is there any possiblity to convert the Polylines containing object data to a 3D Solid so that the object are also copied?
I'm not sure to understand that in detail.
To convert a Polyline to a SOLID (with commands like _LOFT, _EXTRUDE, ...) will not transfer the object-data from the polylline to the solid. Never, at least never without development.
However there is a sysvar DELOBJ (for details look >>>here<<<) that controls if the polyline will be thrown after convertion to SOLID or will be kept in the drawing-database. And in case the poly will not be erase, you will have at least the original object and attached to that the origial ObjectData.

Trivial workaround: instead of extruding those polylines, change their values of THICKNESS.
It won't be a true 3D (I'd call it 2.5D) but you'll keep the Object_data...
That's what I have done in the first step. I am creating the 3d buildings out of their ground polylines. I have to keep the object data as I need to connect the created 3d buildings to the database afterwards. The ID needed for the correction is stored in the object data.
That's what I have done in the first step
Sir, in the first step you were talking about "3D solids" and not about "thick polylines"...
If your database contains the height of buildings, you may give automatically thickness to them, by means of a "draw query".
But remember (I repeat it for the second and last time): the final effect will be 2.5D and not true 3D.
My first question was about the whole problematics.
What I have already succsefully done is the "thickness" solution. But it is not what I need. I know you can make it better using some hatch with elevation but I really need those "boxes" as buildings. And the only way I have found to create them is to use the _convtosolid on the polylines with thickness. The created building solids are exactly what I need. But they lack the object data. Therefore the question...
It looks like I will write some little app to process one polyline after another so that I can also copy the object data after each conversion.
I don't believe in miracles, but if you'll really make such an application able to "inject" Object_Data in 3Dsolid, we might pay for it, sir.
By the way, when someone needs from me 3D effect with full GIS information, I convert my DWG objects in KMZ format file, to use only in Google Earth.

Let us know what you need. I don't see a problem to combine an extrude-command with copying the ObjectData. That's done within a view minutes.
The flexibility of such a tool may explode the dev-hours. So for example what command do you use to create 3D-Solids out of 2D-geometry holding ODs? (LOFT, REVOLVE, ...)
Second questions raises up when you not only create 3D-SOLIDS but you work with them ... so what sould happen if you subtract or intersect or do a union-modification ==> what should happen to the OD? Should they stay on each history-part of the objects or should the OD of the first SOLID stay and from the second one should be removed/erased? Or (I'm afraid of) should both OD-records ba attached to the resulting 3D-SOLID, what's not valid out of rules of Map3D?
Give me some input (wishes, specs), the weekend comes up and there may be a few hours left

Hold your horses, gentleman, I think this is not a commercial forum...
In the meanwhile, I suppose that Mr.Maherich would be interested by your offer.
If you say that's an easy thing to accomplish, I will try by myself.

Have I said anything like "you have to pay it"? As long as there are just a few minutes or it's just for fun (because of very interesting ... or I do need it for myself ... or ...) I dosometimes things without sending an invoice

To attach the data ... yes, to handle the ODs during SOLID-modification-commands ==> exciting, but IMHO not as easy
