Hello,

I am modeling mechanical components in Mathematica and there are  
places, (particularly where these must fit together), where the  
geometry of a piece must change.

Can I, (or how would I), instruct Mathematica's ParametricPlot and  
ParametricPlot3D symbols to include specific values within the  
parameter set, (to be located at the geometric boundaries)?

(e.g.) If X is a parameter being swept between -1 and 1, how would i  
instruct Mathematica to include the fixed values 0.522 and 0.824?

Further, if the precise location of a boundary is only known after  
parameter X is given; is there a way (based on that information) to  
instruct ParametricPlot3D to include a specific value within the range  
of the second parameter, Y?
