## What is Sossial?

Sossial is a messaging and file viewing app for engineers who work with technical drawings. Open DWG, DXF, STEP and STL files right on your phone, take precise measurements, mark them up and discuss them with your team in chat.

2D DRAWING VIEWER
• Open DWG and DXF drawings without a desktop CAD program
• Smooth pan and pinch-to-zoom, even on large drawings
• Show or hide layers
• Turkish and international characters displayed correctly

3D MODEL VIEWER
• Open STEP, STP, IGES, STL, OBJ, 3MF and other common 3D formats
• Rotate, zoom and fit the model with simple gestures
• Toggle model edges for a clearer view
• Clear axis indicator so you always know the orientation

PROFESSIONAL MEASURING TOOLS
• Snap to endpoints, midpoints, centers, quadrants and edges
• Lines: length, direction, ΔX, ΔY and ΔZ
• Two lines: angle, or parallel distance when they are parallel
• Circles show the diameter; arcs show the radius, arc length and arc angle
• In 3D, tap a shaft or hole to get its diameter instantly; fillets are recognized and their radius is shown
• Distances and angles between faces, edges and axes, including wall thickness
