Three Questions

You are in luck. I had a bit of time, and I also wanted to refresh my 3D mapping skills somewhat.  

First off, I looked through some texture pwads for a suitable archway texture and found it in Gothic.wad.

Uarch_texture.wad

Next, I made the archway with 181:plane_align.

Uarch_slope.wad

While those probably will do, they are a bit basic.

Next, an example of a rudimentary 3D archway,

Uarch3D_slope1.wad

and the lower arch rounded

Uarch3D_slope2.wad

and last but not least, a proper archway

Uarch3D_slope3.wad

because of the complexity of the 3D constructs, I used boris's 3D plugin which makes mapping 3D sectors a breeze.

Since you seem to be targeting the ZDoom family you can use UDMF to flip textures. To do that you have to set the scales of the texture to -1, like this:

All of those can be accomplished with an advanced sourceport.

ZDoom, GZDoom, Eternity, etc.

I use GZDoom.

A) How do I make the perfect arch, round and nice?

Either use a patch of an arch and attach it to 3 linedefs,
two sidedefs set to impassable for the sides and one upper

sidedef for the arch top.

Or do many sectors using slopes, with upper sidedefs.

The more sectors the smoother the arch.

Using the 3D mode in GZDoom Builder-Bugfix makes adjusting the slopes very easy.

B) How do I make a 3D-floor move sideways, not only up and down. Like a polyobject...

Use many 3D sectors, similar to an extending bridge

C) Can I rotate the texture of a wall or make it up-side-down or mirror?

That can be done with ANIMDEFS  and TEXTURES, using many images. Again, the
more mages the smoother the animation. Some simple scripting may be required.

Merry Christmas and a Happy New Year! :)

I think you will have to make some examples to make me understand. ;-D

hm where might this 3d sector plugin be found? And is it compatible with gzdoom builder bugfix?

On boris's github page, or check out the thread on ZDoom forum

Of course. Just make sure that you install the correct version,

for x32 (140 KB) or x64 (152 KB).

If you are looking to flip/rotate a texture for static use in your wad, you can use Slade3 to make flipped/rotated copies of the desired textures.

Oh my, this is interesting. Good to know! @boris
