Mechanical 3DShaft bracket with pulley, 3D
A 3D assembly: drilled base plate, upright with a bore, ribs, hub, shaft, V-belt pulley and bolts. Measure the holes, cut it, explode it.

Drawings with 3D solids, surfaces and meshes open in 3D. Orbit around them, slice them with a section plane and measure between any two points, on a computer or a phone.
Look at it from every side
Drag to orbit around the point under the cursor and scroll to zoom. Click the ViewCube for any of the 26 standard views: faces, edges and corners, with a smooth transition. Studio light with soft shadows and ambient occlusion shows the shape at a glance.
- Shaded with edges, shaded, hidden lines, wireframe and X-ray
- Model tree: hide, isolate or ghost any part, explode the assembly
- Dark or light studio background, save the view as a PNG image
See inside with a section plane
Slice the model along X, Y or Z and slide the plane through it. The cut outline is drawn in yellow and the inside faces show in a warm colour, so walls and holes are easy to read.
- Move the plane with a slider
- Flip the side you keep
- Click any object to read its layer, volume, area and centroid
Measure in 3D
Distances, angles, the radius and diameter of any hole or shaft, and the distance from a point to a face. Points snap to ends, middles and the centres of circles. Values are in the drawing's own coordinates.
- Radius and diameter of holes, shafts and fillets, with the centre
- Angle between three points, distance to a face along its normal
- Volumes of solids are calculated on the server from the exact geometry

Keyboard
3 and 2 switch between the 3D model and the drawing. D measures, S opens the section plane, E explodes the model, H hides and I isolates the selected part, V switches perspective, B the background, Z fits the model and Esc clears.
Which drawings open in 3D?
Drawings with 3D solids, regions, bodies, surfaces, meshes, polyface meshes or 3D faces open in 3D straight away. Drawings with only lines in space, like contour lines at their heights, open as a drawing and the 3D view is one click away.
Is the 3D model accurate?
The model is prepared on our servers from the geometry stored in the file. Volumes, areas and centroids of solids are calculated there from the exact shape, not from the triangles shown on screen.
Can I edit the model?
Not yet. Viewing, measuring and sharing are free today; editing comes with TrattoCAD Pro.
