List area of hatching lisp?

Does any have or know of a lisp that gives you the area of hatching by
selecting the hatch itself (when no boundary is present)? Or is this type of
thing not possible in AutoCAD?

Detail:
I have a series of hatches on a map drawing, which depending by color
indicates road, building and other. The engineer wants me to tell him the
square footage of each group (ex. total square footage of road, total square
footage of building). We received this drawing from a the client. There are
quite a few hatch areas (tiny, small & large) all without boundaries. I can
freeze all but one of the hatch area layers. I'd like to be able to select
all the hatch and have AutoCAD tell me the total area of the selected
hatched areas ....if it is even possible.

I have tried looking for a lisp, but no luck

Thanks for any help in advance

 

Hi Jeff,

Try HatchB, from www.jtbworld.com,
this lisp will recreate the hatch boundary, and after that you can obtain
the area of the plines

Jeff,
I do not think there is a direct method to get the areas covered by hatches.
Did you try to read any extended data that may have been saved with those
hatches?
If you do you may notice something like (72 . 1) (10 23406.8 -7387.89 0.0)
(11 26040.1 -7387.89 0.0) which defines one boundary. I am not sure if this
dependant on the way those hatches were made. However that is a boundary
which you can assemble it with other boundaries and create it then read its
area.

Nabil.

Hi Jeff,

If you are willing to consider a third party tool, there is a solution
to this in our GeoTools program. The GT_HATCHBOUND command re-creates
hatch boundaries from hatch objects as closed polylines. The area of
these closed polylines will give you the area enclosed by the hatch object.

You can download a eval version at this URL:

If you need a more tweaked solution, email me with more info.

I already have a routine that does what your saying. I was hoping to save
time by eliminating the steps of boundary re-creation then listing them
individually. It can be very time consuming to re-boundary 40 or more
hatches and then list each one for the area ...then add the areas together.
I was hoping there was such a monster that would give you the area of the
selected hatches ...a one shot deal.

Thanks anyway,

Have you tried hatchb.lsp from my site? You have to get the latest version
that is online there. The total area is returned even if you select multiple
hatches.

IDM is an excellent downloading program
That is the best downloading program I ever seen. I just became a
'download-maniac' after the use of IDM!!
