Calculate Area between Feature Lines

[SwChilly]

How do I calculate the area between feature lines?

Is there also a way to calculate area between a contour and a feature line?

How about calculating the area between two contours?

[Tyke]

Are you wanting the actual area of a 3D surface between the contours/feature lines, or is the 2D area sufficient. If you want to get the area of a 3D surface, you must create it and get its area from the properties panel. You could use the LOFT command to create the 3D surface. For a 2D area you need to create a closed polyline and get its area from the properties panel.

 

That's a couple of suggestions, no doubt someone else will be along with some more.

Like Tyke if you export out the surface as 3d faces there is lisps that will give you true 3d areas. Remove the z and get 2d answer usefull for grass coverage.

 

Most of the stuff like feature lines & contours can be exported out to simplified plines etc and then manually you can get areas, use the "boundary" command its like hatch but produces a pline of an area then can get area from properties.

What I would do for feature lines is:

 

1. Create a new Surface.

2. Add the Featurlines as Breaklines to th Surface. (Just the two you want to find the area between).

3. In Surface Properties > Statistics > Extended it will displaye the 2D Surface Area and 3D Surface Area

 

For the Contour Lines:

 

1. Extract them from the Surface. Produces a polyline with Elevation.

2. Create a new Surface.

3. Add as Breakline.

4. Look at the Surface Properties to get your information

2d> command :boundary / and then properties [as helped uphere]

or use fields to make a dynamic table
