There is a list of some bugs I found in Rhino 5.
By using the command “Text” and settings text alignment to the right, I get this result. See the Anchor point on the image below which is not located at the extreme right of the text. The font used is “Gautami”, but many other font are giving me the same result (not all fonts by the way).
When using the command “BlockEdit” over a block instance that contains geometries with mappings, All mapping positions are resetted to [0,0,0].
In the texture mapping properties, the button “1,1,1”, set the size of the mapping to 1,1,1. But it also "center the mapping Inside its previous size. I think this button should ONLY modify the size and keep the mapping origin at the same place.
Also, I would to have a new “button” to size the map in relation to the texture ratio.
