About this app

STEP-BY-STEP BUILDING
• Parts list for every step, with colour and your progress in each batch
• A window with the next part, and the part highlighted on the model
• Portrait or landscape, and distraction-free full screen

IMAGE QUALITY
• Cinematic shader: realistic plastic, metal, rubber and pearl
• Rim light so dark parts keep their shape
• Accurate outline edges, skies and environment reflections

NEARLY 15,000 MODELS
• Catalogue with links to LDraw models, cars, motorbikes and much more
• Open your own files from the device or from a download
• LDraw parts library downloadable or from your own ZIP, offline

FORMATS
• Reads LDraw (DAT, LDR, MPD, L3B), LXF/LXFML, 3DS, LWO, OBJ, STL, PLY, OFF, DXF and PRJ
• Exports to OBJ, STL, 3DS, LWO, OFF and POV-Ray choosing the number of triangles, ideal for 3D printing
• Also exports a JPG image and the parts list

HUGE MODELS ON MODEST PHONES
Buf3D uses a version of the Progressive Fans technology developed by Antonio Cortés Carrillo: it builds and displays multiresolution models of millions of triangles out of core, adjusting the detail in real time.

Plus: live wallpaper with your models and experimental Cardboard / VR glasses mode.

Ratings and reviews

Great App. I've been looking for ages to have a viewer of LDraw files in my mobile. Can I use Custom Library A or B option to add a folder with custom parts? What's the path syntax to do it? Thank you. With the option of adding my custom libraries this wonderful App as become my most valued asset. No long do I have to carry my notebook with me to show my models around. Could you please let me know if there is any way to add/edit the online model libraries in the DIR tab? Since I have most of my models available to download I would like to create an entry to the host server instead of having to download the model again every time I update one of them.

Great at viewing and exportihg Lego models (all I have tried it for) - even has a browser for a load of models it gathers from the internet

Just keeps getting better. So many great features. LDD import is super.
