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:

Format/Properties Mass Density Surface Volume
Catia Not available Read A3DMiscMaterialPropertiesData::m_dDensity Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
Solidworks Read A3DMiscAttributeData::SW-MassProp-Config-0* Read A3DMiscMaterialPropertiesData::m_dDensity Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
Creo/ProE Read A3DMiscAttributeData::MASS Read A3DMiscMaterialPropertiesData::m_dDensity Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
NX Read A3DMiscAttributeData::j0WeightCalc Read A3DMiscAttributeData::j0Density Read A3DMiscAttributeData::j0CPArea Read A3DMiscAttributeData::j0GeoV
JT Not available Not available Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
Inventor Read A3DMiscAttributeData::kMassDesignTrackingProperties Read A3DMiscAttributeData::kDensityDesignTrackingProperties Read A3DMiscAttributeData::kSurfaceAreaDesignTrackingProperties Read A3DMiscAttributeData::kVolumeDesignTrackingProperties
Solid Edge Not available Read A3DMiscAttributeData::Density Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
Revit Not available Read A3DMiscMaterialPropertiesData::m_dDensity Calculated A3DPhysicalPropertiesData::m_dSurface Calculated A3DPhysicalPropertiesData::m_dVolume
  • 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

Excuteme do you have any demo for this?

Hi!

To retrieve the physical properties in HOOPS Communicator you have to use the getNodeProperties() function, which will include the physical properties of the node among the properties defined by the CAD application.

Here is an example on how to retrieve the properties for a node using this function:
