<p>I can already see several other ways you might want to define a trapezohedron such as specifying the angle of the "kite" sides or fixed distance between the top and bottom apex points instead of a vertical offset value for the points as I'm doing now.</p>
<p>Not sure how much more I want to play with this but the results can be very interesting.</p>

<p>No need of Grasshopper to make your first element. You can do them with Rhino. If you want them paramatric why not, but it is best that you bring a definition of what you want.</p>

<p>For the second image did you looke at that ?</p>

<p>Well ...</p>
<p>... I would suggest (<strong>based on your 2nd sketch</strong>) this approach.</p>
<p>See notes (especially with regard the pathetic offset thingy).</p>
<p>Used some small C# for optionally <strong>transposing</strong> the target surface (but that's the 1% of the definition that's carried over 99% by native GH components).</p>
<p>This approach is purely indicative mind</p>
