polyline - auto lengths - help please

[Anonymous]

HI.
I use few poly-lines in my .dwg, is there any option to make table with measurements of poly-lines i.e.. between
A1 - A2 - auto fill length
A2 - A3 - auto fill length
etc.
So when I have to change polyline it will change it's length automatically in table.
Will appreciate...

You can have a table with the length of an individual polyline that automatically updates. I don't know of a way to have distances between objects automatically update. Could you provide a more specific example of what you want?

If the request is to label or summrize individual polyline segment lengths, there are a bunch of routines you can use.

If the request is to sort out polylines in different length, the user need define the rules of the length ranges, eg. Group 1 = 0mm ~ 1000mm; Group 2 = 1000mm ~ 1500mm, etc.

That's what I need - a table with polyline's lengths - single polylines (see attached drawing). A0 to A2 it's a single polyline so I just need length of it in table.

How can I do it?

You can create a FIELD in a table and link it to the length property of an object, in your case, the object is a polyline. You have to break a polyline contains more than one segments into separate segments because field only counts the length of entire object.
