For example, an image of a bunch of small balloons will work better than one big balloon.

SVG files comprised of individual small shapes will work better than SVG files comprised of larger shapes. The direction chosen in the macro is based on the center of gravity of the shape being extruded, but with long shapes this is still problematic.

Then, G-code instructions are provided to a machine controller (industrial computer) that tells the motors where to move, how fast to move, and what path to follow. This is because we have to choose a direction for the extrude process and, no matter which direction we pick, a highly curved shape will intersect itself at some point along the way. gcode file is created by a slicing program, which turns a CAD drawing into a string of code that a 3D printer can understand. Unfortunately, the solids produced from the curved sketch are often invalid. That automates this process, creates a cylinder of the appropriate size, and extrudes the curved sketch. We can also use the Curves workbench (You must install the Curves workbench via the Tools -> Addon Manager.) to map the SVG imported sketch to the surface of a cylinder.

Now you have a single sketch comprised mostly of bsplines with a lot (a lot) of degrees of freedom. You can then delete all the other sketches that were produced in the previous step. From the Sketch menu select the merge sketches tool. Now select all the different sketches and go to the Sketcher workbench. You can hide (or delete) all of the original import objects. Choose the make sketch tool, which will (if all goes well) produce multiple sketches (one from each of the objects produced during the SVG import).

Select all the objects and go to the Draft workbench. You will get a number of objects from this import.

First, create a new document, then select Import from the File menu, select your SVG file, and choose to import it as geometry (not as a drawing). Once you have the SVG file it's simple to import it into FreeCAD. You can upload your image to their server or you can copy/paste the url to the image, and then download the converted file. There is an online tool free to use that seems to work very well: The first step is to convert the image into SVG format. Any (relatively simple) image can be imported into FreeCAD and converted into a 3d object.
