Polyligne overlaping , ans missing "spot"

[joh_richard99]

Hello,

I need your help

I have drawings that all feature a large area (A) on layer Principal. This area is subdivided into several smaller zones defined by closed polylines (b,c,d,e, etc.) on layer Other. Theoretically, if the total area of (A) is 20 square feet, the combined area of the smaller zones (b,c,d,e, etc.) should also total 20 square feet. If the combined area is less, it indicates gaps between polylines; if it's more, it suggests overlapping polylines. A combination of both issues can also occur.

When I working with fewer than 10 polylines (b,c,d,e, etc.), manual verification is manageable. However, when the large area covers 30,000 square feet and is divided by 150 polylines, the task becomes more complex. I don't know where to begin to find error detection in the drawing. VBA, LPS...

Thank you,

P.S.: I am working with AutoCAD 2022

Interesting. How would you know that a given closed polyline is 'correct' v/s 'not correct'.

Example: 100 sq.ft. in A, 20 in B, 20 in C, 22 in D, 19 in E and 18 in F (total 99).

You would know that it isn't totally correct, but is C too big, or E & F too small, 

and if E & F are both too small - which one or both ? .... on and on.

I'm getting a head-ache.

There is in land development tools for drawing polygons based on an area input, they have various options, like swing bearing, parallel side and so on. May be worth looking for them. Check out CIV3D & Civil Site Design as a couple of suggestions.
