Measurements at the bottom of the screen after selecting an object,
What does it mean. 10000 ln3
That’s the volume of the model, in cubic inches.
When you double tap the object you get the Volume (in3) and when you click on a face you get the area (in2).
Tapping sketch or face gives you the area. Selecting a 3D object gives the volume. By double tapping, you are selecting the 3D object. I generally use the object folders to select the items I want volume for.
And of course selecting only an edge gives you the length of the edge.
