I've a 3D form like below and I want to project that marker in every surface of that form including the one on the top but not the ones behind.. Anyway, I want just to know the way how projection works and if its possible
\documentclass{article}
\usepackage{tikz}
\begin{document}
\pagestyle{empty}
% The following code is generated by Sketch. I have edited it a bit
% to make it easier to read.
\begin{tikzpicture}[join=round]

\tikzstyle{ann} = [fill=white,font=\footnotesize,inner sep=1pt]
\tikzstyle{ghostfill} = [fill=white]
\tikzstyle{ghostdraw} = [draw=black!50]
% Second version of the cone

tikz-3dplotcan help with the coordinate system, but projections are something else again. – cfr Aug 21 '17 at 12:55
