Hello kangnguyen,
1) If you want to see 3D surfaces you have to use a 3D view (texture ≠ surface into Archicad) and you can use "parallel projections" into your 3D view -> then clic on File/Save as/PDF or JPG
2) File/Save as/Dwg since a 3D view or a 2D view with different options. About DWG you have to configure all DWG translator parameters before
😉 Files/Interoperability/DXF-DWG/DWG translators
Finaly you can publish a layout to create a PDF in a special paper size
