You can get the 3D graph with the Maxima plugin

Hi. Just another way, in addition to the solutions offered by Overlord and Pompelmo, using the ability of XYPlot plugin for plot parametric curves, as is explained here.

Parametric ability is a good addition.
I wish 2D-Plot has this feature too.
I also would like animation for XY-Plot.

The Maxima plugin provides plotting functions, among them parametric plots. For details look for "kraska smath handbuch".

Note that there seems to be a png export glitch. The region t:=25 is disabled in the sheet but not grayed out in the export (image below). The parameter variable obviously must be undefined, otherwise the x and y expressions are just numbers.

I have no recollection of Parametric Engineering project(s).
Whatever, this document advances your Parametric Journey.
Ultimately, export the project as a standard data table for publishing.
... offered up to the derivatives of the piece-wise project.
Comments, more help ... Welcome.
Cheers ... Jean.
