Possible bug: Circle command
Answered
Hi,
There appears to be a bug in the Circle command, as follows:
The following sequence works:
A=(0,0)
circle[A,2]
It draws a circle with radius 2 centered on X=0, Y=0 as expected.
Now I want to draw the same circle but at some distance above the XY plane, i.e. it must be displaced in the +Z direction. Try:
B=(0,0,1)
circle[B,2]
...failure. 'Sorry, something went wrong. Please check your input'.
I am using 4.9.17.0 of 23 January 2012.

The circlecommand in 3D is different from from that in 2D!!!
A point and a radius is not enough to create a explicit circle:
Have a look at the realeasenotes http://wiki.geogebra.org/en...

Hi, there is a lot of circles in the space with center B and radium 2 : one for each plane which contains B.
You have to add a parameter to choice the plane you want to use, using an orthogonal line of this plane. For eg, if the plane is parallel to the XOY plane, use :
Circle[B, 2, zAxis3D]

Hi all,
Michel's tip works! :D
B=(0,0,1)
circle[B,2,zAxis3D]
does indeed produce a circle of radius 2 offset in Z by 1 unit from the XY plane.
Thank you,
Swulf
