Hi guys,
Gotta start out saying sorry i’m new here and to zbrush and i have a lot of questions that keep bugging me as i started working with the software. I havent had 3d experience before, i come from a 2d art backgroundand I really wanted to get into modeling.
Wanted to make an art/question thead but couldnt find a section for personal threads 
For now my main question is when I go into edit mode(T) i can never get out of it, it always gets stuck on it and i have to reset
When saving a file via quicksave when i close it and open it again i find it never actually saves it, the save state is from an hour ago… a bug?
When saving a project and opening it up again it opens it as a flat image… did I save it a wrong way? What’s the best way to save a project?
What’s the easiest way when adding blobs shapes and squares to merge them with the main shape so i can manipulate them as one object?
I was watching some lessons on modeling and the teacher advised that he’s stepping up a subdivision level… how do you do that? would that simply mean that he’s breaking the object up into more polygons? Or that he’s just making the brush smaller…
with masks is there a lasso type mask where i can select idk an eyeball shape only and edit that? what are the shortcuts for breaking off the selection i mask (for editing) so i can edit it and then when done getting back to the full shape?
I really appreciate any answers to any of my questions 
And if it’s ok i’d like to post some of my molds for critique if that’s ok or if there’s a personal art thread section somewhere here that’d be great too!
Thanks so much!
