3dosnaps

[gkarchitect]

 My problem is I want to 3dorbit to certain views and then draw plines snapping to endpoints and intersections with different x,y,z coordinates. I tried enabling 3dosnap but it still isn't quite getting me where I want to be. I'm exploring various options for a geometric roofing extension but seeing if there is an easier way to lay out different sloped roofing panels. At the moment I lay them out on one viewpoint, align them from another and then drag the snap points to line everything up before I extrude them.

I am not sure what your problem is, but it looks like you want to draw a 2D Polyline(command PLINE as you wrote),

that shouldn't be a problem, but if you want the PLINE on the right position you have to set you user coordinate system first!

command: UCS

Or explain it in other Words, pictures or DWG files.

Q: are you trying to generate a 3D model from your 2D content? Or are you trying to draw isometrics?
You have 2D content if your screenshot is any indication, so why the need for 3DOSNAP?

I'm working on 3d renderings. 1st one was easy but I'm having issues trying to extrude a surface that not only is irregular but needs to be sloped. Like a pentagonal roof in the screenshot. This was the first one, added people after rendering and haven't added shadows yet.
