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 Ve …

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}}], { {#, Rotate[Rotate[#, 180 °, {0, 0, 1}] …
