Hi i need help

hi i´m new and i need help with this rims i´m trying to make in 1/24

this rims made are made by me the program is zmodeler 2.
NOw i´m getting again the computer where i had the 3ds max repaired so could someone help me step by step??

What is it you need help with?

well like i said (i think) i want to upload this rim to shapeway but when i try to upload it looks like these

and i tried to upload it in different format and always get forms like that
so what could i do to repair it and to upload it well???
the rim how it looks:

Zmodeler and 3dsmax are doing a poor job with the boolean operations.
If you will save the file as an STL, and then grab a copy of Netfabb Basic from www.netfabb.com
You can open the file and see that around the edges there is a yellow line (hole in the model)

You can attempt to fix it in Netfabb, but often you're better off fixing it in the original program you drew it in.
But, Netfabb at least shows you where the problems are..

In case you don't know the steps to repair the model from here, check out this tutorial:

thanks for the help but i dont know how to continue here you have how it looks when i start working on netfabb

how should i start my next step??

As Stony said, those yellow lines are holes in your model. When you upload, our software heals the model, but it doesn't know how you'd like it healed. So it closes the holes the way it sees fit. In netfabb, there is a heal function. If you close holes, you'll probably get the same results as your shapeways upload. I have no experience with your software to be able to help you create a closed model unfortunately.

So, isn´t any solution???

There is a solution.
I replied to a thread on how to fix problems like this but I can't find the link.
Pick the 'Add triangles' icon in Netfabb to fill the holes in a way you want.
Send me the file by PM or my email below if you get stuck.

thanks i´m trineg to dothat part by part i will see if i can finish it

well, i repaired most of the yellow parts

how could i smooth the file???
with meshlab or netfabb basic or similar programs???

File fixed

thanks!!!!

Does someone know how could i smooth the triangles of a rim without nefabb?? i say it because i got the basic version and asks to smooth thepro version so in any program to smooth triangles???
