Engineering tools – weight, tap drill, ISO fits and STEP
- CAD ViewerOpens .STEP, .STP, .STE, .IGES, .IGS, a SolidWorks .SLDPRT or .prt, a 3D Studio .3ds mesh, or a Rhino .3dm that already has a display mesh. Measures length, diameter, radius, angle, or the area of a face in square millimetres. This page does not write a converted file. The file never leaves your device.
- CAD ConverterConvert a SolidWorks .SLDPRT part to STEP or IGES, or write exact STEP, IGES and DXF edges. .3ds and Rhino stay a mesh. The file is not uploaded.
- Material Weight CalculatorSteel plate, bar and tube — weight from dimensions
- STEP, STP, IGES & IGS WeightUpload a .STEP, .STP, .IGES or .IGS file, or a SolidWorks part, .3ds or Rhino file → volume and weight.
- All-in-One Unit ConverterLength, pressure, torque, temperature, data and more
- Thread & Tap Drill CalculatorMetric, UNC, UNF, UNEF, BSW and BSF tap drills
- Tolerance CalculatorLimits, fits and ISO 286 deviations
STEP / CAD
- CAD Viewer · Opens .STEP, .STP, .STE, .IGES, .IGS, .SLDPRT, SolidWorks .prt, .3ds, .3dm and ASCII .dxf. Does not convert files
- CAD Converter · Writes STEP, IGES or exact DXF edges from a .SLDPRT or an elementary solid. Does not write .3ds, .3dm, .prt or .SLDPRT
- STEP, STP, IGES & IGS weight · Mass from a .STEP, .STP, .IGES or .IGS file, or from SLDPRT, .3ds or Rhino
