Making a Sketch Active for Editing
To save a file, you need to exit the sketch mode. However, if you want to make changes to the saved sketches, you need to make the sketch active for editing.,
Let’s see how we can make the sketch active.
Identify the sketch1 in the model browser bar to the left of the Autodesk Inventor Screen, see below. Now right-click and select edit sketch or double click the browser sketch1 icon (if you are editing the first sketch in Inventor)
Note: In case you need to rename the sketch1 to a name that you wish, click on the sketch1 and again click and this allows you to rename the sketch1
