Your axis 3D model is likely broken due to mesh errors, incompatible file formats, or incorrect axis setup in your 3D software.
Mesh issues (like non-manifold edges/holes or flipped normals) disrupt the model’s structure. Lossy file formats (e.g., STL without axis data) or misaligning the model’s local axis with the software’s global axis can also cause display or functionality problems.
For mesh errors, use your software’s built-in repair tools (e.g., Blender’s “Make Manifold” or Fusion 360’s “Heal Mesh”). For file issues, re-export the model using lossless formats like FBX or OBJ that include all associated data.
