hare0105, if you run simulation for CPW or microstrip circuit, make sure the dimension is properly defined. Check and view the layout by a clicking "layout" shortcut at the top window. you will see the layout converted directly from circuit to layout. If you use any lumped element or active device in your circuit window, which default layout is blank, you will see the distributed layout after conversion. Therefore you have to create them (lumped element or active device)seperately and link to symbol in circuit window.
If the layout is fine, then you can export it in format like dxf, gbr, etc...
