@acer It worked, however, upon further inspection I found this circle attached to the solid I can't seem to remove. I tried adjusting the view and domain. However, this removes a strip from the solid. How can I fix this? Also, is there a way to make the image larger? I tried removing the constraint, but then it shows an image that is not scaled well. Also, I am looking to change the size of the image only, not the plot window.
VolumeOfRevolution(2*x^2 + 1, x = 0 .. 1, volumeoptions = [color = ["Niagara 1"], transparency = 0.5], orientation = [270, 90, 0], view = [-1 .. 1, -3 .. 3, -3 .. 3], labels = [z, x, y], output = plot, axis = vertical, scaling = constrained)
