Problem with exporting obj document

[Anonymous]

Hello!

I have one problem with this drawing.

I have worked with more than 50 drawings and the steps after finishing the ipt of every single one, are: 1)creating a dwg with mechanical drawings, 2) export it as an obj document, 3) run this obj with  an android app (which use is to scan a mechanical drawing and show the object in a 3D environment).

It is a great app developed as a thesis for an electronic engineer student and hasn't show any errors since now.

So, after the long introduction, my problem is that, when I create the obj document of this part and I run it with the app it looks like the pic below. It doesn't show any blade of the propeller, only the cylinders ("turbines"). But when I run it with a pc app like "3D builder" it is perfect. I haven't faced any problems like this before with other parts.

Also when I try to derive it to an other ipt it shows a lot of errors. Do you know what could be the problem here?

Hello,

Sadly i'm running an earlier release of Inventor so i can't open you ipt file.

However, if the file is importing on a PC program perfectly, i suspect it has something to do with the android app.

Hopefully someone else can open the file and confirm whether it's been modeled correctly or not.

Hi! It is unclear to me where the problem is. Attached is the mesh file and the imported mesh file. I am not seeing any issue. It sound more like an importing software's issue.

Regarding the derive error, please share the steps to recreate. I would like to see the failures.

Many thanks!
