Using the “undo” command, either by ctl-Z or clicking the undo button, still causes Sketchup to slow waaaaaay down. Even with relatively small models (less than 1MB in size). This was not a problem in 2016 or earlier, but still hasn’t been fixed in 2018.
Has anybody discovered a workaround for this that does not require disabling undo or closing and re-opening SKP every three or so uses of the undo command? I’ve searched the archives for fixes to this, and that seems to be the only suggestions so far.
