When I'm working in an assembly the display will randomly flash ghost parts in the foreground. Sometimes it happens when I'm in section view, sometimes not. I find that section view has it's fair amount of bugs that parts will just randomly disappear and you have to choose manual rebuild.
Don't forget you can manage a project well; if you have good file management and have something that can be understood by another person it's more valuable work. Sometimes I get so annoyed with the correct steps to fix a design goal that I just do a work around that leaves a lot of extra trash that won't modify the parts intuitively.
I'm a little miffed; I'm not suppose to share work. Here I was excited to utilize the online community but now I have to worry about market sharks preying on the politeness of chit chat to snatch some ideas.
