ( see inset #3).The efficient laying out of traces on a PCB is a complex skill, and requires much patience. Importing " Polylines.dxf" into the Pattern Editor shows no alignment errors. The DipTrace DXF export process apparently converts arcs into groups of polylines. Importing " Original.dxf" into the Pattern Editor yields small alignment errors with arc placement ( see inset #2).Ī second DXF file named " Polylines.dxf" was created by exporting the PCB Layout drawing. " Original.dxf" was then imported into the DipTrace PCB Layout editor with line widths purposely kept at 0 mm to clearly show there are no obvious alignment problems between individual elements of the imported drawing ( see inset #1). The Alibre Design drawing was carefully constructed with straight lines and arcs, employing tangent constraints and frequent error-checking with the Analyze tool looking for gaps and misalignments. A DXF file named " Original.dxf" was exported (AutoCAD 2018 format) from a drawing created in Alibre Design specifically for this post. ![]()
