3D Printing - STL and File Preparation

ABecause duplicate vertices can cause holes and incorrect normal calculations

BBecause removing duplicates creates non-manifold edges

CBecause fixing holes first removes duplicate vertices automatically

DBecause inverted normals fix duplicate vertices

Step-by-Step Solution

Solution:

Step 1: Understand the effect of duplicate vertices
Duplicate vertices can cause gaps (holes) and confuse normal direction calculations.
Step 2: Importance of removing duplicates first
Removing duplicates stabilizes mesh structure, making hole filling and normal fixing accurate.
Final Answer:
Because duplicate vertices can cause holes and incorrect normal calculations -> Option A
Quick Check:
Remove duplicates first to avoid holes and normal errors [OK]

Quick Trick: Remove duplicates before holes and normals [OK]
