Turn 2D draw from AutoCAD into 3D model

[Anonymous]

Hi everyone

Meaby first I precise what I want to do:

1. I draw my 3D object in AutoCad, in 2D form (I prefear to trasforming photos into CAD draws)

2. Now I want to import my .dwg file to Maya 2018 (which do not make me a big problem)

3. After succesful import I have got just a curves in Maya; so I am thinking about extrusion of my curves and later transform it directly into 3D figure. Or I can turn my curves into polygon and then tern it into 3D figure by extrude.

4. When I finally turn draw into model i will shape or sculpt it as i want.

5. Printing ready model in 3D printer.

I am putting the results of my work:

Auto CAD drawImported draw and I made a grouping of curvesResult of creating a planI do not ounderstundEffect of excursion

So the problem is in 3-rd point. I try to make so by both methods but I do not menage to make it done.

I am a begining user of Maya So I please for help and advices

(I am sorry for my english but this is not my thirst language)
