MSasu Posted March 2, 2012 Share Posted March 2, 2012 I'm afraid that your image isn't visible - please check this tutorial for image attachment procedure. Regarding the calculation of volume, seems that since you are using LT the 3D modeling and MASSPROP command are out of question; you will have to calculate the volume by hand and multiply it with the density of material. If you will manage to attach the image, maybe someone with full AutoCAD will find the time to help you. Regards, Mircea Quote Link to comment Share on other sites More sharing options...
WERDNA Posted March 2, 2012 Author Share Posted March 2, 2012 File attached this time, maybe mass properties is not the right description, it is the second moment of area in particular that I am after? Quote Link to comment Share on other sites More sharing options...
