no 2018, pretty poor that sketchups own "fix model" is what broke the file to a point where its completely gone... plus a driver update is as good of an answer and switching it off and on again, its the file not the computer thats the problem. broken file

Just a suggestion, instead of doing the "rotate it many times around that point" manual way. Try D,burs Align plugin:DBUR_Align_v1.0.1_5.rbz it's a lot faster. Find at extension warehouse here: http://extensions.sketchup.com/en/content/align I used it to make this sample: [image: dburalignsample.jpg] Just had to right click on the bolt plate and select Align component/group and align the red &green axis on the part you want the bolts on and it would copy and rotate it into place.
