DXF Editor: Ortho On/Off

The "ORTHO ON/OFF" feature is very useful for preparing flood profile tables in the DXF Editor program. This feature allows the user to restrict mouse movement orthogonally, making it very easy to create or move lines or text perpendicularly aligned to a profile grid. Double-clicking on the Ortho On/Off text box in the bottom panel of the editor window toggles between on and off states.

DXF Editor: Draw Tools

There are several DRAW tools within the DXF Editor program that can be used to insert graphical details and callouts when creating flood profiles. The most common DRAW functions are Line, Polyline, Arc, Circle, and Text which can be accessed from the left toolbar. The DRAW menu is also a standard main menu listed at the top.

The following descriptions explain what each DRAW tool is capable of and how to use its specific features:

Line

Draws a line or series of independent lines using the mouse to click endpoints.
