Before you start
Prepare your Archicad 3D view
Archicad's 3D window already holds your design. Save the perspective you want, describe the finishes and setting, and use RenderChat to explore how the building could look before you set up a full rendering pass.
Choose a 3D style
Use a shaded 3D style with contours on and sun shadows enabled. Hide markers, grids and section planes.
Save the 3D window
With the 3D window active, use File ▸ Save As and choose PNG at 2000 px or wider. A full-screen screenshot also works.
