Free online SKP to DAE converter

A DAE file is needed when a 3D editor, game engine, renderer, viewer, or asset library cannot open SketchUp’s native SKP format. Exporting also creates a shareable interchange copy that does not require the recipient to use SketchUp.

SKP is SketchUp’s native 3D project format, used by architects, interior designers, contractors, product designers, and 3D modelers. It can store meshes, groups, components, tags (formerly called layers), scenes, styles, materials, shadows, model units, and metadata for buildings, interiors, furniture, terrain, and construction concepts. SKP files are primarily intended for continued editing in SketchUp, and newer files may require a newer SketchUp release than the one used to open them.

What the DAE format is

DAE is the filename extension for COLLADA, an XML-based 3D interchange format. A DAE file can describe polygon meshes, transforms, object hierarchies, cameras, lights, materials, UV coordinates, and references to external image textures. It is supported by some 3D editors, rendering applications, game tools, CAD viewers, and asset-management systems.

DAE is an interchange copy, not a complete replacement for the SKP project. SketchUp styles, parametric or dynamic behavior, scenes, section settings, dimensions, guides, shadows, and construction-specific metadata generally do not transfer. COLLADA support also varies between applications, so a file that opens correctly in one program may import with missing materials or altered hierarchy in another.

Convert SKP to DAE with SketchUp

SketchUp desktop is normally the most direct and predictable method because it can export COLLADA without an intermediate format.

1. Save a backup of the original .skp file.
2. Open the model in a SketchUp desktop edition and version that provides COLLADA export.
3. Remove hidden objects that should not be delivered, purge unused materials and components where appropriate, confirm the model units, and check that texture images are available.
4. Choose File → Export → 3D Model.
5. Select COLLADA File (*.dae) as the format, specify the output filename and folder, and open the export options if they are available.
6. Enable material or texture export when offered. Use the option that preserves texture images if the destination application needs the model’s surface appearance.
7. Export the file, then open the resulting .dae in the software that will use it. Check scale, orientation, object hierarchy, materials, UV mapping, and missing textures.

Export commands and supported formats differ between SketchUp editions and releases. If File → Export → 3D Model does not offer COLLADA, use a compatible SketchUp desktop edition or convert the file on 101convert.com for free without installing software. After an online conversion, validate the downloaded DAE in the target application and avoid uploading confidential or commercially sensitive models.

Convert with an existing DAE workflow

If SketchUp is available only for opening the source, export DAE directly rather than converting through another format. Blender can be used after that export for mesh cleanup or scale and orientation corrections: import the DAE, make the required edits, then export DAE again. Blender versions and installations differ in their COLLADA support, and an extra import/export cycle can alter object names, material nodes, smoothing, or texture paths, so it is not the preferred first conversion step.

Quality and compatibility limits

• Mesh conversion: SketchUp faces are exported as polygon meshes. Arcs, circles, curves, and other analytic or procedural elements become tessellated geometry; the result may contain extra triangles or duplicated vertices.
• Materials: Basic colors and image textures often transfer, but SketchUp styles, watercolor effects, renderer-specific settings, complex transparency, and procedural materials do not have consistent COLLADA equivalents.
• Texture files: DAE commonly references image files instead of embedding them. Keep the DAE and its texture folder together, or package them in one archive when delivering the model. Moving or renaming the images can break the texture references. PNG and JPEG files with simple filenames are usually the safest choice.
• Scale and axes: Confirm the destination application’s unit settings and up-axis. A correct mesh can appear tiny, oversized, rotated, or upside down after import.
• Organization: Groups and components may become scene nodes or separate mesh objects. Dynamic components, scenes, section cuts, guides, dimensions, labels, shadows, and SketchUp-specific metadata generally need to be recreated manually.
• Geometry cleanup: Purging unused content can reduce unnecessary data, but deleting hidden geometry or components can change the model. Make those changes only in a copy of the source.
• Validation: Test the exported file in the actual destination software. A generic DAE viewer does not prove that the target renderer, game engine, or CAD application will interpret every material, texture path, axis, and hierarchy correctly.
