Go to File > Import > AutoCAD DXF and find your file.

Go to Edit > Preferences > Add-ons > Import-Export: Import AutoCAD DXF Format (.dxf).

Open in your favorite 3D printing software and have a go at printing it.

Save as STL for printing: Click Design -> Save as STL (this could take some time depending on how complex your object is).

This Inkscape Add-in is also worth a shot.

If you have trouble getting anything to show up, on the menu bar go to File > Examples > Old > example007.scad.

Convexity is a measure of the number of times a straight line could pass through an edge in your drawing (during a ray trace).

MTU computer use): import(file='\\\home\My Pictures\filename.dxf', convexity=3) This is easily acheived by dragging the file from the file explorer into the editor window of OpenSCAD.

Use the import command in the directory you saved it in.

Either save the file into your OpenSCAD directory or move it after you save it.

Then click the 'Make selected segments lines' button - see screenshot (if you can not see the buttons click F2.).

If you want a high resolution (curved lines) then click the far left button 'insert new nodes into selected segments' (do this as many times as you like 2 or 3 times gets pretty smooth curves on most images.

Select every node - go to Edit -> Select all or Ctrl+A.

(if you drew it Path-> Object to path or click Shift+Ctrl+C).

If it is a found image go to Path -> Trace bitmap - shift+Alt+B.

Convert it to a path (if it worked you should see a bunch of grey squares).

Get a 2D image and open it in Inkscape (or draw it in Inkscape).

This option is much more likely to successfully import your drawing and allow you to recognize faces, but may not result in dimensionally accurate or 3D printable STLs (it takes some practice, but it is possible).Ĭonvert Image to Vector Graphics Blender - A more flexible 3D design (not CAD) modeling software.
