Graphics, Figures & Tables ⇒ Figure repeatability and relative positioning within a float

[ZeV]

Hello everyone. I am not new to LaTeX, but I am new to tikz. I am playing around with it today, in anticipation of a lab report on some semiconductor experiments I am running, and have made a simple 3D representation of a GaAs unit cell in tikz. However, I am uncertain about how to:

• Rotate/align the figure in three dimensions
• Position the picture relative another figure/picture in the same float

Ideally I intend to position the unit cell at given coordinates within my figure, and then - within the same figure (or at least float) make a visualization of my GaAs substrate

You have done a great job so far. The Zinc blende structure of GaAs is clearly to see. But since pgf/tikZ has only very limited capabilities regarding 3D, you should take I look at the tikZ-3dplot package. I think it will answer all your questions and fix all issues.


Best regards and welcome to the board

Whoa! That was easy! Thank you VERY much!
