I want to make flat surface when using bezier curve. Blender don’t make flat surface when I switch to 2D it only makes pipe type of bexier fill how I make 2D completely zero Z axis surface ?
Also without using mesh as follower of bezier curve but within the bezier object data properties only.
Not this type of bezier curve this I know of, but you know the basic 1 line bezier you get from the add menu as default so I can keep extruding the flast surface for example making scarf or road etc 
I know that I can use object I’m just wondering can this be done without using another object within the bezier menu.
No.
Any other bevel is some pipe thing and extrude makes this in Z… so no streets.
But you could use a mesh with an array modifer along a curve…
do you know why it isn’t possible? Why bezier curve can’t produce 2D plane without using object since it can produce pipe?
Also why there is 2D option that says when you hover mouse over it:
“Clamp the z axis”
This to me indicates that it should procude flat plane instead of pipe when chosen 2D option.
It means that curve control points are clamped to XY-plane.
You can use Geometry > Extrude option (without Bevel), and it will generate a flat strip, but you’d need to tilt it 90 degrees.
I tested that but it don’t keep flat when extruding more of the bezier curve the whole flat plane starts to twist different angles even when I extrude from absolute point in ortho mode, top ortho to be exact.
Mathematical Bezier splines are just curves… it’s the options in some 3D app which makes it possiblt to make surfaces based on them and in blender you simply has to use another curve for some extrusion along the 2D space only.
I found the solution and was already written in up, but this place seems to lag so hard that it didn’t get though.
Solution is to do it like Stray suggested, but he forgot to metion cruscial thing which is to to twist the angle of the other bezier curve point before starting to extrudin and after that the extruding works just like I was askin in my first post
I made file to anyone to see in the future.
I want only flat surface and taht’s it. Now it works exactly liike I want
solution.blend (844.8 KB)
Well… in fact i forgot about what @stray said and you only have to set some extrusion and set tilt to 90 degree… so:
What do you thing he forgot to mention about “the other curve” ?? ( I guess what you call twist is the tilt angle.)
yes straighten the other curve point to be exact, otherwise the flat plane will twist in all wierd ways
