I NEED HELP CONSTRUCTING THESE COLUMNS ON SOLIDWORKS!!!! I WILL UPVOTE!!

Problem $1(25$ points$).$ Consider five $($one$-$by$-$one$)$ columns of lengths $1\mathrm{.}0m,3\mathrm{.}25m,5\mathrm{.}5m,7\mathrm{.}75m$ and $10\mathrm{.}0$ m $.$ All these columns are fixed at the bottom and free at the top. For each column, the cross section is circular with a diameter of $200$ mm $,$ and the material is alloy steel. Perform a buckling analysis for each column using SolidWorks. Show the first buckled mode shape for each column, and report the first critical load $(P_{cr}=$ Applied Compressive Load $$ Buckling Factor of Safety for Mode $1)$ for each column $($in a table$).$ You are free to choose any value for the applied compressive load using your judgement $($to be applied at the top of the columns$)$; I recommend choosing around $1,500kN.$ Next, using the so$-$obtained five data points $($ie$.,$ for five columns$),$ show the scatter plot $($a spreadsheet can be used for this$)$ of the critical unit load $(=\frac{P_{rr}}{A},$ where $A$ is the area of the cross section$)$ vs$.$ slenderness ratio $(=\frac{l}{k},$ where $l$ is the length of the column, $k=\sqrt[\phantom{2}]{\frac{\text{I}}{A}}$ is the radius of gyration, $I=\frac{d^4}{64}$ is the moment of inertia of the cross section about the neutral axis, and $d$ is the diameter of the cross section$)$; this plot should look like the figure shown below.
