Hi Pranav, I could not reproduce this behavior. Are you sure you did not do a small Z-rotation after tiling? That might explain the appearance. I.e. first the models are laid out horizontally but then the whole view is rotated slightly clockwise. I can't distinguish that visually from a stepped layout since the rotation is small.

Try untiling (undo) and retiling and making sure not to rotate anything afterward. Or, if tiling does give a tilted row, although I can't reproduce it, maybe you could just Z-rotate the whole view slightly counterclockwise after tiling. Z-rotation is done with the same mousemode as XY rotation except with cursor in the periphery of the graphics window (the non-central area).

If you have an example for which you are willing to share data and where tiling definitely fails to lay out the row horizontally, you can use menu: Help... Report a Bug and attach the data needed to reproduce it, and include a short description.

Hi, I want to create an image of multiple volumes that are tiled horizontally. However, when I run the command "tile columns 6" the volumes get arranged in a step-like manner (attached image).

As I understood it, if you wanted to change the orientations, the way to do it is to undo a previous tile so that everything is superimposed again, then change orientation, then use tile again.

I don't think repeatedly using "tile" from a previously tiled state was intended.

Hi Pranav,

I have seen similar bad layout from the tile command. If I open 3 copies of a model the tile them it works, then rotate just one and try to tile several times and it gives all kinds of weird wrong positions.

open 1a0m ; open 1a0m ; open 1a0m tile turn y 140 model #1 tile tile

I've made a bug report for this and hope to fix it soon.
