I made a column as a truss and got lot of errors. No idea what else can I change. I added only self-weight and even though there are 10000m displacements.

Hi @Anonymous
Try to set the 4 column as "simple bar", not truss

Sorry for german menu. Gelenke = releases. I tried also to make all the bars pinned-pinned
Can you attach your model?

@napooil Ok, it works, however I'm not sure if I attached windload properly.
Nevertheless what is the point of designing 3D truss when at the end you need to change it into a 3D frame?
Do I have to set all the bars as pinned-pinned or pinned-fixed or can I leave it as a fixed-fixed?
@Simau I can't see them. How can I delete them?
Select all the structure then

Your original model cannot be qualified as a 3d truss . In this "geometry type" all bars are automatically treated as truss bars. So , all nodes/joints are pinned which makes some of your nodes unstable.
So , that´s why it will only work only if it is treated as 3d frame .On Those unstable nodes above , Shear on the vertical chords would make the structure stable.
