When working with customizations which make use of information from Windchill PDMLink it is sometimes helpful to be able to generate e.g. the URL to a detailed info page of an object by providing the objects internal ID.

Windchill provides several helpers:

URL Example:  http://servername.com/Windchill/servlet/WindchillAuthGW/com.ptc.wvs.server.ui.ThumbnailHelper/#helperMethodName#?oid=wt.epm.EPMDocument:139194

In the URL you can replace #helperMethodName# with one of the following entries:
getMThumbURL
getThumbURL
getThumb3DURL
getDetailsPageURL
getHelpURL
getPVLaunch
getPVS

When sending a request to this URL you get a new URL in return which points to the required object page. This is much easier since you don't have to do string processing to generate URLs.
