So far I've found the instructional videos rather helpful to understand what I'm getting myself into.
However after installing the trial to teach myself, I've immediately run into issues where I can't move a simple "room" created by the rectangular wall tool. Multiple videos demonstrate the very intuitive process of highlighting with the selection marquee tool then dragging what has been selected. Yet when I attempt to do this, all it does is start another marquee selection from inside the "room" previously selected prior to my attempt to click to start dragging it.
I had hoped it was a class/layer/permissions/lock issue, however this is a brand new install and I hadn't modified any of those, as well as having checked over those (to the best of my knowledge) for conflict after running into this issue. I felt that modelling my house would be a great exercise for what seems to be rather intuitive software, however after a full day of re-watching videos along with general exploration of the software, I feel like an idiot for still not being able to move a simple 2D rectangle. At this point my need to know has surpassed my embarrassment at my ignorance of a most basic function. Any help is appreciated.
