Win32 and 64, English

Meteorowl OÜ
Plugin for calculating total lengths and total areas of polylines

General Usage Instructions

There are two ways to create MeteorSpec LT objects:

1. Polylines with data are located right in the project drawing on a separate layers,

2. Polylines with data are located in a separate dwg-file, and the project drawing is attached as an external reference.

You need to create the required working layers of the program, if it's not yet available in the drawing. This may be done by one touch of a button in the window "Drawing Units and Settings". In the same window you can set individual measurement units for the edited drawing. 

Polylines for total length calculations should be drawn on the layer "meteor-spec-lt-length" and polylines for total area calculations should be drawn on the layer "meteor-spec-lt-area". 

Three steps to the finish:

1. Draw the polylines in the work layer of the program, repeating the routes of those communications or surfaces, the specifications of which you need to calculate;

2. Assign the names and descriptions to the polylines using the command "Object Data". The window "Object Data" gives the full access to the Data Library. If you need, You can any time change something in the Data Library through the window "Edit Data Library";

3. And finally, with one touch of the button for the command "Total Length Calculation" or " Total Area Calculation” You may print the table of results right into the drawing.

Actually, that's all. If you later need to change your project, then make changes to the MeteorSpec LT model and you will immediately get a new table of updated results.
