Bug in Parabola by Focus and Diretrix?


Hello!

Please, see the movie available at

http://www.professores.uff.br/hjbortol/tmp/parabola-bug.gif

When the point L is moved, depending on its position, the parabola disappears.

The CDY file is here:

By the way, it seems the "Attach file" in this forum is not working.

Thanks in advance, Humberto.

My analysis is that this problem seems to appear when the objects are not near the origin. It seems to be related to the problem "H#183 display of degenerate conics" which I reported last year. It still exists in build 1077.

That's indeed a bug, I downloaded the .cdy and we will fix it some day.
