Feature Script for Woodwork Biscuit Joints

Question

I am trying to design some Woodwork projects for our Makerspace using Biscuit Joints, and found an Onshape script.  I seem to have a challenge getting it to work for me.  When I put the connection on the opposite end, they don't line up. Anyone using this script that can answer my question?

Please post a link to your model so we can see where the problem lies.

Here is the link to another model, as I regrouped on the first one.  It appears to put one end measured for the top, and the other measured from the bottom.  In the example - I used the same part on both ends, but in this one I used separate parts (1 & 2).  You can see they match, but are at different offsets.

Here is the link to a test document I did, and you can see the elevation of the joints is different on each end.  It showed up on the original, because I used the same part on both ends.  I gave up on that one, and did a work around. But here is another model.  It would be nice to change the biscuit size for different applications.  The idea is great!!

@patrick_shea The issue is in the featurescript for the biscuit joint. The opExtrude they use is always normal to the sketch plane which is related to the plane origin of the edge between the two parts to be joined and doesn't allow you to reverse the direction or set a symmetric parameter to the biscuits.

opExtrude(context, id + "extrude1", {
                "entities" : qCreatedBy(id + "Biscuit_Joint_Sketch", EntityType.FACE),
                "direction" :SketchPlane.normal,
                "endBound" : BoundingType.BLIND,
                "endDepth" : 2e-3*meter

        });

@martin_laabs Could you please update your biscuit joint featurescript to BoundingType.SYMMETRIC to help this gentleman with his symmetrical biscuit issue.
