04 Selection tools on the ribbon
To chamfer off these newly raised rims we first need to select the appropriate edges. This can be a bit laborious when there are many small edges to pick one by one. Fortunately there are some very useful selection tools in the Ribbon menu to help with this. Here you will find a tab named Modify Selection. Select two edges lying opposite each other on a loop, change the Dot Gap to 0 and click on Dot Loop Cylinder and the whole loop will be selected in one go. Once selected choose Chamfer in the Editpoly modifier and choose an Amount value with a single Segment.
