Looking for a lsp that adds the total length of lines/plines/arcs, but separately for straight lines (and polyline segment) and for each group of arcs (and arc polyline segment) with the same radius

[jakob.holmquistGRCUL]

Hi!

I'm in need of a lisp routine that will help me calculate the amount of curbstones a drawing contains. In my country we are to specify the total lenght of straight curbstones, and total length of circular curbstones for each unique radius so that the contractor can order the correct amount of materials when building. So the lisp needs to go through all objects in one specific layer called M-DEC---E1N and add the total length of each line and straight part of polylines, and do the same for every unique radius for all arcs and arc segments of polylines. Preferably it would be presented in a table and would look something like this:

Segment           Radius          Total length

Straight line          -                          150

Arc                          1.5                        25

Arc                          2                           32

Arc                          6                           14.2

and so on.

I attached a dwg with an example of some polylines, arcs and lines and a table, where the table is supposed to be the output of the lisp.

I have found this lisp that calculates the combined length of all plines/arcs/lines for each layer that I believe was created by a user called phanaem. Maybe it can be modified to work as I stated above, but as I am a beginner at programming in lisp this is out of my reach. Any help is really appreciated!

... 2D polylines are not accepted as selection, and their lengths are therefore not calculated. I tried adding "POLYLINE" in the part of the code that specifies what sort of objects are accepted as selection, ... but their lengths were not calculated, neither the straight or arc segments. ....

For that part, if they're going to be processed in the same way, rather than an (or) function checking for both types separately, you can check for both types at once, like this:

((wcmatch (vlax-get to 'objectname) "AcDbPolyline,AcDb2dPolyline")
