Mirroring

[coldcomfort]

I was trying to figure out the best positioning for a house, in respect to how the sun rises and downs.
We can rotate the compass but would be useful also being able to flip it (inside out / west becoming east). The cardinal points on the compass should remain constant but the symmetry of the plan should be changed accordingly with the axis (N-S).



Or, as a more straight forward approach, would be useful to be able to set an axis and copy and mirror selected structures in the 2D plan (also the whole plan at once, on all levels)

You can already mirror your house with the advanced editing plugin, when you enter a negative value as width in the Resize dialog.
I would be curious to know if it still works with levels too (you'll probably have to change the items level by level).

I see. It works fine with individual levels but produces some twisting/crossover on "related" levels. I'm trying to figure out if this can be avoided in my case.
