How to upload rendering file?
One good procedure for uploading rendered files
-Upload the regular files
-Click "renderings" ( Its just the Model feed & Revision buttons)
-Go to the "select file" box (on the bottom) and click the "Browse" button
-Pick the file that you want to place and click the "Open" button
-Then click the "Upload" button
After that you should be done.
I would agree with Ali. I usually use Inventor software and in Inventor there is an "Enviorment" part, in which you would use the Rendering. When you use this Enviorment section there is a part where you can automatically save the files. Most of the files are saved as JPEG or Bitmap format.
