RSA section definition

[Anonymous]

Hi. I have to analyse aluminium frame structures and want to import the sections as .dxf.

There's no problem about importing the shapes but as İ make a change on it, the values are changed. 

As seen in attachments under equal conditions one of the applications include changing the material type of the section and one doesn't.

Why the values of inertia, gravity coordinates etc. change?

When we have a material or opening change, dimensions of the little elements change.

How can we prevent this totally or does RSA has a error limit about it?

The difference should be caused by the difference in cross-sectional area. Do you notice the difference between those two values caused by any difference of the two imported drawings? I mean that difference could belong to somewhere in the cross-section.

It's the same section imported in all pictures.

Thanks very very much.

I was sure that was the problem but I realised that  I've already been working in milimeters =/
