Shankar, the ANSYS members on this site don't open attachments like Parasolid, but independent members like me do open attachments.  You can't attach a Parasolid directly, but you can put any file type into a zip file and you can attach that as long as it is < 120 MB in size.

To get the best help from all members, it is better to use the Insert Image button and select an image file that you have saved on the disk from a screen capture program like Snipping Tool. If you paste the geometry into Powerpoint, you can annotate the image with some text and point to relevant features, then do another screen capture of the Powerpoint page, save that file then Insert that image into your next post.
