I'm looking a simple way to diagram sight lines with angles and dimensions. I've thought of

SketchUP
Visio


I'd prefer not to spend hours learning the software.

Actually, I want to pop in the dimensions, have the software generate the angles and them modify the dimensions to see how the angle change. Plus the interference between the 1st & 2nd row.

For Visio, Microsoft has a 60 day trial and there's a free viewer available.

I've always sight lines with a simple 2D drawing app like Illustrator because I've know it since the beginning of time and it takes me like 10 minutes to sketch something up in plan and elevation separately. There's an open source alternative called Inkscape that might also work well.

For 3D, I love SketchUp, and I've been using it for years. The free version is more than adequate, whatever time you spend learning the basics enough to figure your angles, you can use on future projects. I've used SketchUp to design everything from the theater to a deck, furniture, and a custom handrail I built in my last house.

No comment on Visio. I don't use it and never have. I know it's powerful, but it always looked like a giant pain in the ass to me. I also don't like time-limited trials since I'd no doubt put it aside, then not got back to it until after the trial expired.

Why not a ruler, pencil and graft paper, to create a scale drawing?

It's pretty tough to experiment with different heights and such, because you have to keep redrawing, but yes - old school pen and paper is as simple and free as it gets.

Just draw the room on the graph paper and do scale seating and screen as cut outs. A
straight edge will give you the sightline.

One item seldom mentioned, is make sure the front row elevated head angle doesn't exceed
seven degrees, if you mount the screen on the higher side of things, to tweak sightlines.

The Visio trial did what I needed
