I have just come back into hifi after being away while waiting for things to improve. I have heard that things are better from an email I received but all told things appear to be the same as before.
I found that my domain server had to be updated to Ubuntu 15.04 but I had to search all over to find enough bits and pieces of information to get the servers to compile.
After I got my domain running I inserted a model that I had used before and I cannot figure out how to rotate it into position so I stopped interface and restarted. Now the model is not visible but I see the green box.
The documentation page for hifi looks substantially the same as before with the same info which is now even more out of date and scattered.
At this point I gave up on hifi once again. I’ll come back 'round again later to see if there is any new hope.
