Oh, does D3DXMesh still exists ?
Nope. The D3DX library was not maintained after D3D9. It's used by the example code for D3D9 only, it's not a "real" part of DirectX.

Planning on using Blender
In addition to what Hodgman said, I believe they moved a lot of the functionality out to the DirectX Took Kit. Looks to me like they took a lot of that stuff out between DX10 and DX11 including Sprite and Model support. I think they did DXTK as a way to give it back to those who wanted it. I believe a lot of pro-game developers were basically writing their own anyway and they wanted to offload it.
I haven't tried DXTK myself. When I was doing DX11, I was bound and determined to figure out how to do it all myself. So, I built my own model class, exporter, and importer. Then I serialized the class to save the binary data out to disk. I would have gone on to make it support skinned animation. I got as far as doing a test run using XNA to play back Blender humanoid animation data as stick figures, but then decided to start doing OpenGL instead and had to start all over learning OGL. Then I got side tracked again with learning 3D modeling. Learning Vulkan is on my agenda but really before any of that I have to get my new computer built as the parts have been sitting here collecting dust since Christmas.
I never used D3DXMesh directly. I think what I was doing in XNA years ago was calling it to get the job done behind the scenes.
There's also ASSIMP for models although I don't know exactly how much it does for you since I haven't tried it. I've thought about trying to work ASSIMP into my OGL engine rather than rewriting my DX model class to support OGL. I can see some advantages to both and so I'm still not sure which direction I'll go with that if I ever get the time.
I actually have a bit of deprecated code in my DX11 engine. Some of it is probably because I wrote it for Windows 7 and MS no longer really supports that wanting everyone to use Win10. Apparently, there's no "good" way to get keyboard input in DX11 and hasn't been in DX for a long time. I'm using DX8 code to communicate with the Keyboard rather than going through the event loop. I think some of the error handling was deprecated code as well. I tried to avoid anything deprecated, but there seemed no good way to do some things in DX11 for Win7 without using deprecated code.
So, I'm guessing you could actually include D3DXMesh in DX11 or DX12 code.
Really, all a model is is a vertex buffer and an index buffer. The hard part is done in the modeling software to build all those vertices and assign them data. I made mine to import sub-meshes so that the model could be in different parts. That's mostly to support rigid animation, so that the parts can be animated separately. But I put it all in a single vertex buffer.
If you support skinned animation, it gets quite a bit more complex. You have to have all the skinning data such as vertex groups and weighting information to know how much each vertex is assigned to each bone in the armature. And you have to have the armature data itself (bones), which is a bit different from the sub-meshes having their own matrices in rigid animation. Then of course, there's all the animation data for the armature and calculating frames between the key frames.
I'm not sure if D3DXMesh supported animation. I'm betting it did because I seem to remember doing a tutorial once where I got a model to animate back in the DX9 days and back then I had no clue what I was doing. In fact, I failed to learn DX9 after a few years of effort. XNA came along and that's when I actually started figuring everything out and in XNA the model class did not natively support skinned animation. Then I went into DX11 without ever really learning DX9.
Agreed with what most people are saying here with the two main points.
- Blender is cost effective and produces similar results (has a great community and lots of plugins).
- Using Blender solely for that format is perhaps not the best use since it is not commonly used now.

Thanks for the reply`s
For the toolkit i see no download for XP & Win7, maybe i stay with old trusty DX9,
only it would be very handy to make stuff myself, i might understand things better for optimizing.
That means i have to make a blender export plugin, i bet there are enough examples for that in C.
I use vertexbuffer for the LevelMesh, only indexbuffer i dont know exact how it works, it seems i need it for the models.
And skinned animation is something i would like, only i dont wanto get involved in these seperate shader files for animations,
i want everything done in 1 source code file, not learn a new shader language on top, i dont know if that is possible ?
I think you have to use Python to write a Blender exporter. If you find a way to do it in C, let me know, because I pretty much hate Python. Then again, I only learned enough Python to write a Blender exporter. So, I imagine my code has plenty of room for improvement. But here is my Blender Python model data exporter:

There is no advantage to exporting to a binary format unless that binary format can be loaded straight into your data types, which at the very least would require a much greater knowledge of Python. What you really want to do is load your model class with this data and then serialize it so that the binary model file perfectly matches your model class data and thus is most efficient for loading into the model class to load a model. So, whatever you export, it's probably going to get converted; so it might as well be human readable.
This format is similar in some ways to the OBJ format which might be a good one to learn as well.
I called this file format the PUNC file format for Position, UV, Normal, Color as that's the data in the vertices. The first line allows you to verify that it is a PUNC file. The second line identifies the type of PUNC file as I was planning on a separate format for skinned animation from the rigid animation format. Then it goes into a loop of model parts/meshes. The first line in the loop is the sub-mesh name which in this case is the body of the car. If the sub-mesh has a parent because it was parented in Blender the second line in the loop will identify which sub-mesh is it's parent. (I believe there are two ways to parent something in Blender and one works for this and the other doesn't, but I can't remember off the top of my head what that is.) The CarBody has no parent, which makes it the root mesh and it will be the parent of all the others (which are wheels).
The next line identifies the material used for the sub-mesh. I think this allows multiple materials per sub-mesh assigning each a number starting from 0. Then the T identifies any texture image file used for that material and C identifies any color used for the entire material.
After that it has the WMR lines. This is a world/object matrix for the sub-mesh. I think WMR stood for "World Matrix Row". It's just a 4 by 4 world matrix. These matrices are the relative positions and offsets of each sub-mesh from each other as assigned in Blender. In this case, this positions the wheels relative to the car body. And the body is an identity matrix basically placing it at the world origin.
Then it goes into another sub-loop describing "faces". This is going to use a triangle list rather than a triangle strip or triangle fan. So, it's basically a list of triangles. But Blender basically does things in faces rather than in triangles. So, the first face has four vertices. You have to figure out how to break this up into triangles. I assume all Blender faces have co-planar triangles, which means it should not matter how you assign the edges to triangulate the face. I usually triangulate the model in Blender before exporting. I've only tested this format a little and so there may still be some bugs. I think the most complicated model I tested with was Blender's Suzanne monkey.
But for each face it gives the material number which references the texture and color at the beginning. Then it defines a face normal. And I think the S value was for flat shading or smooth shading allowing some faces to be smooth and others faceted in the same sub-mesh. As I get better at modeling, I am appreciating that more. Then it's a vertex list of all the vertices in that face, their positions, UV coordinates, vertex normals, and colors. Note that you may not always use all of these values. UV coordinates and vertex colors are often mutually exclusive. You tend to use one or the other, but not both. You can use both, which is why it's like this. But usually you either use a texture or vertex colors and not both at the same time.
So, then it just repeats that loop going through every face of the sub-mesh and expecting you to break the faces up into triangles. The list ends when you hit the name of the next sub-mesh. I don't think the sub-meshes are in parent-child order and so you may have to read them in and then figure out which is the parent and which is the child.
The file ends when it lists the "Total Unique Vertices". Looks like that total number of materials is broken. I don't think I actually used those last 3 lines when reading the data back in. But that's basically all there is to it. It allows you to build a vertex buffer. And there's enough info there to build an index buffer if you want. My code loads the entire model and all its sub-meshes into a single vertex buffer and then uses offsets in the buffer for each sub-mesh.
In my C++ code, I used two classes for the model. I have a Model Compiler class that reads this file and I have a RigidModel class that it reads the data into. The model class looks like this:

The entire project is on my website for download including the Python script and the textures for the model. The Python above is the abreviated version. The Python file in the project file has a bunch of other Python scripts that may prove useful in understanding the Blender data and how it is organized. I found getting info on the Blender data to be next to impossible. I actually "discovered" the Blender data layout through trial and error by just fishing around until I figured it out over a couple of months. Fortunately, Blender is really good about helping you on these fishing expeditions. Still, a lot of what's in the full Python file is stuff that I fished around and found and will likely be useful in figuring the layout of the data.
http://virtuallyprogramming.com/DirectX11/Tutorials/Tutorials.html
If I understood you right, you said you don't know how an index buffer works. It's pretty straight forward. The index buffer is just a list of which vertices to process in what order. This allows your vertices in your vertex buffer to be used out of order and multiple times. For example, a quad (rectangle) made up of two triangles, might have an edge where two of the vertices are identical in both triangles. They are shared vertices. So, instead of specifying 6 vertices for the two triangles you only have to specify 4 and two of them get re-used in both triangles.
In that case, your vertex buffer might looks something like: 0,1,2,2,1,4
The graphics card knows that every 3 vertices makes a triangle. So, the first triangle is 0,1,2 and the second is 2,1,4 where vertices 2 and 1 are used in both triangles. Then your vertex buffer only has 4 vertices instead of six making your vertex buffer a whole lot smaller and saving memory on the graphics card. For a 4 byte integer (I believe it is) you saved a vertex which in the PUNC case is something like 11 four byte floats I believe. It can save a huge amount of memory.
But all it really is is a list of which vertices to process in what order. Every 3 values is a triangle. At least, I believe that's the way it works with a Triangle List(It's been probably a year since I've written any graphics code). In a triangle strip, I believe every vertex is a new triangle and it uses the last two vertices defined to form the three sides of the triangle. In that case, all the triangles are connected by definition. So, it only takes one vertex (plus the previous two) to define a triangle. I would love to use triangle strips in my model (because they are substantially more efficient), but I doubt it's even possible. I gave up on that a long time ago and just use a triangle list.
Oh. Also be aware of your "winding". Back face culling will remove the backside of the triangle, if it is turned on. It determines which side is the backside by whether the vertices are defined clockwise or counter-clockwise. So, the order you define them in is important. You want back face culling on because it saves the graphics card from having to draw back faces that will never be seen by the camera such as the inside of an object. With an index buffer, you define your order using the index buffer. But index buffers are optional. Without an index buffer your order would be determined in the vertex buffer. Turn back face culling off for debugging, but otherwise you want it on.
Now that I think about it, some may find it useful to see my entire Python script collection. Like I said, the only way I could figure out Blender scripting was to just fish around and try things out. There was little to no instructions I could find on how Blender data is organized. These scripts are things I saved while fishing around that pulled certain types of data from Blender. I think there's some stuff in there for skinned animation as I see some references to armatures.
I wrote a program that extracted the animation data from Blender using the basic humanoid armature that is in Blender. I created the animations in Blender using the basic humanoid armature and then my script exported those animations to a text file. I then loaded the file into an XNA program where I played them back as stick figures. It worked. The stick figures moved just like the armatures in the Blender animations.
Looks like the code for that is on my website here:
http://virtuallyprogramming.com/XNATutorials/ThreeDTutorials/SecondTutorial/SecondTutorial.html
But it is an XNA project, not a DX project. Still, that should not matter if you are just interested in the Blender exporter. The Blender exporter should be the same regardless of whether it is XNA or DX. Wait, I was able to find what appears to be the Blender exporter to export the animations. I'll make that a separate post.

bpy.context.active_object.vertex_groups[0].nameHere is the Blender exporter for exporting skinned animations. Skinned animation takes more than this data. Namely, it takes the "skinning" data. That is, when you skin a model you are assigning vertices to a bone in the armature and when you weight paint, you assign the percentage that each bone influences the vertex. So, all that data has to be exported. I would want to export that data separately; I would export this animation data exactly like this and then export the model as a separate file which would include the skinning data to describe which bones the vertex is influenced by and the percentage weight. I never got around to writing that exporter unfortunately. Learning skinning and weighting in Blender will help understand how to write that exporter and use the data in code.
But this exporter worked to export the armature animation. And having the animation data separate from the model allows the animation data to be re-used on many models. So, a walk animation could be used on any humanoid model that uses the same armature. Since the humanoid armature in Blender is standard, you could reuse the data a lot.
