taper

 I am having a hard time laying out this taper. Not sure the best open road tool I should be using for this taper. I cannot get the back tangent to match the bearing that was given as a check. See Image

    There is a long-standing bug with the taper-arc tool in that it does not actually work. The taper picks a tangent line and tapers to that rather than tapering to a curved alignment. The variable offset taper tool tapers along curved alignments just fine though. I've raised this bug through an SR and even in one of the SIGs, but it does not get attention.

    In this extreme example, you can see that the 1:15 taper is correctly honoured along the tangent alignment, but not along the curved alignment:
