I had tried many ways to use elements/objects to create a cylinder with top and bottom. The result always shows the elements do not display on the circle surface area. [image] [image]

When using THREE.Cylindrical you effectively work with cylindrical coordinates which can’t be used to compute points for the cylinder’s caps. I suggest you study how CylinderGeometry generates its caps and use a similar approach for your app.
