Actually I Have Assembled Radial Engine But i Have a problem regarding mechanism creation of same so please reply as soon as possible....
first off: You havent included the parts. If you want to upload your assembly, you should select file --> save as --> save a backup.
This will make a copy of all files to a specific directory. zip this and upload.
Second: What is your question? Do you want others to fix your model for free?
Or do you have a specific problem you need help with? PTC really lacks providing decent tutorials but you can find great tutorials on: http://sharptechdesign.com/Tutorials/Mechanism_WF2/MDX_WF2_TOC.htm
(not compatible with the chrome browser).
actually i want specific constraints information means for which part which exact constraint must be given to run the mechanism...
Have a look at this: http://books.google.nl/books?id=bq-KmkRFJTAC&pg=PP1&lpg=PP1&dq=Mechanism+Design+with+Creo+Elements/Pro+5.0+Pro/ENGINEER+Wildfire+5.0++By+Kuang-Hua+Chang+Ph.+D.&source=bl&ots=5l6HO4aLZD&sig=iR-EPu49_yUNbmz0IsQT6rsuTLQ&hl=nl&sa=X&ei=pHqOUrLiGMTBswbXgYHwAw&ved=0CDcQ6AEwAA#v=onepage&q=Mechanism%20Design%20with%20Creo%20Elements%2FPro%205.0%20Pro%2FENGINEER%20Wildfire%205.0%20%20By%20Kuang-Hua%20Chang%20Ph.%20D.&f=false
And for the official PTC documentation Google for: "pro engineer wildfire Mechanism Design and Mechanism Dynamics Help Topic Collection"
