Exporting Line Drawing from Perspective

I'm trying to export a perspective into a 2D drawing so that I can edit line weights and add effects, ideally in Illustrator. 

When I try exporting as a DWG, the file is a full model of the project, not the specific view I need. 

When I try printing as a PDF and opening it in Illustrator, it isn't actually a series of lines, rather it's an image so the lines aren't directly editable. 

Any other suggestions?

If you set the perspective view as Hidden mode without shadow then it should print to a vector PDF.  The screenshot below shows a vector being selected in Illustrator.

I am having a very similar problem in Revit 2018. When exporting 3d perspective view to PDF or DWG even from sheets, I would observe missing lines. I have tried in many ways to solve this and the problem appears to be the walls that come out of the scene or go behind the camera (towards it). I made sure they connect to the bottom, the top and are bound by it too. Please see the attached images and let me know if I am doing something wrong or this is a common problem withing revit and acad environment ?

Same issue here. No good solution found yet.

 

You could try change the 3d view to Consistent Colors then Export.  The colors (some, not all) will become hatches and you can use the Recreate Hatch Boundary command in AutoCAD to generate the lines.

Make a sheet that contain the perspective (either conic or parallel) and Export the Sheet to CAD. You will obtain a 2d drawing once opened in AutoCAD.

Yes we are talking about 3d view placed in sheet, exported to 2d DWG and the lines come toward the camera are missing.

In my tests (maybe they were less difficult perspectives) I did not encounter this problem...Only the crop rectangle is missing.

If lines to vanishing point(s) are missing in the exported .dwg  , I'll see which are missing and in Sheet view I'll draw some Detail Lines over the perspective view. Then export to AutoCAD. 

Once in AutoCAD, I'll open the Layout in which the exported perspective with my Detail Lines are shown ( in the model they do not show).

Then I'll save the Layout - Save As >Save Layout as Drawing , to make a new file that contain all the lines.

Thank you for your answer. It works although it is a rather long procedure for such a simple thing as exporting dwg. Now imagine if you have couple of perspectives per floor of a building that you need to redraw each time you deliver drawings and there are some changes to the design.

If you place the 3d view in a revit sheet and then export it from there, it will be made into lines when you open the AutoCAD
