Extract mass properties from all configurations using SOLIDWORKS Document Manager API

This C# code example demonstrates how to employ SOLIDWORKS Document Manager API to extract mass properties from all configurations of the files in the input directory.

Result is output to the specified CSV file with the following columns:

File Path
Configuration Name
X coordinate of Center of gravity (m)
Y coordinate of Center of gravity (m)
Z coordinate of Center of gravity (m)
Volume (m^3)
Surface Area (m^2)
Mass (kg)
XX Moment Of Intertial (kg*m^2)
YY Moment Of Intertial (kg*m^2)
ZZ Moment Of Intertial (kg*m^2)
XY Moment Of Intertial (kg*m^2)
ZX Moment Of Intertial (kg*m^2)
YZ Moment Of Intertial (kg*m^2)

If there were any errors extracting the properties, this will be output to the CSV file

It is required to specify 3 command line parameters

Full path to an input directory
Fiilter for files
Full path to output CSV file
