Render your SketchUp or Revit model online

Drop a SketchUp or Revit export to light it with a real sun position, swap in sports surfaces or your own images, place it on a site photo and save a render. A demo stadium is loaded so you can try every control first.

SketchUp: .skp opens directly, or .dae .kmz .obj .fbx or a .zip with textures · Revit: .ifc or .fbx · Rhino: .3dm · CAD: .dxf · also .glb, glTF in a .zip, .usdz .ply .3ds .stl · Images: .jpg .png .webp. .rvt needs a one-step IFC export.

Light

Real sun, real shadows

Set sun altitude and direction, or pick midday, golden hour, overcast, studio or a floodlit night. Shadows are cast at the model's true size.

Surfaces

Sports finishes in one click

Swap any SketchUp or Revit material for synthetic turf, PU track, acrylic or clay court, maple, PP tiles, water or glazing, scaled in metres, or use a photo of your own material.

Privacy

Your files stay on your device

Models and photos are opened by your own browser. They are never uploaded to DesignDenzi or anyone else.

If a .skp will not open

Export from SketchUp in under a minute

Most .skp files from SketchUp 2013 to 2025 open directly. If yours does not, a COLLADA export keeps your materials and textures, and SketchUp includes it in the desktop app.

  1. Clean the model

    Purge unused components and materials (Window → Model Info → Statistics → Purge Unused). Smaller files open faster.

  2. Export as COLLADA

    File → Export → 3D Model, then choose COLLADA File (*.dae). Keep texture maps switched on in Options.

  3. Zip the export

    SketchUp writes the .dae and a texture folder with the same name. Select both and compress them into one .zip.

  4. Drop it in

    Drag the .zip onto the viewer above, or use Open your model. OBJ with its .mtl, FBX, 3DS, KMZ, GLB, USDZ, PLY and STL also work.

From Revit

Export from Revit as IFC

Browsers cannot read .rvt files. Revit's built-in IFC export is open, keeps your model in metres and splits it into walls, slabs, roofs, columns and windows, so each category can take its own finish.

  1. Hide what you don't need

    Large linked models, furniture and annotation slow things down. Use a 3D view with only the elements you want rendered.

  2. Export IFC

    File → Export → IFC. Choose IFC 2x3 Coordination View 2.0 or IFC4 Reference View. Tick "Export only elements visible in view" to keep the file light.

  3. Or export FBX

    From a 3D view, File → Export → FBX keeps Revit's material colours instead of categories.

  4. Drop it in

    Drag the .ifc or .fbx onto the viewer above. Large IFC files can take a minute to open on a laptop.

Images

Put your design on the real site

Drop a site photo behind the model and its shadows fall onto the photo's ground. Lay a site plan flat at real scale to check the layout, or use a photo of a real material as a finish.

  1. Site photo

    Drop a .jpg or .png and choose "Site photo or sky". Use the Eye level view, match the lens, orbit until the horizon lines up, then turn the sun to match the photo's shadows.

  2. Plan on the ground

    Choose "Plan on the ground" and type the real width of the drawing in metres. Move and rotate it until it sits under the model.

  3. Your own finish

    Click a surface, then "Choose an image for this surface" in the Surfaces tab. Set the tile width to the real size the photo shows.

Finish library

Surfaces drawn for sports work

Every finish is generated in the browser at real-world scale, so a turf blade or track granule reads correctly whether the model is a single court or a whole campus.

    Questions

    Common questions

    Can I open a .skp file directly?

    Yes. Drop the .skp and your browser reads it with OpenSKP, an independent open-source reader that is not made by Trimble; the file is not uploaded. It reads most files from SketchUp 2013 to 2025. Some versions, 2019 in particular, do not open yet: export those as COLLADA (.dae) and zip it with its texture folder, or send the .skp to our studio on WhatsApp.

    Can I convert a .skp file to .dae?

    Yes. Open the .skp, then choose Project → Download as .dae. You get a COLLADA file in metres with Z up, plus a texture folder in a .zip when the model has textures. It opens in SketchUp, Blender, 3ds Max, Lumion and most other 3D software.

    Can I open a Revit .rvt file directly?

    No. RVT is a closed Autodesk format that only Autodesk software reads. Export the model from Revit as IFC (File → Export → IFC) and drop the .ifc here. FBX exports from a 3D view also work. If you would rather not export, send the .rvt to our studio on WhatsApp.

    Can I open Rhino or AutoCAD files?

    Yes. Rhino .3dm files open with the meshes Rhino saves for display: if a surface is missing, set a viewport to Shaded in Rhino and save again (not Save Small). AutoCAD drawings open as ASCII .dxf: lines, polylines, arcs, circles, 3D faces and blocks are read in the drawing's units; text, hatches and splines are left out. For a .dwg, use Save As → DXF in AutoCAD first.

    Which other 3D formats open?

    glTF and .glb, USDZ (for example from Blender; animation and some advanced USD features are not shown), PLY scans and meshes with their vertex colours, plus .dae, .kmz, .obj, .fbx, .3ds and .stl. For a glTF with separate .bin and texture files, zip them together and drop the .zip.

    Can I turn a photo or a sketch into a 3D render?

    Not by itself. A photoreal render needs a 3D model, so this tool renders models you export from SketchUp or Revit. Photos and drawings can sit behind the model as the site, lie flat under it as a plan at real scale, or become surface finishes. For a render made from your sketch, our studio can model it for you.

    Where are my saved projects kept?

    In this browser on this device, using its built-in storage. Nothing is sent to DesignDenzi. Clearing the site's data or using a private window removes them, so download the renders you need to keep.

    Is my model uploaded anywhere?

    No. Your browser opens the files on your own device and they never leave it. We record anonymous usage counts, such as which file format was opened and whether a render was saved, to improve the tool.

    Is it free?

    Yes. Free renders are saved up to 1,920 pixels on the long edge with a DesignDenzi watermark. Pro exports remove the watermark and save at 4K with an unlock code.

    Why are some textures missing?

    The .dae file only points to its textures. Zip the .dae together with its texture folder, or drop the whole export folder at once, so the images travel with it.

    Some faces look odd or the model is on its side.

    Both sides of every face are rendered, so reversed SketchUp faces still show. If the model lies flat on its side, tick "Model is lying on its side" in the Model tab. If the size looks wrong, change the file units there.

    How large a model can it handle?

    It depends on your device's graphics. Hide entourage and purge unused components before exporting to keep the file light. Turning off contact shadows in the Light tab also helps on slower machines. For Revit, export only the elements visible in a 3D view.

    What software does the tool use?

    The viewer is built by DesignDenzi on the open-source three.js library. Revit IFC files are read with the open-source web-ifc library (MPL-2.0, licence) and Rhino files with McNeel's open-source rhino3dm (MIT, licence). DXF drawings are read by DesignDenzi's own reader. Nothing is sent to an AI service.
