I need to draw polygons like a "dash line" in Global Mapper (GM). It is necessary that the polygon has beats and spaces between the dashes.

GM has a style for lines with dashes, but it's for lines and I need create polygons.

Maybe there is an option to convert the line style to a polygon?

I am using Global Mapper 16.05.

In Global Mapper you can easily have a polygon with dashed border like this (see sample in the bottom of the dialog box)

enter image description here

And/or with diagonal cross-hatch like this

enter image description here

If you select white as the fill-pattern color, it will look like this

enter image description here

However, you can't control the thickness of the lines, so there is no way to make it look like in your drawing.

However there is a workaround, by creating lines and then coping them to the polygon, for example I can create a line like this

enter image description here

And then create 20 lines perpendicular to it by right-clicking on it and selecting "Advanced feature creation options -> Create Perpendicular lines spaced along selected Lines/Areas features..."

enter image description here

If you choose a very large line thickness for the newly created lines, they will look like this

enter image description here

Then we delete the original line, select the polygon and right-click and select "Crop/Combine/Split functions -> CROP - Crop loaded features to selected area(s)..."

enter image description here

In the dialog box select to crop lines and the checkbox to mark as deleted the cropped features

enter image description here

The result should be pretty similar to your drawing, in my example it ends up looking like this

enter image description here

Or like this if you select to use flat endcaps for the lines

  • man, you are cool) did a little differently: drew a line and created perpendicular lines with an interval. Then I selected the "perpendicular" lines and created a buffer for them. After - removed all lines. I got the result what I wanted :D i.stack.imgur.com/poy4g.png
