Repeating but …
A means to RELIBABLY create a 2d plan from a 3d object.
What about reliable spelling?
@miano are you referring to the Make2D command in Rhino?
The failings of Make2D.
If you want improvements to happen you should clearly give steps that fail, that are reproducable, share specific geometries/files that fail.
Do not assume readers (dev or otherwise) know what you are talking about without providing enough context.
Just crying you want improvements is not helpful, it isn’t very actionable. The question from Steve already is a great indicator that it isn’t clear what you are talking about.
“Feature A sucks” is useless feedback because it doesn’t explain why and how feature A sucks.
“My stuff not working. Plz help me!”… “I h8 this bug. Can’t u fix it?”… “How do I model a car?”
Amazing how many people still believe in mind reading capabilities.
Ever since I was a teacher (last millenium) I have practiced mind reading. But unfortunately never succeeded 
I was trying to make a simple isometric drawing of a part for the first time since I moved from AutoCAD into the third dimension at the end of the 20th Century. Reader, I was also frustrated by the process.
What I really wanted was to be able to simply output the 4View on my screen, with a title block, but achieving that meant having to split the screen into six(6) views (to accommodate a title block), turn off the viewport titles, make the borders the same color as the background, and then take a screenshot and print it to pdf.
After all that, Make2D started looking somewhat better, but what if I just want shaded views and not vectors?
Am I missing one or more important and fundamental techniques here?
Thx
Hi, just add four details (shaded, rendered, wireframe, whatever) to a new layout representing the four views you mentioned, add the title block, print to pdf
Lol thx @mc_rash 
You are welcome!
FWIW, I have submitted numerous examples of Make2d failing over the years. New versions of Rhino come out and each time Make2D still does not work reliabily. Either Make2d needs to be fixed or there needs to be some alternative mechanism to do the same, such as some display mode that can accomplish the objective.
Hi John -
I’m afraid there is not going to be one single “fix” that solves all issues with the Make2D command. This is an ongoing process. Several fixes to the command have already found its way into Rhino 9 that are not in previous versions.
At present, an alternative way would be to print a viewport in a technical display mode to the vector PDF format. The code that is used to create that vector output is partly the same as what Make2D uses but also differs in enough ways that might be beneficial to your specific case(s).

The display method almost works. The problem is the display options are not consistent. Pen mode almost works but it displays tangent lines. The appears to be no setting to hide tangent lines as there is in, say, shaded mode.
please always send us models and screen shots of the failings so we can get this tuned up.
the more input we get that is not working, the faster we can sort out what is happening and fix it.
Is there some technical reason why one cannot disable tangent seams in pen display mode while you can in shaded?
Hi John -
Yes. Those are two completely different display pipelines with different options. There are plans to merge both but that is not something that is on the table for now.

I add that I am getting the beach ball for about a minute when I switch to Rhino with that file loaded. I have can another Rhino file loaded and visible and still get the beach ball.
