How to add a live edge (uncut wood) in Featurescript

sven_kautlenbach

Hi!

I am a programmer first, but I have had some experience with SolidWorks before and now years later I have started to use Onshape to virtually build my ideas. One of the projects is a speakerbox. I have managed to build and assemble it with the built in features, but now I took a step further to simply parametrize it with some variables (like litres, wood thickness, max height).
To start with the little things first I have managed to create one rectangular side with code. It has some options like if this side would be the supporting one (automatically adds the thickness to the length) in the edge. For the sake of the visualization I would like to add a live edge to the sketch via boolean parameter. When manually doing it, I use spline tool to randomize the curvature.



These are the visuals built manually to get the general idea


I know that here should be some face to be queried and upon that there would be some spline sketch that then could be extruded upon that face/edge.
The spline curvature could be generated using some pseudo random function like proposed here - https://forum.onshape.com/discussion/comment/18945

I'm not 100% sure what you mean by a "live edge" -- if you just want to display something while the feature is being edited, take a look at https://cad.onshape.com/FsDoc/library.html#module-debug.fs
If you want to add an edge to a sketch that you can then drag, FeatureScript cannot do that.

By "Live edge" I assume you mean the uncut edge of a tree. Here's an FS feature adds a sketch spline like you suggest:

You utilize the PRNG Ilya wrote (that you linked above) if you change the values of the splineOffsets variable.

Let us know if you have more questions!
