In this previous post,
“Scale individual axis without locking the other axis, please”
it is indicated that preform would be too complicated to use if this function would be added … (I dream?)
It is also indicated that it is enough to modify the scale in a CAD drawing program … yes if you have done the drawing yourself, but that must print files already in STL format I don’t want to complicate my life with another intermediate program !!!
FYI: with CURA that I use with my ultimaker 3, this scale function has been around for a long time
Thanks
