  Hello, My license is 2023 R2 educational. I have a problem with importing body in static structural section. Im a solidworks user on CAD side, Just created a bridge made of lines, exported it as step file and tried to import into geometry.
  this is the response I get
  And this is the line body I wanted to import
  This is the response I get when I create same sketch with design modeler:
  
  Please help.

    I am not sure if my problem is related to that. My problem can be simplified as 2D.

  Hi
  As mentioned in properties (Analysis Type) you need to set it to 3D as beam/lines will not work with 2D option.
  To have 2D in the 3D analysis then just fix the Z - direction on all nodes and the ROTX and ROTY.
  Set a snippet with:
  D,ALL,UZ,0
  D,ALL,ROTX,0
  D,ALL,ROTY,0
  That makes it 2D in principle

    Tried it in 3D too. Still did not work. I found the reason. There was no cross section dimensions. So when I attached a cross section dimension to sketch by design modeler, it worked. But I need something faster. A step file to be imported in sketch so I can define a cross section dimensions in the inside of ansys.
