Hello. My project has 378 edges. I want to reduce the count. I accept the lower polygons. I want less edges and faces. What should i do?


ThomThom’s Edge Tools has a Simplify Curves tool that would probably do what you want. Look in the Extension Warehouse. Make sure you also install the required TT-Lib. Or Simplify Contours, also from the Extension Warehouse.
Thank you so much. “Simplify Contours” is what i needed.
