Hi Pilou,

> is that result wanted?

Yup! And it's possible to get that result by several different methods currently, this is just a way to make it faster if you need to do it many times.

Moreso probably a lack of understanding of the bisector result. :o

ok So I will can add it to my collection ;)

Hi Michael,

What?! I was hoping for the repeat checkbox :( isn't it possible for the command to end and the curves deselected after the bisector curve is created, so another set of curves can be selected ?

Hi Danny, it's not really easy for commands that involve object selection to work with the repeat checkbox, because things are more primarily intended to work by selecting the objects that you want to work on before you run the command.

It's just so ingrained in things like basic file operations in Windows to do "Noun, verb" operations where you pick the thing you are operating on first before triggering the action that works on it...

In MoI I've also tried to accomodate people who are used to picking input objects after a command has been run as well (which is how several older CAD programs are structured), but that post-pick support is kind of a supplementary thing and not really the main focus.

When you work with pre-selection, sometimes you want to do things like do several operations in a row on the same selection, and if every operation removed the selection from the objects that would not be possible...

So when objects are pre-selected doing an immediate repeat does not work very well because it ends up too literally an exact repeat with the same input objects.

But that's one reason why you can right-click to repeat the last command as a separate thing from the repeat checkbox. The way things are set up now, the repeat checkbox is only for drawing commands where you pick points to define objects, and not for commands that involve selection of input objects.


Of course, it could be possible to make a customized version of this particular command that removes selection at the end, it would just behave pretty differently than how other commands are normally structured.

I've attached a version that does this, I think it's more like what you want and it allows for the repeat checkbox to work, but instead this version does not allow the lines to be pre-picked at all, it clears out the selection at the start of the command and clears it at the end of the command, so it behaves differently than the regular way that other MoI commands work.


Maybe I should have something like a "post pick" type global option that you could enable which would do stuff like clear selection like that when running all commands.

or by commands? so a board with some cases to enable/disable?

Hi Pilou,

> or by commands? so a board with some cases to enable/disable?

I kind of hope to avoid such messy UIs like huge control panels that have lists of options for every single command...

But that could be a possibility if it comes up often. Maybe instead of a huge list of commands it would be something more like a place where you could list commands that you wanted to behave differently as an exception to the normal behavior.

Hi Michael, thanks again and thanks for the explanation.

I don't know, it might be the older CAD thing that I'm accustomed to maybe, it's like that backward hide thing I asked for a little while back, most of the commands are fine it's just some commands feel right when I run the command first then pick the objects.

In NX there's a funny behaviour that's not really documented, I don't think, where each command window has the buttons 'OK', 'Apply' and 'Cancel' after picking whatever you want to do, pressing 'ok' will execute the command and exit the window, picking 'apply' will execute the command and not exit out so you can repeat the command on something else, there is no last command trigger in NX.

The middle mouse button in NX is the OK/Apply button, now the funny thing is if you hit OK in the command window, next time you use that command the middle mouse button is the 'OK' button and the command will exit after the operation, but if you press the 'Apply' button the middle mouse button is now 'apply' for that command and the window stays for another selection, figure the logic in that.

Cheers

Hi ....

What is the practical usage of Bisector curve ?

Hi Anis,

> What is the practical usage of Bisector curve ?

I use a bisector curve for construction purposes, it's mainly used to make it easier and quicker to get the centreline between two lines which can be at different angles and lengths to each other.

Does the plug works with 2 curves? (not lines )

Hi Danny,

Can you give me screenshot sample usage in your project ?

Thank You :)

"""""""Does the plug works with 2 curves? (not lines )""""""""""""""

No Frenchy. At the moment, if you run it on 2 waving curves, it will just create a staight line, who's start and end points are at the middle point between the 2 curves start and end points.

Hi Michael,
I dont want to beat ahorse, but had a question here. Perhaps I am misunderstanding something with the bisector. The script is creating a mid to mid point od the 2 lines at whatever length they are. The bisector "should be the ANGLE"??? With my initial method of using a tangent arc and a line with perp snap, bisects the angle. With the script, it is more of a mid 2 mid line generation.

In this file, the red line is MoI's mid to mid, and the other is the angle bisection...

Have I missed something about what was requested or the desired result. Thanks.

Hi Burr,

> Perhaps I am misunderstanding something with the bisector.

Yeah probably "bisector" is not the actual right term to use for this.

From what I could tell from what Danny posted at the start of this thread, it sounded like he was currently drawing in construction lines between the endpoints of the lines and then using midpoint snap on those construction lines to get the line that he wanted.

So that's what I automated in this plug-in.

I guess you might call it more like a "line blend" or "line morph" or something like that.

You are correct that doing an extension of the lines until they intersect and then forming a line of half the angle between that intersection (which would more properly be called a bisector I guess) is a different result than what this plug-in is doing.

- Michael

Hi Burr,

> Have I missed something about what was requested or the desired result.

No you haven't, you are correct, thanks for picking this up, a bisector line should be a line that bisects the angle between two lines, I took it for granted that Michael understood what I meant, I should of explained after the bisector line is created the angles between the lines should be equal.

Sorry Michael, with Burr's persistence on this he's pickup that the script doesn't produce a true bisecting line, I haven't used it for anything yet just initial tests to see if the script works, no doubt I would of picked it up once using it.

Is it still possible to get something to produce a line that bisects the angle between two lines.

Cheers and thanks again Burr.

So Plug must be modified or not ? :)

tangent arc's perp.

Hi Danny, sorry - in your first post when you mentioned using construction lines I assumed you were talking about connecting the endpoints with construction lines and then drawing in a new line between the midpoints.

What is the actual process that you were using with construction lines previously?

- Michael

Also another that got me confused I guess is the discussion about what to do with bendy curves.

If you want a line that is half the angle between the extended lines, I don't think there is actually anything with bendy curves that corresponds with that, is there?

So when you said that would be good to have for bendy curves as well in v3, that kind of confirmed to me that you must be talking about a kind of Illustrator-style "blend" or morph type operation between the curves...

What is it that you would expect to get from the "half angle" bisector method between 2 bendy curves then?
