Landmark is an easy to use CAD software that is compatible with other CAD programs, which allows for collaboration with other professionals, and also has great rendering capabilities to generate legible plans. Great tech support, too! The program is set up differently than AutoCad, but once the structure of the program is figured out, its fairly easy to take it from there. Importing other files types has been easy, too, such as adding aerial photos, pdf or jpeg images as backgrounds and supplemental information on the sheet. Its nice to be able to lay everything out in one program and be able to seamlessly update the plans as changes are made.
Getting other CAD files to import properly can be challenging. CAD blocks need to be exploded to get the basic line work to be modified in some cases. I have had some issues with large files crashing, but there are a lot of program updates that keep the software working and compatible with other software.
Give it time to learn the software and utilize tech support to help figure it out. There was a steep learning curve at first until I figured out the organization of the program, but from there its mostly intuitive.
Landmark tools are really easy to use to draft and design. Even the basic tool set allows for a lot of flexibility in designing even organic shapes and hard geometry. There are a lot of options to render drawings- adding transparent hatches and colors to add texture and value to an otherwise black and white drawing. The sheet layers and view ports work really well for creating and managing multiple drawings for complex projects.
