A quick aside, I saw instructions for how to put my software version in my signature but when I went to the signature section I couldn't see how to do it. I'm using Home Designer 2020 on Windows 10. Rookie65, it sounds like you get it. It's the bottom of that cone you described that I'm looking for. Where it hits the front wall tells one the low point of a screen--screens' bottom to the flloor (e.g. 20") so that the screen may still be viewed--even its bottom edge--from the second row.

Hi, the Home Designer rep I spoke with said that I could use this software to design two rows of seats, one elevated and behind the other, and see the line of sight that those seated in the rear row would have of the wall they're facing (i.e. the front wall). This is for a media room. Knowing the area of the wall that is viewable to those seated in the rear row will tell me at what height to mount a screen on the front wall. I've made my room and my rows of seats and in the full camera 3D view I see a rendering that is exactly the sort of rendering I need. All that remains is to be able to draw a line between a seat headrest in the rear row and the front wall. The line would be sloped downwards as it goes towards the wall, so that it just touches the top of the front row seats as it goes towards the front wall. I see that the CAD portion of the software allows users to draw lines but only in "plan" view. Please advise.
