How to emboss or extrude a logo or image

[jb.zijp]

How can i emboss a logo into a part/sketch? I use inventor 2015. I managed to convert the jpg to dwg. Now i have the outlines i need. But when i want to extrude or emboss the shapes i can only select the lines and not the area's. Should i join the lines first ore something? Hope someone can help me. I searched other topics but none gave me a good answer besides tracing the lines one by one but that would take too much time and won't be as good as the original.

Here's an acceptable result after only a few minutes of time.

Perhaps you don't read or don't get my problem !

WHY ON IMPORT INVENTOR SPLIT big splines/arcs VECTORS ON SMALL PIECES !?

You only focus to find trouble on my file ; and did not answer at the main question.

And for your know, this is not the single example, I have many of this already had, this file perhaps have accidentally 3 rows of vectors at the time, but I try many other importing with same results, and with many third party softwares, aspire,rhino5,corel.....

Maria, the problem is made by the existing DXF.

See the number of points, when opened in Rhino.
