massprop calculation issue

edited December 2020 in 3D Modeling

I got strange output from massprop command: volume is 2.0e-3% less than manual calculated.
As a test create cylinder with radius 1000 mm, height 1000 mm. Command is showing value of 3141529508.8647.
Units set to 8 decimals so the error is still 1000 times larger.
Acad is showing exact value of PI * 10e9
Is it known issue?

Thank you,

  • Odd. Running same v21 version on Windows 10 and also with v20, I see the same error in cylinder volume. However, its surface areas appear to be calculated correctly, as do volumes for prisms and spheres.
    And (+ pi 0) returns pi correctly to 14 decimal places.
