If you locate the Xref using Browse then you will further be asked if you want to add the folder in which the Xref was located, to the software's Xrefs Search Paths list. If not found in any of the above locations the software asks if you want to ignore the Xref or locate it using File Browse. the list of Search Paths as specified in the CAD Viewer DXFXREFS.INI file. The software searches for Xrefs in the following order: It may have a fully specified path, for example 'D:\TITLEBLOCKS\A1.DWG', or there may be no path, for example 'A1.DWG'. An Xref is a drawing external to the current drawing which is referred to or is inserted into the current drawing.Īn Xref will always be a reference to an external. For general AutoCAD DWG/DXF information and AutoCAD feature types supported by FME, please refer to the Autodesk AutoCAD DWG/DXF Reader/Writer.CAD Viewer 2020 supports DXF external reference entities, known as Xrefs. This chapter contains information related to the AutoCAD DWF reader/writer. Currently the DWF reader and writer can read and write sheets and models from two-dimensional (2D) DWF files. These are read separately by the AutoCAD DWF reader and writer. DWG/DXF files are read by the AutoCAD DWG/DXF reader and writer.ĭWF files are handled seamlessly but internally they undergo a different series of translation processes. Logically, both DWG and DXF files are identical and, therefore, FME treats both file types in the same manner.
DXF (drawing exchange format) files, which are large ASCII files,.There are three supported formats used by AutoCAD: Note: Throughout this chapter, the AutoCAD file is referred to as a drawing file rather than a DWF file. This chapter assumes familiarity with AutoCAD-compatible systems and the entities (features) that are manipulated within these systems.
When AutoCAD data is output, header information may be copied from a supplied template, or prototype, file.
FME also provides support for reading and writing AutoCAD DWF files up to and including version 6.0. AutoCAD drawing files consist of drawing settings and configuration, as well as a series of entities, or graphic elements, organized into layers.įME provides broad support for many AutoCAD entity types and options and for reading and writing AutoCAD DWG and DXF files with versions up to and including 2010. The AutoCAD ® Reader/Writer enables FME to read and write files used by Autodesk ® AutoCAD and compatible systems.
