Hi,

I am also having the same problem. I have been trying to open files and it distorts my geometry. When I was looking for answers I came a cross that this is a problem caused by having multiple authors or something similar. I do not remember the exact phrase there. Still all the other forums and websites were also telling to recreate the work from scratch. I have done so several times and ended up having distortion again and again. After doing the same work dozens of times, I started to get a bit frustrated. Is there a proper reason for the distortion problem? I will be doing the work from scratch again but still what should I do to prevent this issue of distortion?
