I became a designer prior to the proliferation of CAD programs and hand sketched everything. TurboCad was my first introduction to using CAD programs in 2006, and, after looking at other programs that had more features, I have always decided to stick with TurboCad. I don't have a need for a lot of 'bells and whistles', and, I need a quick turn-around time to get the designs in my customers' hands.
The libraries that are included are quite substantial, so, it can be used for many different applications. I mainly use the plant libraries, as I do landscape design, but, have used a few of the other libraries for different purposes.
I also like that I can do layers on the page, and, with a few clicks, be able to differentiate between the different aspects of the drawings. I have only needed to import AutoCad once, and it was effective.
When I want to save the document as a PDF some of the items are shrunk a bit, and, it puts the drawing on the 2nd page of the PDF document, leaving a blank page in front of it. To avoid this, I print out the page on my oversized printer and scan the document to create a true PDF.
This is a good sturdy product, with good technical support. The price point is very good, as well.
Because I do work for several branches in different cities, I am not always able to be on-site when a landscape installation is be done, and, our crews can rely on the scaled drawings without me. Design time efficiency is my biggest benefit. It is much quicker to do a scaled CAD drawing than to create a scaled 'hand' drawing.
