OH, I found it! Thank you very mush!!

Version v2.1 is now available in the PluginStore http://sketchucation.com/pluginstore?pln=PipeAlongPath It fixes some rare issues when edges in paths have a very slight skew in Z, it still warns if <~0.3 degrees etc which might Bugsplat, but traps for such slight differences which have previously caused a failure, but which would not have caused a Bugsplat...

Please test and feedback...

TIG

Version v2.2 is now available in the PluginStore http://sketchucation.com/pluginstore?pln=PipeAlongPath It addresses a glitch with the misplacement of node-cpoints [if that option was set], if the path was found to be slightly skewed, and the user chose 'No' in the additional dialog to process things anyway...
Now the node-cpoints are correctly placed in every case...

thanks again Tig

great work as always, and most genuinely appreciated

I am very green;experience and envy ! Thanks to Tig and others who have gone before. Trying to create a square tube spiral to specs. Steep learning curve. Thanks

Great plugin, thanks! Is there perhaps a way to extrude a specific profile (instead of just a circle as with the pipe extrusion here) along, say, multiple different curves? I have a louvre profile which I wish to extrude along many different curves. Ideally I'd like to select all of the curves, select the profile, and then hit 'extrude'.

look at
http://sketchucation.com/pluginstore?pln=DM_ProfileBuilderFree_v.1.1.0
That's the older free-version, there's a newer/better version available for a few $...

hey TIG, just want to thank you for your pipe along path plug in! Fantastic !!! On a v tight deadline here and your plugin has saved me untold grief. Cheers, Paul

Thanks to author for great plugin! But I encountered the situation when I tried to make a pipe it caused my SU 2013 hang. I suppose the reason of that some problem with my edges or connections, even though TT's Edge tools inspections were done. Can anyone say what was wrong with edges? Sorry for my English

Pipework.skp

TIG

There are 8 edges connected in that SKP.
Selecting them all and running PipeAlongPath I get no issues.
The pipe forms perfectly and quickly.
I can also draw a circle centered on the vertical line's end and then successfully use FollowMe on the selected path.
Can you do that ?
Do you perhaps have another plugin loading that has an Observer ill-advisedly messing with group creation etc ?
Have you installed something new recently ??
Try disabling most of the plugins, except PipeAlongPath, then retry and see what happens.
It it no longer fails you know that one of the disabled plugins is messing you up...

Thanks you for quick response

Yes, I performed that and everything's well

@tig said:

Never heard about such things. I always try to load not too many plugins

@tig said:

Just updated some of plugins.

That's not the shortest way actually) Anyway thanks a lot. I will try.

TIG

You can probably reduce the list of possible culprits by looking at the recent updates or those with do complicated processes - they are more likely to have observers etc...
Can you post a simple list of your installed plugins ?

You also have some 'old' ones that I think might not belong in there - there might be newer su_ versions available ?
... e.g.

ocean_extension.rb
SimplifyContours.rb

You're right. Many of plugins in my set are a bit old.
OK. I deleted those you've mentioned, relaunch my SU, select the whole chain (of edges), run PipeAlongPath and stil got SU hang. Looks like my Plugins folder needs total revision...

amis

I've tried another way. I redrew the same chain (of edges) near existing one and had no problem with making pipe. But still got the hang with existing chain.
Finally after revision, deleting some of and reinstall/updating all of existing plugins I have no problem. Unfortunally I missed at which step it happened. Thanks TIG

I find this plugin very useful to draw scaffolding poles when designing amateur theatre sets using scaffolding as part of the structure. I've reset (in the code) the default sizes, and options, to suit my use.

I'd also very much like to have the plugin create a component, rather than a group, and to orient the component axis along the direction of the first line segment in the path. Would that be difficult?

I don't think my own SU Ruby skills are quite up to this, though I may well have a go - I might to able to code for component creation, but have no idea how to set the component axes in Ruby.

TIG

You can do it several ways.
Without recasting this as a Sketchup Tool etc I think your best bet is to make the group as it is.
Then later you can turn that into a component instance...
At that stage the origin of the group, and now the component definition ,is at the bounds.min of the container.
To relocate the axes you need to do theses steps...
Get the vector from the point you want the axes to be back to the container's origin.
Then transform all of the definition's entities by that vector.
Then move the instance by the inverse transformation, so it doesn't visibly move BUT its origin is now at the desired point.
I assume you'd probably want that to be the center of the start of the extrusion @new_pts[0] aka pt1 ?
You always want the axes to align in the red along the pipe ?
Insert something like this order around line#490 [untested]...

hi TIG,

I am having repeated crashes while using PipeAlongPath to create a handrail. the model is small and should not be a problem. I wonder if there is a conflict with some other extension. list of extensions attached.

any ideas?

With your SKP I get the Bugsplat! as well.
So something is odd in your path...
I can make it work with an exploded path and 8s extrusion... The issue is caused by the tiny geometry you try to make by having very segmented 'sweeps' between the long rails.
If you make 90 degree junctions it works at 24s OK...If you want radiused 'sweeps' make them at least the diameter of the tube...Here the swept radius is 26mm, the tube is 25mm radius [5cm diam] - so that works...
This is a 'full-sweep' between the two main rails. escada-emergencia_Leste+FullSweep.PNG
Make a swept arc that's tangential from the mid-point of the two rails.
Copy that and rotate it to match the other slope...
Then weld the path and the rails sweep seamlessly around a curve as I suspect you'd prefer...
