How to convert COLLADA (DAE) to OBJ

خطوة بخطوة

1. 1Blender: File → Import → Collada (.dae), then File → Export → Wavefront (.obj).
2. 2In the export panel, tick 'Triangulate Faces' if the target application dislikes n-gons, and choose whether to write the .mtl material file.
3. 3If the model comes from SketchUp Free, apply object transforms after import (Object → Apply → All Transforms) so the OBJ is not offset from the origin.
4. 4Check the up axis: COLLADA declares its own, and OBJ does not. Set Y-up or Z-up on export to match your target.
5. 5Keep the .mtl and textures with the .obj when handing it over.

أمور يجب الحذر منها

• Animation and skinning are lost — OBJ is a static geometry format.
• Double-sided SketchUp faces often import with inconsistent normals; recalculate them in Blender before exporting.
• MeshLab and Assimp's command-line tool are alternatives if you prefer not to open Blender.
