This site is the source for the HawsEDC Free Software (see license below) tools, including this newly released in 2015 Site Grading and Drainage Plan Designer, a powerful 3D design tool like AutoCAD Civil 3D Feature Lines for site grading. I invite you to try out any of the tools here that interest you and to tell others if you find the tool valuable.
Please leave feedback if you can to let me know this is being enjoyed.

When you want to design the grading for a site without a calculator, you need a tool like AutoCAD Civil 3D Feature Lines or Grading and Drainage Designer so you can set the elevations of points based on other points, see the slopes between them, and make adjustments that are reflected in the appropriate slopes.

If you are trying out GDD for the first time, open the gddtest.dwg drawing to get a feel for what GDD does. Note that GDD creates the following objects in your drawing.
Note next that GDD has a pull-down menu. Start by choosing "Insert Single Point" (IPS keyboard command) or "Insert Double Point" (IPD keyboard command). Follow the prompts to insert an elevation point. Note that you while gddtest.dwg is centered around elevation 1250, you should enter only 2 digit elevations because that is the convention for this project as shown by the points already present. GDD analyzes the drawing design to determine that the typical elevation of the gddtest.dwg drawing is about 1250 and the display elevations all drop the 1200.
Choose "Single Point by Slope" (IPSS command) or "Double Pointby Slope" (IPDS keyboard command) from the menu to insert a point at a reference slope from an existing point. If you don't want to choose a location for the slope arrow, choose "Prompt for connector placement" from the menu to uncheck it.
Use the menu to Raise/Lower or move one or more points or Edit Elevations.
If you can't see in your AutoCAD window the helpstrings that are provided to explain each GDD menu command, refer to the list below.
