So I've been working with your large alignment, trying to rework spiral alyouts, and I've come across a small amount of error in the values in your LandXML.
Code: Select all
<Spiral length="375." radiusEnd="1500." radiusStart="INF" rot="ccw" spiType="clothoid" theta="7.161972439135" totalY="15.607570051337" totalX="374.414486202449" tanLong="250.204919632086" tanShort="125.186311833623">
<Start>4271523.619686000049 507067.709483999992</Start>
<PI>4271690.523937826976 507254.110858806758</PI>
<End>4271785.008000442758 507336.235000094923</End>
</Spiral>
I dont know what is causing this but I think we must protect the coordinates. If we dont, that issue effect other alignment item coordinates too. If issue repeat itself more than one time, the end station coordinates deflection will increase.Joel_graff wrote: ↑Thu Jul 18, 2019 2:18 pmdo we save the coordinate values and recalculate the curve attributes, or do the reverse?
That was my feeling on the matter as well.HakanSeven12 wrote: ↑Thu Jul 18, 2019 2:57 pmI dont know what is causing this but I think we must protect the coordinates.

Maybe you can add a warning and show recalculated and old paramaters.
Ok, so as I'm sorting out what really matters here, the number one coordinate that must be preserved is the PI.HakanSeven12 wrote: ↑Mon Jul 22, 2019 10:16 pmMaybe you can add a warning and show recalculated and old paramaters.
