Zoom Limited

Hi I’m new to Blender and have been working through some tutorials on line. Things are going well for the most part. However I’ve gotten in a stuck mode where I’m limited to how far I can zoom into the model/object I’ve been working on. I see no setting for this. Not sure how I got into or how to get out.
Anyone know how this happened and how to get out of it?
Thanks in advance.

Try using the View -> Frame Selected (obviously select something of interest first). As you pan around the scene the view focus might get too near the camera and interfere with zooming. That command resets view focus and lets you zoom again.
