I want to delete part of an object like in the picture below. But since I will transfer it to another 3D application, I must not change the number of vertex or face.
I can slide the selected edges to the next edge one by one with "Edit Mode" and "Edge Slide" and make the part I want to delete invisible, but this process is very troublesome. How can I make this process easier?
the selected edges are the parts I want to delete
the part I made invisible by shifting the selected edges to the left without deleting any edge or vertex
