How to acquire those profile sections values as Ix, Iy .... values, lot of them?

[Anonymous]

It seems that although I teached this for my workers years ago, I don't remember it now when i need it.

Who remembers, I remember it being two step procedure to list those. I do not have any old Handbooks available to search from books.

Hi,

>> profile sections values

Are your referring to AutoCAD (according this forum) or Autodesk Civil 3D (which would be the product knowing "profile sections")?

Those commands already existed in old AutoCAD. They are there, but I do not remember ;>(

The need is for steel profiles, nothing to do with earth surface or something like that.

For example, if you turn steel profile some degreeds, those moments of inertia values are different compared to straight position.

Hi,

Can you show a dwg-file plus the output you have got previously?

Hi, I don't have anything here at home now, but the section from any HE?- profile turned some degrees and one can acquire those inertia values with two AC-command, which I do not remember any more.  ;>(

Hi,

>> with two AC-command

1) command _REGION to get a closed object

2) command _MASSPROP

Is that what you are looking for?

I checked this command (text of it ) and can say that those old AC commands give more info that this one.

Hi,

I guess we need a sample of what they returned.

BTW: have you seen (and looked into) my link in post 7 of this thread?
