Tinkercad export to Fusion 360 is faulty

[tb50000]

Hello everybody reading,

Im not sure if this is the correct forum but Ill post my issue anyway, before I got in touch with fusion 360,

I designed a fin-like object in tinkercad it looks like this

https://www.tinkercad.com/things/aw5u6nrc05U-fin-mx-218-v2

Now I tried to export it to fusion 360 bcs I need to put it on a design I then want to put in CFD.

But only a small fraction of the object got exported

(Yes it has a triangular hole in the back)

Now my problem with using the .stl file is that fusion breaks it down in very small surfaces, as it does it with any mesh, and this creates a lot of problems in further usage (like putting in in cfd) 

Could anyone pls tell me what options I have if I dont want to have an object with countless small surfaces which are hard to use as objects?

Hi,

If you downloaded the model as stl, the appearance is normal.
Use a neutral format, such as STEP.

Hello Günther,

thanks for your reply. I was writing about this feature. I know importing an stl file gets messy results thats why I tried using this feature. I dont know why I appended the .stl file.

when I wrote my case I missed some information which helped me solving it. The body consists of the fin and a bottom plate. This bottom plate was cropped out from an .stl. which I imported into tinkercad. Thats were the issue is. Now when using the "send to fusion 360" feature, every step which involved this cropped out, imported bottom plate was falsely translated. 

What I did was I uncombined the fin, imported the bottom plate, cleaned it up by merging some surfaces and then do every step what I did in tinkercad in fusion 360. That did the trick.
