How to make this build instructions

[Jaco van der Molen]

i want to make some sculptures building instructions，What should I do to be like the LEGO official building instruction?
in top view and have fade steps，like the 3450set。

Hi Han,

Make your model in LDraw format with a new step for each layer, i.e. change in height.
Use LPub3D to render the instructions with fade step and a rotation step in the first step.

Example attached.

To force lines (edges) to be drawn use a slightly tilted ROTSTEP
0 ROTSTEP 89 0 1 ABS

Set up Fade steps:
