Anyway, I worte a post about the same issue here.<br />http://plevit1.blogspot.kr/2014/12/cycloid-helen-of-geometry.html<br />You inspired me. :)<br />Thanks, Aaron.

If you click on the image that shows it i...Havard-<br /><br />If you click on the image that shows it in Elevation, and you look at the bottom right (where the profile is hosted) you can see what the issue is:<br /><br />1. WITHOUT the extra points below the end points, the profile is "bent upwards" at the outside, since the only points next to the end points are inbound, hence the spline is "bent inward facing up" at the originating endpoint. Its not truly representing vertical.<br /><br />2. Adding in the extra points "below ground" causes the spline to TRY straightening out, but it still infers from the points above, that there is a bend. So adding these points causes it to OVERcorrect. You can see the profile is now "bent down" because the very end of the spline now "bows out" at the endpoints.<br /><br />Unless im missing how to do it, i can get an ARC to snap tangent to a sliver of line that is perfectly vertical, but with a Spline Through Points i dont know of any way to achieve such a thing.<br /><br />Since (at best) this geometry will get reinterpreted from the data points, im not overly worried about it since ill have to dance with other software regardless. But, it does make it less than perfect.<br /><br />Can you email me an example of how you got it to work out correctly? Id love to post it...Aaron Mallerhttps://www.blogger.com/profile/08146075275463175361noreply@blogger.comtag:blogger.com,1999:blog-4422615611587038208.post-37292730870216226862013-03-09T01:54:13.880-05:002013-03-09T01:54:13.880-05:00Hi Aaron.

I've made this happen with additional points, but yours didn't work?<br /><br />HåvardAnonymoushttps://www.blogger.com/profile/12159886124699205759noreply@blogger.com
