Normalize spline retain corners by angle new method to solve the overlapping vertices issue

[JadBox]

- normalize spline modifier can sometimes break the procedural workflow by creating overlapped vertices that need to be fixed manually.

- so it will be useful to give the option to retain corners by min and max angle, for example if you draw a rectangle then you can normalize and set the min angle to 90 degree so it will be normalized but retain the 4 original corners, now the new vertices will have the specified spacing (for example 20 cm) ignoring the original 4 corners of the rectangle (the spacing is passing through the original vertices).  

- right now we can use the -Retain Knots Within- option but in my experience on more complex splines most of the time it leaves overlapped vertices.

- one more option will be nice to have is the ability to normalize by segment, this will work by normalizing each segment alone by starting the new vertices spacing for each segment independently (the spacing is independent for each segment) and you can give the option for min and max angles for this option also, to determine which segments are considered to be normalized together or independently.

Can you post some pictures when this is failing!

@Kranos_Orphydian here is a simple one you can easily recreate, you can notice how at the end of the spline there is two vertices. I know I can fix it by fusing vertices together but that will break the procedural workflow, or I can keep adjusting values to make it work but it's not convenient to do so, a lot of time I need to create equal segments on the spline and most of the time I can't achieve that without breaking the procedural flow, or I have to compensate the accuracy of the segments length.  you can see at the end of the spline its creating an overlapped verticesadjusting the values can solve it but now some corner has become bevelled which i don't need it to be like that

Indeed, there are very good points here. I forgot I already included something similar in my bigger idea on spline procedural handling improvements? [Splines] Improved procedural handling through both updated and new modifiers - Autodesk Community

Can I include this idea directly there?

sure i will add the pictures you provided and i will try to explain it in more details if i could manage, but still add it to your thread if it will help fix this issue. for what I understand that the developers would prefer to have specific idea at a time so they can solve an issue, I believe its more convenient to tackle one thing at a time.
