I have tried DoulbCad, DC 1 the first version and the update DC 1.1 and found both lacking.
I originally bought TubroCad14-Deluxe Upgraded to 15,total cost $150 US. However TC 15 had some quirks that made it frustrating to use. Like three key click to start and finish each end of a line if you had any of the snaps turned on.
So I downloaded DC 1and found that some of the quirks in TC15 were gone and there seem to be an improved interface. So I started trying to use DC 1.
DC 1 seem to stop for no reason, requiring me to close and start again. And the start up screen would hang up at 99%, preventing the program from starting. All very annoying.
However, after trying to work with it, I found the documentation weak; some items just didn’t make since on how they were to work. The documentation would show screen shots that did not appear in the program. Just try editing a multiline text element. So I downloaded DC 1.1, the update.
In DC 1.1 the start up screen always has closed allowing the program to start, documentation did not change; and I can say there were some improvements. A nice program for free. However it still had some quirks that I found time consuming.
I noticed that TC 15 had a new version, TC 16. So paid the upgrade price. Now TC 16 seems to have taken the best of DC 1.1 and greatly improved from TC 15 in some other areas.
Improved drawing with snaps on. No more unnecessary mouse clicks jus to draw a line. To me TC 16 is well worth the money. Even if DC 1.1 is free, my time isn’t, so a free product that cost me undo labor is not free to me.
An on a personal note, I had a person at DC email me and set up a phone time to talk about the program. So I set home waiting. No call.
So it is almost a good product for free especially if you have no time constraints, however, if you want to truly good program to make construction document out of, try TC 16.
