How do I know the position and pointing direction of lights for rendering?
I built a 3d model in progecad Pro 2010. When I go to "lights" how do I know what side of my model the light is pointing to, or where the light is coming from?
I try variations using the azimuth and elevation but it's difficult without a reference point in the drawing.
I used Vectorworks in the past and I could insert light icons in the drawing to help orientate the lights direction and elevation. That was very helpful.
I will need to ask some others to help with this question as I am not sure of the answer. If the issue does not have an answer I will see that it gets added to the development efforts to make sure we make that information available in the future.
To add pointing lights that will be displayed in your rendering you have to run the "lights" command.
First of all add a new light and specify its X,Y,Z position. To identify a particular location run the "id" function, you need to type it in the command line. After you specify a particular point selecting it (you could activate a particular esnap) its coordinates will be displayed. To direct your light you have to place it inside a 3D model (e.g. a hollow cylinder representing a spotlight).
To display shades run the "fullrender" function.
