List of physical properties retrieved by HOOPS Exchange

Depending on the input CAD format read, the HOOPS Exchange API is able to retrieve or re-compute several attributes concerning the “physical properties” (like the mass or volume) of a model.

As its name suggests, the A3DComputeModelFilePhysicalProperties() function is able to re-compute several information like the surface or volume from a brep. However please keep in mind that those values may slightly differ from the native CAD software ones since the modeller used is different !

Concerning the values that are directly read from CAD files, here’s an array with their different names:

  • The SW-MassProp-Config-0 attribute displays the following data in that order: X, Y, Z Center of Mass (meters) / Volume (cubic meters) / Surface (square meters) / Mass (kilograms) / X, Y, Z Axis of Inertia
