OBD Member is rotated slightly?

Richard,

I have used Structural Member Rotation property input to get this work.

I have used Function DotProduct ,to get the dotproduct of 2 vectors , for that I have used baseCS.XDirection and CS.XDirection  [CoordinateSystems placed along curve].

Passed this dotproduct values to Rotation = Asin(Angles)  ..

Code looks like below

transaction 2 stateChange 'Change Angles, structuralMember1'
{
    gcModel
    {
        node User.Objects.Angles Bentley.GC.NodeTypes.FunctionCall
        {
            Technique                 = 'Default';
            Function                  = DotProduct;
            vector1                   = coordinateSystem1.XDirection;
            vector2                   = baseCS.XDirection;
            GraphLocation             = {1664.225, 32.703, 0.0, 152.4};
        }
        node User.Objects.structuralMember1 Bentley.GC.NodeTypes.StructuralMember
        {
            Technique                 = 'ByStartPointDirectionLength';
            CatalogItem               = {'Steel Column','Column'};
            StartPoint                = coordinateSystem1;
            Direction                 = coordinateSystem1.ZDirection;
            Length                    = 400;
            CrossSection              = '1000WB322';
            Part                      = {'Structural - Steel', 'Columns_BracedFrame'};
            Rotation                  = Asin(Angles);
            GraphLocation             = {990.6, 36.5};
        }
    }
}

See image below where I can see my Structural columns now properly aligned to Coordinate System placed along curve.

 [This should be by default align to CoordinateSystem, filing defect for this]

HTH,

will this defect be a patch that will be sent out to license holders?

Hello Richard,

If you look into the attached sample file you can see that i have used the By Points Technique to create the structural members, it works perfectly fine for me. https://communities.bentley.com/cfs-file/__key/communityserver-discussions-components-files/360/ByPoints-Structural.gct

and you please post the dgn?

Definitely, here is the dgn file. ByPoints Structural.dgn

Alifur, if I need to rotate the structural member by 180 degress? how will I do that? refer to snap shot.

Alifur, did you try to do all this with the file I sent you?
