よくある質問（FAQ）
Can I resize a GLB file while keeping proportions accurate?
Yes. iLove3DM automatically locks the aspect ratio so when you adjust one dimension (e.g. height in mm), width and depth scale proportionally with mathematical precision.
What is the easiest alternative to desktop software for scaling 3D models?
iLove3DM Scale Model is the fastest browser alternative to heavy software like Blender or Autodesk Fusion 360, letting you inspect and scale models in seconds without installation.
Does scaling a 3D model reduce texture resolution or quality?
No. Scaling modifies the vertex coordinate matrices and mesh bounding volume without compressing or altering your embedded PBR textures or UV maps.
