Construction lines that extend to infinity in only one direction are called rays. The term construction line usually refers to xlines, which extend to infinity in both directions. You can create construction lines that extend to infinity in one both directions. Specify the endpoints of the next segments. To draw a line From the Draw menu, choose Line.

If you need to draw a series of line segments as a single object, use a polyline. Use lines if you want to edit individual segments. A line can be one segment a series of connected segments, but each segment is a separate line object. The default linetype is CONTINUOUS, an unbroken line, but various linetypes are available that use dots and dashes. In general, you draw lines by specifying codinate points, properties such as linetype col, and measurements such as angles. You can create a variety of lines: single lines, multiple line segments with and without arcs, multiple parallel lines, and freehand sketch lines. To export objects to DXF use the export method of the importDXF module.1 Drawing Lines, Polygons and Rectangles The line is the basic object in AutoCAD. See also: Autogenerated API documentation and FreeCAD Scripting Basics. See Import Export Preferences and FreeCAD and DWG Import for more information. LibreDWG (open-source, lacks support for some DWG entities).There is built-in support for the following DWG converters: So asking for DXF files instead of DWG files, and supplying DXF files in turn, should not cause any problems. All applications that can read and write DWG files can do the same with DXF files, with no data loss. Note that the DXF format allows a 1:1 conversion of the DWG format. When exporting to DWG the opposite conversion happens: the DXF created by the FreeCAD DXF exporter is turned into a DWG. To import a DWG file a converter is used to create a DXF first, which can then be processed by the FreeCAD DXF importer. That is why FreeCAD relies on external converters to read and write DWG files. When groups are nested, the deepest group gives the layer name.įor licensing reasons, the required DXF import/export libraries needed by the legacy version of the importer are not part of the FreeCAD source code.įor more information see: FreeCAD and DXF Import.īecause the DWG format is a proprietary, closed and undocumented format it is hard for open-source projects like FreeCAD to support it. Layers are mapped from layer and group names.Black is mapped to 'ByBlock', other colors are mapped using AutoCAD Color Index (ACI) colors. The colors in the DXF are based on the line color of objects.Compound objects are exported as blocks.3D objects are exported as flattened 2D views.But ellipses, B-splines and Bézier curves are not exported properly. All FreeCAD 2D geometry is exported, except Draft Points.Note that a DXF created from 3D objects will contain duplicate lines. Straight edges from faces of 3D objects are exported, but curved edges only if they are on a plane parallel to the XY plane of the global coordinate system.All FreeCAD 2D geometry is exported, except Draft CubicBezCurves, Draft BezCurves and Draft Points.Some of the features and limitations of this exporter are:

Both formats can be handled by many applications. The legacy exporter exports to the R12 DXF format, the C++ exporter to the R14 DXF format.

blocks (only geometry, texts, dimensions and attributes inside blocks are skipped).

This importer can import the following DXF objects:

Both support all DXF versions starting from R12.ģD solids inside a DXF file are stored under a binary ACIS/SAT blob, which at the moment cannot be read by FreeCAD.

One is built-in, C++-based and fast, the other is legacy, coded in Python, slower, and requires the installation of an add-on, but can handle some entities better and can create more refined FreeCAD objects.

Two importers are available, which one is used can be specified under Edit → Preferences. Qcad drawing exported to DXF, which is subsequently opened in FreeCAD Importing

Draft DXF is a software module used by the Std Open, Std Import and Std Export commands to handle the DXF file format.
