[Plugin] Recurve
-
@Diggsey, thanks for the plugin.
@Wyatt, there is a plugin by Fredo6 (called RevertCurve) that will reverse a curve's direction: http://forums.sketchucation.com/viewtopic.php?t=25710

Awesome. I didn't know about that plugin. Probably would have saved me hours last week.

Welcome to the forum and thanks for sharing. Very nice introduction.
Iæd just like to point out a post I made about context menu handlers: http://forums.sketchucation.com/viewtopic.php?f=180&t=31788
Basically, iterating over every entity in a selection can add a significant lag when you have a larger selection set and it should be avoided so that SketchUp's context menu doesn't end up lagging several seconds. -
Thanks for the heads up about context menu handlers. I'll change it in the next update. I've added the ability to reverse curves but I'm still trying to fix some bugs. Somehow the curves are being split up which is weird...
-
does this perform the same function as weld?
-
-
Just updated the plugin to v1.1. See the first post for details and download.
-
I'm getting a bugsplat when trying to reverse a curve with more segments - like arc with 120 segments.
-
I've fixed the bug for large numbers of edges.
The algorithm used to use recursion to find a route through the edges and that cause a stack overflow. Now all the algorithms work using simple loops.
See the first post for v1.2

Working fine now! Thanks!

I noticed reversing an arc makes it curve - it is not arc anymore. Is that the way it works?
-
Yes, currently it only makes curves not arcs. The reverse curve command basically explodes the curve and then calls recurve on it in the opposite direction, so the arc information is lost in the process. I could try changing recurve so that it detects if the sequence of edges makes a perfect arc.
The problem is, there are some arcs that are almost impossible to recreate. If you create an arc and then draw a line through it, you get two arcs, neither of which can be drawn with the arc tool. Even changing the number of segments in them will change their shape irreversibly.
Alternatively, if there are SketchUp features which you need to use and only work on arcs, I could make them work with all curves.
-
I see - thanks for the explanation. Just noticed this and wanted to be sure it is not a bug.

why not just detect if you are exploding an arc?
-
That doesn't help solve the problem I mentioned though. The only way I know of to create an arc in sketchup is with Entities.add_arc, which is functionally equivalent to the arc tool. Arcs created by dividing another arc in two cannot be made this way. I would have to know the exact sequence of events which happened to create the arc in the first place to recreate it in the opposite direction.

What is the difference? I thought an arc was a curve.....
-
An 'Arc' IS a 'Curve'... BUT a 'Curve' is NOT necessarily an 'Arc'...
Also remember that 'Circles' [a special 'Arc' that's 360 degrees] and 'Polygons' are also types of 'Curve' - as is any bound-set-of-edges that has been made as a 'Curve' [e.g. a Bezier Curve or a 'Welded' Curve made from edges]........... -
probably my oldest plugin request has finally happened
weld with no dialog boxes.a few suggestions (if you're open to it, of course)
say i have two lines with an arc fillet connecting them and i'd like to make them all a single polyline (ie- something i do a lot with weld.rb), the recurve function won't work (or it doesn't appear in the context menu).. in order to recurve that scenario, i have to first explode the arc (or any polyline segments) prior to being able to recurve.
it'd be nice if i could weld a combination of edges/lines with curves (or arcs,polylines,etc.. what ever you want to call them
) using recurve.there's also a bit of weirdness in there as far as 'select curve' goes.. using the same scenario as above, if i right click on the arc fillet then the 'select curve' option doesn't show up.. but, if i right-click on either of the lines then 'select curve' does show up and if i choose it, all parts including the arc will be selected.
and taking that a step further, it'd be nice to have an option for 'select curve then recurve' (or whatever) so i could select a bunch of broken segments and weld them together in one operation..
ultimately, this will definitely replace weld for me as my W shortcut and the last request would be assigned to ⇧W .
thanks a bunch!

Super helpful, thanks for sharing
