Hello.
I have a question: I would like to obtain a perspective like the one attached, namely hidden line + shading in Archicad. No matter what I do, however, using either the internal or the external engines, with sun shading or not, I do not get it.
Does anybody have any idea? Thank you.
Your target rendering is not a hidden line rendering,
rather it is a shaded rendering wherein all the materials are white.
The clue is that the shadows are uniform gray scale.
Search the forum for ways to substitute material attribute *.aat files, it is a quick method to change all materials to white. It does take some time to create an all white palette of materials, but once done you can load and unload it at will.
Try a sketch render but make sure your materials do not have any hatching patterns attached to them. the attached rendering would of been all white with shadows, but I have patterns assigned to the materials (shingles, stone etc.
