Doug, If you don't want to spend any money on this you can do it with a little effort in geosoft. Since your desired line direction is EW its fairly simple, angled lines would require a little more effort.
1. Create a new line with an x and y channel. Make the y's equal to some rounded minimum value and the x's such that they span the entire polygon. 2. Copy the line however many times you need to and apply the offsets to the y coordinate. This is the painful part, if there a bunch of lines you could just define an offset channel and use y=y+offset*200, or similar, to create the new y's. 3. Make a distance channel. Its under channel tools. 4. Refid your database (Database tools|Database Utilities|Re-fid to distance reference). The reference channel is your distance channel, and your fiducial increment is the station spacing. 5. Window the gdb to your polygon. (Database tools|Window Data|Window X,Y to Polygon mask. There's lots of variations on this theme. For more than a couple of lines I would replace step 1 & 2 with Excelliness. cheers, Marc Marc Pelletier, P. Geo.
