What you can do with your MODEL file
Rotate, zoom and pan
Turn the model with the mouse or touchpad and zoom in on any detail. Front, Top and Isometric views are one click away.
Measure distances and angles
Measure Distance shows the distance between points you pick on the model, and Measure Angle the angle between edges.
Cut a section
Section cuts the model with a plane, so you can look inside it and check walls and cavities.
Check size and volume
Bounding Box draws the overall size. The Information panel shows the dimensions, volume, area, triangle count and holes.
Convert the file
Save your MODEL file in another format on the converter pages below or in the free desktop app.
