Problem whit the extrudion of a chair profile

Hello , i have imported from autocad a profile of a chair, that i plan to extrude it, But the problem is that it dosn't let me do this operation. Can someone, please give me any advice on what the problem is and how can i fix it? thank you
I attached the part/sketch so you guys can have a look.

You must go through the profile and ensure there are no gaps or overlaps in the profile. I exported to AutoCad and found several. You also cant have the lines dividing the profile into 4 sections. if you are using Autocad type overkill to remove any duplicate lines, delete the straight bisecting lines, then the pedit and join all the outer and inner profiles to create a closed profile. when all the gaps and overlaps are removed. (all lines joined endpoint to endpoint you will be able to extrude it.

the sketch is "bugged" - there are too many lines double- and connecting lines interfere: they must not be included!

usually I have with autocad no problems with sketchy - but rather imports in others.

Question: With a good design - a chair is an entity that is not tailoring of a large plate - but made up of individual elements.
So side parts (left and right), the head part, middle part.
I would build the design as it also has to be assembled later into reality.
the problem with the actual sketch if it is to be used (which many do so!) that one for point point - object has to check for object: the take - depending on the complexity of the sketch - a very long time.
The simpler way - and also the better (I guess) would be the real conditions on items that group.
then everything goes easier and faster!
For this reason, I would not use such sketches - but produce a set of simple parts- with integrated fasteners new!
just as a note.

I watch your sketch times on and ask if I can do it then an assembly in here: but may take some time!
have unfortunately - still important work.

Another consideration is that the sketch imported without many relationships. All of those curves will be difficult to work with later if they are not tangent. The current sketch has only six relationships. If you use the Fully Define Sketch tool, it will go through and add in a bunch of the tangent and equal radius relationships.
Considering that the sketch is symmetrical, I'd delete half of it, and only work on one side. I'd rather cut my work in half when given the option!

Detlef makes a great point about splitting the model into parts. If you leave the imported sketch as a reference, you'll be able to make new sketches with the convert entity tool. From there it would be easy to create the top, side, bottom and back components.
I've attached an example. It is in 2016, but I've heard 2015 might open 2016 files.

Hello there,
I'm working on the provision of a kind design methodology - ie: you should be able to recognize from the existing tasks, which way you tread must- to quickly and effectively - to be able to do a good job.
import - and export functions are unfortunately vulnerabilities with partially considerable potential for error!

Today we know that the 3D printing only reason not flexibly and effectively works because interfaces between them - obsolete from CAD to 3D printers, are inefficient.

between CAD programs that is up to today unfortunately so: they are quickly adapted by SAP interfaces as EDOs to needed - then work but insufficient!
SolidWorks is a great program: it is not there!
for daily work is therefore to recognize and to tread only darum- the best possible way .....
everything else means a lot more work!
So I do not steer well clear of sketches - because SolidWorks only sketches based work permit.
I avoid only what can be seen not repairable!
in your case, I just use the imported sketch - if a drawing can exit - to obtain mass to determine the part.
then I'll do it again!
I work with SolidWorks and with Unigraphics : if the first digital book of mine to design methodology ready Actual I translate it into English and put it here - hopefully I may - free pure for all.
Because in my opinion, needs to know to be free of all constraints, be freely available!
I do my job, and documenting it happens screen-shots: otherwise you can not detect and eliminate errors.
So fall of data that are better than many trainings.
so I admit that continue also free so that others may benefit from my knowledge!
others think differently so that's just!
