I have created a tool based in two points that generate a 3D Locus.

The output selected include this two points and the generate Locus and when i use the tool, the louca doesn't appear.

I'm using the latest version of GeoGebra downloads manually from the site.

I have created a tool named "Tool1" that creates a locus point, the point generator of the locus but the locus curve does not appear.

Sometimes even the original locus (not created by the tool) disappear for somes choose that we made for the zoom.

Any ideia how to solve this problem?

Can you parameterise this and use Curve() instead?

ImplicitCurve(1 / 16 ((a x + 2 / 3 y - (-2 / 17 x + 1 / 17 y - 2 / 17))⁴ + ((-2 / 3 x + 2 / 3 y)² - 4 (1 / 3 x² + 2 / 3 y² - 1 / 3) - ((-2 / 17 x + 1 / 17 y - 2 / 17)² - 4 (1 / 17 x² + 1 / 17 y² + 2 / 17 x - 3 / 17)))² - 2(-2 / 3 x + 2 / 3 y - (-2 / 17 x + 1 / 17 y - 2 / 17))² ((-2 / 3 x + 2 / 3 y)² - 4 (1 / 3 x² + 2 / 3 y² - 1 / 3) + (-2 / 17 x + 1 / 17 y - 2 / 17)² - 4 (1 / 17 x² + 1 / 17 y² + 2 / 17 x - 3 / 17))))

CAS can't solve this 4th degree equation in order to x or y than i can't parameterise this curve

Sorry, in that case I can't think of a way to get it to work

how come GeoGebra locus created by the tool doesn't show the locus?

The locus is originally created by GeoGebra
