analytical subdivision of areas

[henry85]

Good morning to all,
I hope to do everything right because I am not at all practical of forums.
My problem is this: I have an area (in sq m) formed by an irregular poly-linea and I must demonstrate by simple geometric calculations how much the value of the total area is. to do this I must divide the area into simple geometric figures (triangle, rectangle, trapeze), numerarle, insert the quotas and calculate the area of each single figure: the total will be the value of the entire area, all reported in a table.
My question is this: Is there an application or a command of autocad, or a software that can divide into simple geometric shapes a very complex irregular figure? and maybe calculate for each form his own area?to have the solution for this procedure would help me to shorten the times that require an analytical study of an area.

Thank you!

I don't think there's anything like that, but maybe This is Could relieve you of work.

Thank you gp, I might be useful!

eh dear my gp, you gave him a hand but you are actually submitting henry to the insidious danger of errors.
his prof wants to see how he divides the areas (the more or less efficient way of finding subdivisions) into known and simple geometric figures.
the label area although the shortcuts of much work, exposes it to two risks (students):
one is to forget to divide some piece, but to calculate it the same.
the lisp is not limited to simple geometric figures, it could calculate the area of a paraboloid cut by an arch not passing for any of the fires, without beating eyelashes. and he clicking in the area wouldn't even notice. . .
two is that his prof (if I were the prof reasoner so) expects a "tolerance" between the real area and the geometric one obtained, both by approximation in measures (he asked for quotas...), and by subdivision (which will always leave residues).
he goes from the prof, tomo cuckoo, and brings the precise area to the 3rd decimal. and get a sound 4:wink:.

this without questioning your sincere desire to help him (know as you are), but as an aspiring subaiutante geometra I must point out these insidious implications. :finger:

ciao

my question is this: there is an application or a command of autocad

in autocad there is no "native" command that does this, maybe there can be lisp that execute the decomposition. Tell you which, I don't know, sincerely

or software able to divide into simple geometric shapes a very complex irregular figure

I would like to tell you autocad architecture, in which there is a tool (vans) that identifies an area (it is a tool applicable both to a contour of walls of autocad architecture and to a 2d design of simple lines of autocad) and the break in triangles or trapezes, depends on how you impose the break. each single sub-area has a name (a1, a2, a3 etc.) and the value of each single side of the triangle /trapezio is indicated. If you want you can print the drawing with the breakdown of the areas or export to excel, with the indication of the geometri data and the surface of each individual area.
