Description
The Export page Dxf tool saves a drawing page as a DXF file
Usage
- Select a Page in the tree view, if the document contains multiple pages.
- Press the
TechDraw SaveDXF button. - Select a location and file name.
Limitations
- Radial and Diameter dimensions will only export properly if they are "inside" the arc.
- Scaling is not supported. The DXF will be drawn in the actual size of the TechDraw page.
- Units are not supported. The DXF will be drawn in millimeters (mm). Dimension text will be shown exactly as displayed in TechDraw.
- TechDraw can't export a DraftView or an ArchView to DXF. These views are SVG elements generated internally by the Draft Workbench, so there is no geometrical shape to export. To export a view as DXF, it must have been created with TechDraw NewView or TechDraw NewProjGroup. For example, select an Arch SectionPlane, then use Draft Shape2DView to create a flat projection shape, and then use TechDraw NewView on this object. Alternatively, select the objects from the tree view or the 3D viewport, and export to DXF using File → Export.
- The title block of a page is an SVG template as well, so it will not be exported to DXF either.
- In general, TechDraw can only export to DXF those elements that are supported by the
Import::ImpExpDxfWriteclass of the Import Module.
Notes
- This function exports the R12 (AC1009) and R14 (AC1014) versions of DXF.
- R12 is an older, simpler version of the standard, but should be readable by most other software.
- R14 is the default version. It includes support for splines and ellipses among other things.
- There are 2 parameters that affect DXF output:
- Tools → Edit parameters → BaseApp/Preferences/Mod/Import → DxfVersionOut, valid entries are 12 or 14. Default is 14.
- Tools → Edit parameters → BaseApp/Preferences/Mod/Import → DiscretizeEllipses. If True, splines/ellipses are converted to polylines; if False, spline and ellipses are written as spline and ellipse objects. Default is False.
Scripting

The SaveDXF tool can be used in macros and from the Python console by using the following functions:
TechDraw.writeDXFPage(page,filename)
