Can't zoom where I want in scene I'm new to Blender, so I'm stumbling around. Sometimes when I open a project, I can't zoom into what I want. I can zoom out... way outside the model (like an apartment), but when I zoom inside it, I can't zoom any further.

Sometimes I'm in the model and zooming as expected, moving around, and then I don't know if I do something wrong, but suddenly I can't zoom after rotating from some point. Sometimes it seems I zoom towards the outer perimeter of my model, and it won't go any further than that boundary... I can't zoom any further.

Sometimes, if I exit Blender and restart, then re-open the project, this behavior is reset and all is normal again. Sometimes not.

What am I likely screwing up? Thanks!
OK now that it was confirmed to fix the problem I'll make it a response.

Blender zoom works in such a way that the more you zoom in, the less each scroll zooms in (still haven't found a better way to explain it). selecting the object you want to focus on and pressing "." on the numpad recenters the object in the view and resets the zoom so that it's much easier to navigate around your object.
