How do i find the inside volume of this part? I tried intersect but got only the outside body.
You could Surface>Offset distance zero the inside surfaces, Planar Surface cap the ends and Knit.
I recommend that you fully define your sketches.
Thanks J. Mather. So, I have to use surface features to fix it? Where is the issue with the model? Is it because it is open both sides?
Are you a student?
Do you understand why some sketch lines are blue and others are black?
What do you observe if you click and drag blue sketch elements?
I did not quite understand your comment. I was wondering about the issue with the model to have intersect. I have done intersect for other models such as a cylinder with one closed end and it was OK.
