Hello to all,

I want to display two curves from six InterpolatingFunctions

{r1x[t], r1y[t], r1z[t], r2x[t], r2y[t], r2z[t]}

produced with NDSolve. The documentation describes the  usage of
ParametricPlot3D for displaying one curve:

ParametricPlot3D[{fx,fy,fz},{t,tmin,tmax}]

and this works fine for me:

ParametricPlot3D[Evaluate[{r1x[t],r1y[t],r1z[t]}/.%],{t,0,dt}]

For plotting several objects together,  the documentation says:

ParametricPlot3D[{{fx,fy,fz},{gx,gy,gz},...},...]

but

ParametricPlot3D[
{Evaluate[{r1x[t],r1y[t],r1z[t]}/.%],
Evaluate[{r2x[t],r2y[t],r2z[t]}/.%],{t,0,dt}},{t,0,dt}]

doesn't work at all. I tried to vary this expression in many (also
stupid) ways, without any result. What's wrong with it?

Thanks a lot,

V o l k e r
