But, it's "free," or even "inexpensive." If you want direct translation of Pro/E files into other formats, the best tool I've encountered is something called PolyTrans. http://www.okino.com/default.htm I bought a license for NuGraf (which is polytrans plus a fairly nice renderer... not as full-featured as Maya, which I use, or 3DSMax, but very nice for "photorealistic previewing" before going into Maya for rendering) a couple of years ago, now, and I've never regretted it. You need to buy the "Granite Pack" to get direct Pro/E file translations, by the way. It's all spelled out pretty clearly on the site. On the other hand, you can always just export/import in .OBJ format...
