I can get my harness to route produce the 3D model of my harness. See below. Blue arrows are labels and Red is heat shrink.

Every time I try to flatten my harness, to try and create a cable diagram with part callouts, one end of my cable fans out a great deal (see Red Circle). I want both ends to look like the the blue circle.

Also while flattening the cable for the cable diagram drawing it now moves the heat shrink nowhere near the connector, not giving a accurate depiction of what the cable should look like.

So first issue is why does this one end always fan out this way?
