@dtrarch - Lofting 3 equal arcs in SUv6 gives bug splats? But 2 equal arcs do not, correct? Could you post a model that splats?

I'll look into it and I have a pretty good idea where in the code to start looking. I can't think of anything I've done that should splat though. Oh well, I'll try to check it out.

Bummer Sepo, your getting splats on any loft in v7?

Could you attach a file with shapes that splat? I'm not sure if this is a script conflict splat or if you guys are using it in ways that never crossed my mind (like with shape bender, I'm amazed at what people make that script do!).

So perhaps attach some example models and I'll take a look. Thanks!

Chris

EDIT: Sorry, in that previous post I was answering dtrarch - I'll edit it to make it more clear.

Dear Chris,

I cannot seem to get your plugin to work. The loft icon appears in my toolbar, and seems to work: it changes when selected and allows the selection of the two curves (simple arcs with the same number of segments), but then nothing. I even tried exploding the arcs, but still nothing.

As usual, I put the simple_loft folder and loader in my plugin folder. Is it possible that one of my other plugins is causing a problem? I have tried your plugin on two different computers (home laptop and office desktop), but with the same result. Both have the same plugins. Curious.

Kind regards,
Bob

Dear Chris,

I do apolgise. I had a senior moment, or to be more precise, I failed to read your instructions to the end. Hit ENTER was the missing step. Seems to work just fine now.

Kind regards,
Bob

I checked V6 with only loft installed.
It is bumping into another script or ?
The same script set is on V7 and loft is OK there.??
BTW the number of arcs 2-whatever still bombed.

Sepo, your issue to me looks very much like an observers problem - specifically a collision with another script that is watching the selection set being added to. I'm sorry for the hassle, but you might need to remove plugins a few at a time until you find the culprit.

@Bob, glad you found the problem. That was going to be my suggesion, but I'm glad you got it working! The bowl looks great. I'm guessing you made it using half circles and then combined them together? Very nice!

@Dave, weird that it is splatting on version 6. You tried it with nothing else installed? Are you on Vista? Is there a chance you have any hidden plugins in the compatibility folders? That has ruined my scripts for more than one person already....grrr. Could you open the Ruby console (Window>Ruby Console) and see if you are getting any notices in there when running the script?

@Jeff, thanks! Glad to hear its working good for someone.

I really don't know whats causing some of these splats. We'll keep trying to troubleshoot it.

Thanks for the feedback,

Chris

OK good news is it works on my laptop on both SU7 and SU6.
On my other XP I found culprit. It is tt_double_cut.rb.... As soon as I removed it(as this was only one which was not on all comps) loft started to work.
I know Tom's script is only alpha but it seems to clash with yours.

Heehe, Thom is really digging deep into observers in that script. I'll PM him and let him know that he's got a leak. Thanks for taking the time to find it Sepo!

Not yet. I started with open splines only. I have to rethink some pieces of the script to get closed splines to work.

so far, it seems the best option is to create two halfs of the closed loop you want (be it a circle, elipse or anything else). Than you loft and join them.

If you want to loft a circle to a line, MAYBE its possible to cut the circle in two. Then you loft half the circle to the line, and then you loft the other half of the circle to the same line. Then you join the two sides.

I know Tom's script is only alpha but it seems to clash with yours.

Double-cut should not be used in a production environment. It makes SU unstable, liable to bug-splats and interferes with the observer events. It will need major rebuilding to make it work, so I won't be looking to track down bugs in in the alpha. It is in it's current state FUBAR. I need to get my thinking-cap on first before I start on re-writing it. (I also need a minor break from it as well as my frustration level increases just by looking at it as it is now :( )
Sorry for the inconvenience.

Sorry to hear it Thom, its a plugin with a lot of potential. Hopefully the observers situation will get worked out and stabilized in future releases.

Good luck with it when you feel like getting back to it!

Hi Chris, and all the others (my first post)
I find the first version of your script (0.1a) is realy a good start. The loft tool in moi 3d have the same result with two curves. The bezier connection seems only necessary with tree or more curves. It makes a smooth connection between curves. Anyway. This is the tool missing in sketchup. How brave you are! Thank you for your script, and all of you who keep sketchup fascinating.
Moujiik.

Hey moujiik, that is a great image that clearly shows what I was asking about. Indeed it just makes straight connections from point to point with only 2 splines. Its not until you add a 3rd spline that it starts to use a bezier connection.

In the current version, I faked in a bezier curve even on 2 curves, and I think I'll leave it in place. Partially because I've also now added the ability to control the amount of curve. So if a user selects just 2 splines and wabts the straight straight connections, with multiple segments, it will be possible in the next version I release.

Thanks for the image and the kind words!

Dear Chris,

What I actually did to get the bowl was to:

* start with a circle about the origin, and on the X-Y plane
* explode the circle
* delete one segment
* move and copy the modified circle in the Z direction
* scale the upper circle about its centre
* use simple_loft
* stitch the open part using the line tool

Regards,
Bob

What happens if one tries to use two half circles to create a bowl (see image). The edges are not suitable for joining.
