Inkscape drawing exported to SVG, which is subsequently opened in FreeCAD
The following SVG objects can be imported:
- PATH objects
- LINE objects
- RECT objects
- CIRCLE objects
- ELLIPSE objects
- POLYGON objects
- POLYLINE objects
FreeCAD will not import path objects that have only one point (forum discussion).
The following FreeCAD objects can be exported:
- Lines and wires (polylines)
- Arcs and circles
SVG is a 2D format, so all Z information will be disregarded (all objects will be flattened).
When exporting, a User Unit (px) equals one millimeter.
When importing, the width, height and viewBox attributes are respected. All elements are scaled to their size in millimeters, which is FreeCAD's internal unit. If the SVG does not contain information on its physical size, it is assumed to have a 90 DPI resolution. Using absolute units in attributes inside the SVG should be avoided. Relative units like em, ex and % are currently not supported.
The Inkscape SVG Editor currently works only with 90 DPI documents. No matter which unit is selected in Inkscape. All the output has to be considered converted to 90 DPI and rounded to 6 decimal places. As FreeCAD (and the SVG standard) is agnostic to the precision of rounding done in Inkscape these values will not be rounded on input. And odd values in millimeter will remain. If you need the SVG import not to be rounded, work on User Units (px) in Inkscape. Scaling can be done after the import in FreeCAD or by changing the width, height and viewbox attributes.
To export objects to SVG use the
export method of the importSVG module.
- For the Windows OS: use a / (forward slash) as the path separator in
import FreeCAD as App import Draft import importSVG doc = App.newDocument() polygon1 = Draft.make_polygon(3, radius=500) polygon2 = Draft.make_polygon(5, radius=1500) doc.recompute() objects = [polygon1, polygon2] importSVG.export(objects, "/home/user/Pictures/myfile.svg")
