I am trying to create a simple wire, with a length of 80, and a thickness of only .017 (Blender units). To give the wire some droop between the two ends, I created a simple parabola, using a bezier curve. I then wanted to use a low-poly bezier circle as the bevel object. For some reason though, the bevel comes out way larger than the circle.
Here are a couple screen shots, that show the objects and all of the settings. In this first image, the circle is selected, to show all of its settings:
In the second image, the bezier path has been selected, and the circle has been chosen as the bevel object.
But, as can be seen, the resulting bevel is over 10 times the size of the circle (the dark area is the open mouth of the resulting tube). Does anyone know why this is happening? The tube should be the same width as the circle.
