I am working on a wheel design and I want to make the line grain radiate from the center point of the wheels. (Like rays of the sun instead of the typical brush finish that is concentric.) I am trying to use spherical mapping, but Solidworks seems to locate the sphere in a random spot nowhere near the center of the part. I can rotate and resize the sphere, but how do i relocate it to the center of the wheel? Clicking on the sphere just makes it rotate.
