Rotating functions
The first way I found to export to an STL file is rotating a function on the x axis.[br][br]In this applet a building was modeled. We can model any object of our interest and rotate 360° it in the x axis to create a solid of revolution. [br][br]In this applet the building I used is: 30 St Mary Axe (The Gherkin) [url=https://en.wikipedia.org/wiki/30_St_Mary_Axe]https://en.wikipedia.org/wiki/30_St_Mary_Axe[/url]
This kind of activities allow us to work:[br][br][list][*]Functions[/*][*]Modelling[/*][*]Algebra[/*][*]Solids of revolution[/*][*]Integrals (volumes of revolution)[/*][/list]
The problem I found is that when I tried to export this to STL I could only export the axis, the trace of the functions are not exported in STL because a trace has zero thickens.[br]
Solution:
This problem was solved using the command [b]Surface( , <Angle> )[br][/b][br]Getting this result:[br][br]
This is how the STL looks like:
Axes can also be left out. [br][br]You can try this command in the applet showed before.
