Autodesk Robot Structural Analysis

See attached picture

I am trying to link two members (522 and 521) for design. The bottom node of the resulting member should be #1741 and the top #1740.

However, when I go through the process of linking these bars to act as a single for design, the orientation switches. The resulting member has node 1740 as the bottom, and 1741 as the top.

What have I done wrong? Is there any way of controlling this?

Please attach the rtd file with these two bars .

See attached for a model showing the bay with the columns I indicated earlier.

Also, you can see that the combined section 9000 (and 9030) is defined top to bottom, while 9010 and 9020 are defined bottom up. I was hoping I could find a way to to control these definitions.

File

Thanks

I'm sorry but I'm not able to download the file from this location. Could you delete all but the part of the model with these bars and save such rtd file under a new name please? After compressing it you should be able to attach such created zip file. Thank you.

Got it.

The origin is in the node that has got  a lower number. The way of controlling this is shown on the attached picture.
