Extended Entity Data for Polyline?

[fabiocosta81]

I would like to put in a polyline data for each segment each section would have a height information to calculate how do I do that?

Don't use xdata much myself. Did you look at what @BIGAL said?

It is not possible to attach separate xdata to each segment of a polyline.
This would be possible by decomposing the polyline, and so you could attach the distinct xdata to the resulting lines but you would lose the properties of the polyline; especially the surface.

The easiest solution would be to create duplicates: one layer with the original polyline and another with the constituent lines so you can attach xdata to it.
Is this possible?

[BIGAL]

You could attach H1, h2, h3 etc problem is must be consistent so how many H's when set up xdata.

Adding polyline data for each segment if you didn't limit it to using Extended Entity Data. As the segments of a polyline are not separate Entities adding Extended Data to each of them is impossible. Lots of lisp out there for labeling polyline segments if that's actually what you're looking for.

 

Of course unless you're talking about a 3Dpolyline the Height is the same for every segment like in the example you've shown so why would you need to label it more than once?

In a 3Dpolyline the Height could differ on each vertex so labeling Height of a segment with different Height on each end wouldn't make any sense. 

 

If you could better describe what you're looking for the responses you've seen already should show you there's plenty of folk here willing to help you.
