i am trying to model a car rim in blender. i modelled it with using mirror modifier and array. When creating some edge loops for sharp edges it is not appearing same on both sides of the mirror modifier instead Edge loop automatically get snaps to nearest vertex at the end of loop. I tried reducing the distance in array modifier, but its not helping. and also blender crashes when i do so. pls help. Screenshot attached for your reference
Both the mirror and array modifiers have settings to automatically merge vertices from the generated parts with the real vertices. When adding or adjusting vertices near the edge you sometimes need to disable these options for a while. Sometimes you also need to adjust the merge limit so that you don't get excessive merges happening.
