Lesson 02 - First Launch
By the end of this lesson you will:
- Recognize the main FreeCAD window.
- Create a new document.
- Understand that a document is the file that holds your model.
Step 1 - Create a new document
Click File -> New, or use the new document button if it is visible.


Why?A FreeCAD document is the container for your model. Before you create geometry, you need a document to hold it.
Step 2 - Look at the model tree
Find the model tree, usually on the left side of the screen. Your new document appears there.

NoticeThe model tree will become very important. It shows the history and structure of your model.
Summary
You opened FreeCAD and created your first document. Next, we will identify the interface areas you will use most often.
