Tube command Problem

[Nader Belal]

Hi there,

I was trying to make this hand bar for a ladder, using "Tube" command in ArchiCAD 18, as you can see in this image.
The problem that I have got, is that the profile gets skewed in plan, and I have got no clue how to set it right, by rotating it around its center axe.
PS: I have also tried to use Xform, but to no use

There is a post on GDL_Center that is talking about tube twisting and apparently there is a new macro in 21 called 'Gravity_tube' that may help.

My only other suggestion is the TUBEA command that has no twist angle settings.
I have never used it so don't know what it would be like.

I have no idea about the shear angles.

Barry.
