topic Selection Tree items all turn grey and cannot be seen, nothing is hidden in Navisworks Forum https://forums.autodesk.com/t5/navisworks-forum/selection-tree-items-all-turn-grey-and-cannot-be-seen-nothing-is/m-p/9113611#M7502 <P>My Navisworks selection tree has gone all grey and no models can be seen. Nothing is hidden as in a previous post, and any new model appended is grey as well. All was perfectly visible before in this exact same Navisworks session. What happened and how do I resolve this?</P> Tue, 29 Oct 2019 00:54:43 GMT michael.girard 2019-10-29T00:54:43Z Selection Tree items all turn grey and cannot be seen, nothing is hidden https://forums.autodesk.com/t5/navisworks-forum/selection-tree-items-all-turn-grey-and-cannot-be-seen-nothing-is/m-p/9113611#M7502 <P>My Navisworks selection tree has gone all grey and no models can be seen.
