Topic: Pline: Is ortho? (segments)

[Lee Mac]

Excuse my ignorance, and without me try to understand something above, can  you indicate what functions are accounting for bulge?

My posted functions are accounting for bulge (i.e. returning nil if the polyline contains arc segments), yours & VovKa's are not.

About adiacent vertex (see image and dwg posted) what do you think? we consider orthogonal?

I would say so, yes.

After a quick test ortho-p5 seems the best. Thanks.

You're welcome!

Note that, as Lee noted, these make assumptions about the parameterization of a polyline that may not always be true. See e.g. QuirkyPolyline: exposing foolish programmers.

I re-read all the messages but I do not see where Lee said that.
Regarding:

I think I understand that there may be no exact values but only in complex curves? I misunderstood?

Another option, with reliance on integer parameters at vertices...
