graphics - How to export a 3D circle as a single piece PDF vectorial object?

I need to export a circle drawn in 3D with a specific point of view to a PDF file. This is easy to do. However, the exported circle is made of tons of non-connected small bits. I need the whole circle to be a single piece in vectorial form. How can we do this ? Take note that I also need the three axes to be exported too (they are not cutted into small parts, which is what I want).

Here's the code itself :

ParametricPlot3D[
    {Cos[p], Sin[p], 0}, {p, 0, 2 Pi},
    PlotStyle -> {Directive[AbsoluteThickness[1], GrayLevel[0.5]]},
    PlotPoints -> 100,
    PlotRange -> {{-1.5, 1.5}, {-1.5, 1.5}, {-0.5, 0.5}},
    Boxed -> False,

    Axes -> True,
    Ticks -> None,
    AxesStyle -> Directive[GrayLevel[0.5], Dashed],
    AxesOrigin -> {0, 0, 0},
    ImageSize -> {750, 750},
    ViewAngle -> 25 Pi/180,
    ViewPoint -> {1, 1, 1},
    SphericalRegion -> True,
    Method -> {"RotationControl" -> "Globe"}
    ]

Exporting to a PNG or JPG file is not an option here. I need the vectorial form of the curve, as a single piece (I'll also have to do the same with another curve, much more complicated than a simple circle).

functions - Get leading series expansion term?

Given a function f[x] , I would like to have a function leadingSeries that returns just the leading term in the series around x=0 . For example: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x)] x and leadingSeries[(1/x + 2 + (1 - 1/x^3)/4)/(4 + x)] -(1/(16 x^3)) Is there such a function in Mathematica? Or maybe one can implement it efficiently? EDIT I finally went with the following implementation, based on Carl Woll 's answer: lds[ex_,x_]:=( (ex/.x->(x+O[x]^2))/.SeriesData[U_,Z_,L_List,Mi_,Ma_,De_]:>SeriesData[U,Z,{L[[1]]},Mi,Mi+1,De]//Quiet//Normal) The advantage is, that this one also properly works with functions whose leading term is a constant: lds[Exp[x],x] 1 Answer Update 1 Updated to eliminate SeriesData and to not return additional terms Perhaps you could use: leadingSeries[expr_, x_] := Normal[expr /. x->(x+O[x]^2) /. a_List :> Take[a, 1]] Then for your examples: leadingSeries[(1/x + 2)/(4 + 1/x^2 + x), x] leadingSeries[Exp[x], x] leadingSeries[(1/x + 2 + (1 - 1/x...

front end - keyboard shortcut to invoke Insert new matrix

I frequently need to type in some matrices, and the menu command Insert > Table/Matrix > New... allows matrices with lines drawn between columns and rows, which is very helpful. I would like to make a keyboard shortcut for it, but cannot find the relevant frontend token command (4209405) for it. Since the FullForm[] and InputForm[] of matrices with lines drawn between rows and columns is the same as those without lines, it's hard to do this via 3rd party system-wide text expanders (e.g. autohotkey or atext on mac). How does one assign a keyboard shortcut for the menu item Insert > Table/Matrix > New... , preferably using only mathematica? Thanks! Answer In the MenuSetup.tr (for linux located in the $InstallationDirectory/SystemFiles/FrontEnd/TextResources/X/ directory), I changed the line MenuItem["&New...", "CreateGridBoxDialog"] to read MenuItem["&New...", "CreateGridBoxDialog", MenuKey["m", Modifiers-...
