I work in shipbuilding, and the problem that started this is a boring one: the drawing is on the workstation and the work is on the deck. Someone needs to check a dimension on a spool sheet, and the options are to walk back, or to print, or to keep a PDF that went stale two revisions ago.
There are viewers that show a Rhino model on a phone. That is a different job. What I needed was the sheet — the thing Rhino puts on paper — readable where the work happens. So I built that.
SRD Android CAD Viewer opens a .3dm directly on an Android tablet. Rhino’s own file reader runs on the device, so the drawing is rebuilt rather than converted:
- Model space and every layout tab
- Dimensions, leaders and text resolved to their effective style, per-object overrides included
- Hatches generated at the scale Rhino generates them
- Detail views, with annotation size resolved per detail
- Embedded images, draw order and linetypes
A layout is treated as what it is, a print preview. Anything set to “no print” stays off the sheet, whether that setting sits on the layer or on the object, exactly as in a Rhino print — a detail frame on a no-print layer disappears while its contents keep drawing. Model space is untouched: there, everything is visible.
The file is read on the device. No Rhino installation, no export step, no connection, and nothing is uploaded anywhere. Tap a .3dm in Drive, Downloads or Files and open it.
What it is not. It does not model and it does not edit. It does not measure — you can read the dimensions that are in the drawing, but you cannot pick two points and get a distance. It is not a shaded 3D presentation tool. And it is Android only; there is no iOS build.
Requirements: Android 5.0 or later, 64-bit ARM.

Free to download today. Development is active, and the most useful thing anyone can send me is a file that does not come out the way it looks in Rhino. I will look at it.
