Plotting a Sphericon and Bipyramid with 100 faces
I would like to plot a convex polyhedron with 100 faces, which could be used as a die. My first attempt was asking for Conway's Hecatohedron. Unfortunately, it can not be used as a die.
Now, there ar …

Plotting 3D Vector Field in one plane
I want to plot a vector field F={Fx, Fy, Fz}. However, I only want to plot it in one plane (say, z=0).
When I use VectorPlot3D[{Fx, Fy, Fz}, {x, -1, 1}, {y, -1, 1}, {z, 0, x}], and x=0, I get

Graphics3D from Mathematica to SolidWorks (for 3D-printing)
I have an 3D Graphic generated with Mathematica's Graphics3D, and want to use it later in SolidWorks. SolidWorks files are usually *.stp, *.step, *.stl extentions. … edit:
Just for info - my 3D Graphics (from here) is:
Graphics3D[{GraphicsComplex[
Join[{Cos[#], Sin[#], 0} & /@ Range[0, Pi, Pi/(25)], {{0, 0, 1}}],
