C’set 3DTascalX
"3DTascalX" is equipped with the same solid kernel (Parasolid) as many 3D CAD/CAM systems. It achieves high-precision relative measurements down to nanometer (10⁻⁹) levels, and allows for absolute measurements from any coordinate, capabilities that typical polygon viewers cannot match. 3D models can be viewed in various ways, and it is easy to convert them to 2D drawings.
