I attended the webinar on SurvNet. Yeah, the guy from C&G wrote the software and he moderated the webinar. It allows for total adjustment of all points, sections and measurements. So much so that, if you do not really know what you are doing, you can force a closure that may not be accurate. Our surveyors are not totally sold on it yet. Many of our clients want us to show the precision of closure on our surveys. SurvNet did not give this information initially. We requested that this be added, but I do not know if that has been done yet.
Carlson software gives the surveyor pretty much the same tools as LDD. In some areas it gives you more tools. BUT as I have stated before, it appears, right now, the software is designed for Surveyors, but does not have everything a picky drafter will want. There are compromises and work arounds to be discovered. It's an ideal package for small operations. If you are running the gun during the day and drawing and stamping plats at night, this is your software. The price is right and you will have the tools you need.
Am I in a rush to give up my LDD or Civil3D? Not just yet. They are adding to their package everyday and are responsive to customer request. They will soon be the new "Softdesk", which, IMHO, was the penultimate survey software that AutoDesk purchased and ruined. Had they given the lead to the Softdesk guys for their survey package we would not be having this discussion.
You also have to evaluate costs. The standalone package is less costly than LDD. I think the pack on Intellicad may be too, but I have not really looked at the latest price sheet.
Right now, the software is a "Viable option". They have full Civil packages, mining packages and a whole bunch of other stuff available. I am just playing with the Survey part. Both packages have their pluses and minuses. Get the demo discs. I am trying to get a real Carlson guy to come on this site and field your questions, comments and concerns. It would be better to get your info from a Carlson guy. Not saying that I would lead you astray, but...........................
