Export SVGs from Fusion 360#

About this document#

This document intends for

  • Those who want to export sketches containing splines(e.g. spur gears) from Fusion 360
  • and want to open the files with Inkscape for lasercutting

Those who afford Adobe Illustrator, don’t bother reading.

Two measures are introdueced here, one is using a Fusion 360 Add-in, Shaper Utilities, and the other is a Java library, Kabeja.

Introduction#

Fusion 360 has an Add-in, SpurGear, which is able to create the spur gear(平歯車) easily.

Opening an exported DXF file in Inkscape causes an issue. The profiles of teeth are missing.
According to this thread, the problem is Inkscape can’t handle splines that are higher than degree 3, and splines of the sketch in Fusion 360 are degree of 5.

Shaper Utilities#

More detailed documentation is here

Downlaod Shaper Utilities and install it.

After installing it, you can see Shaper logo on Tools tab.

Export an SVG file#

Assume that you created spur gears and want to export sketches as vector file to lasercut.

Click Shaper logo

Check Advanced checkbox.

Thne, select Solid Bodies Layout

Select bodies lying on the X-Y plane to export and press OK button.

Save it as an SVG file.

Open the file with Inkscape

Object > Fill and Stroke dialog, Set Stroke Paint color Red.

and set Fill “No Paint”.

Also set stroke width at least “0.001 mm” so that Trotec’s Job Control recognizes the strokes as the cuttinng line, but which makes lines invisible on your screen. Job Control will recognize the width of “0.05 mm” as the cutting line, but I’m not sure whether it might cause any problem.

If you are using Inkscape 1.0 and later, selecting View > Display Mode > Visible Hairlines makes strokes visible again.

Kabeja#

Download Kabeja from SrouceForge.

Start Kabeja and open an DXF file exported from Fusion 360.

Click “Inkscape” button and Kabeja will create an SVG file.

Open the exported SVG file and you will see the profiles of gears properly.
Set stroke color and width before lasercutting.
