workspace "basic cad operations and mouse behaviour".


Init Drawing

The first time you use AirNavCAD, you are going to see this figure, you have to click on Drawing to start workspace.


Init Folders

Now workspace appears, if you click layers you can extend the layer component. Now click on CoastLine and the folders on appStream are been created. Now you can update the CoastLine and work with the program.

There is a worldwide coastline that is given with program but user can update with other.



You can change the background of the workspace, in Tools/Options: Appearance/Background.

For user eyes, black background is better. So you can change it.

Draw Elements


Now we are going to show you the elements you can draw.

  1. Draw Polylines

  2. Draw Points

  3. Draw Lines

  4. Draw circles and arcs.

Is very easy. The output tell you what to do and even gives tips to do things with elements.

So if you draw a polyline you can draw in workspace directly or use the command line with points (if you know them) in the format x,y,z:

except the last one point that not get : 




Click on any place in workspace, paste the points in the command line and pulse enter (inside command line), this way you get polyline with points.

This is good if you got a lot of points in an document and you want to draw them on the workspace.

Basic Operations

Select elements.png

Now we are going to show you the basic operations.

  1. Extend to intersection (only lines)

  2. Draw Parallel (only lines)

  3. Extend workspace to the limits of drawings (very useful)

  4. Join in Close Polyline (join lines, polylines, arc in one close polyline).

  5. Join in Open Polyline (join lines, polylines, arc in one open polyline).

  6. Move vertex of Lines and Polylines.

  7. Insert vertex in Line and Polyline.

  8. Copy coordinates in 2D of Line or Polylines in a TXT format to paste on another cad program.

  9. Copy coordinates in 3D of Line or Polylines in a TXT format to paste on another cad program.

  10. Cut intersections.

  11. explode polyline in lines.

  12. Length size.

  13. Extend one line up to another element (polyline, line, circle, arc)

  14. Delete element

  15. Simmetry of elements.

  16. Rotate elements.

  17. Select elements with rectangle (left side only intersect, right side only inside)

  18. Select one element by one.

  19. Copy elements.

  20. Move elements.

  21. Pan Elements (also you can do it with middle button on mouse)

Is very easy. The most important thing to do basic operations it's that you need to select the elements before start the operation. Except join polyline 2D, 3D and Length size.


Join Polyline

Imagine you get a spiral wind a line a polyline for a vor etc and you need to create an area to obstacle analysis after. This is the main use of Join Polyline, join elements from workspace (arcs, lines, polylines) in a one polyline that appears in green color and in a new layer called joinPolyline.​

Just click in the Join Polyline button and start to select the elements with the circle helper anc click Esc to finish the process.

Also if you get a circle you can apply join polyline for using in obstacle analysis later.

Also you can use Join Polyline open to not close the new polyline and its useful for create Tracks.


Change layer

By default if you open a drawing the layer 0 is the active layer.

You can change it adding another layer and check that layer as active in properties of the layer (clicking with right button on the layer's name).

So when you drawing, you draw in that layer.

You can change elements to another layer.

  1. Select the elements you want to change layer.

  2. Click on "Layers" literally click on that name.

  3. Finally click on the layer name you want to change that elements.


Mouse behaviour

Middle button:

  • PAN (while your doing another action this function doesn't work)


  • Zoom

Left button:

  • draw, select, do actions

Right button:

  • snaps if click near another element.

  • Select one element if there are severals selected.



Save the workspace as .lcd : Click on file/save or icon of disk.

You have to wait a message that appears in the middle of workspace that inform the data has been saved. Make sure you get this message.

Also if you close drawing an alert display in middle of workspace asking you if you have saved you work before. If you have not save your work we recommend click cancel and then save the work.

If any Layer contain "shape" or "reference" in name Layer (you can edit name) it can delete directly even if there are elements in that layer. (good trick to delete stuff quickly).



you can open an existing file .lcd (the natural format of AirNavCAD).

Also you can open a .dxf format (DXF 2000) or even if you have already created a new drawing you can open a .lcd or .dxf and it opens on your current drawing adding new layers and that layer's name ending with Reference.

AirNavCAD is a tool to draw pans ops areas and help you to analysis obstacles. It only can open DXF not DWG or DGN but you can convert it to DXF2000 with others programs.


Short Cuts

you can edit and put you short cuts in Tool Options KeyMap

and can edit and put the short cuts for any operation you want.

you can export and save you shortcut with ManageProfile, export and xml file is going to be created for load if for example you admin update the program.

For example with Ctrl+A you can select all visible elements on layers not locked. Use can edit an use his own cut shorts.
