Hi, PPM, I'm going to echo PMUNDY's previous reply to "check out Harken-Reidar," but I promise not to advertise . . . we (Harken-Reidar) are an authorized Bentley Channel Partner reseller and Certified Bentley Institute training partner, so you actually can get Bentley products from a practicing engineering and survey firm. It's no longer necessary to purchase directly from Bentley.
Someone suggested Power Survey, and this is indeed the product of choice for your stated needs. It is sort of like Carlson's "Embedded AutoCAD" survey product in the sense that it is built on Power Draft (the Microstation CAD Engine) and does not require a separate purchase and installation of the full Microstation package. The nice thing, though, is that it does allow all the standard Microstation tools and add-ons with the exception of the solids modeling (teapots and gears, etc), but also adds the powerful Survey module tools like those found in InRoads and GEOPAK. There are also some other interesting alternative options you might want to consider as well.
We'd be glad to help you out, just give me a reply, or to my business partner Harry Ward at
hward@harken-reidar.com (one of the primary bloggers and contributors here).
Good luck!
