[Plugin] Blend ver 1.12.

kirill2008

Hi, Bob.
Thank's a lot for your feedback, it really helps to improve the script.

Dear Kirill,

that the 'undo' doesn't work with your plugin, i.e., I cannot revert back to the drawing before your plugin is used, and

Well, actually 'undo' works, but yes it sometimes (big steps count value and/or big segments count of initial curves) cannot revert back drawing.

Animation shows '<Ctrl>+z' combination pressed effect.
Now (ver 1.3) all steps of Blend command joined to the single command and can be undone as one single action.

@watkins said:

your plugin creates lines (steps) which are outside the group which contains the surface. One has to hide the group and then delete the lines. Is this how the plugin is meant to work?

Yes, they are supposed to be separated. But now (ver 1.3) I decided to put curves to another separate group.

@jclements said:

If you can get two objects to follow and blend along a third, curve (path) as was suggested above, then we've got a nice, easy-to-use taper tool.

Well, the final destination is an interactive blended object, that consists of 2 initial curves/faces and maybe a path. Interacting with initial curves and/or path has to affect the whole object. Sounds like a kind of challenge for me...

Very interesting tool, kirill:
Seems to have qualities of Skin.rb and Simple Loft.rb but on steroids.
Excellent work!

Ver. 1.4 is able to process more or less complex geometry.

This plugins looks great!
What about blend colors too?
Here an example that creates intermediate faces and colors from two existing ones (2 steps).

Of course this is not sketchup, is only a simulation.

Great script, i've been waiting for something like this for ages. Couple of odd bugs with circles (v1.4)

seems to miss out a segment when doing a blend
if you create the second circle with a move copy, you often get something like this

ken

Note sure if it me or note. But I tried V3 and was pleased with the results, however, V4 does not seem to display the same results. Note, I dont' have V3 any more, as I copied over the script, so this is from memory.

I particular like how if blended a square to a circle, now every time the output has folds or is not a straight blend from the square to the circle.

yeah, I had a gap between the originating curve and the next intervening step toward the destination curve. Easily knitted together with line tool, and so forth, but just mentioning.

This is a nice plugin, mate! I'm going to play!!!!

tomot

Nice plugin! but still needs some tweaking.
I find it first works with a new fresh startup screen. but then the more experimenting I do with Blend the more inconsistant the results become, finally the Bend of the left Y's in the picture did not take place at all.

Error; #<NoMethodError; undefined method `vertices' for nil;NilClass>
C;/Program Files (x86)/Google/Google SketchUp 7/Plugins/sublend.rb;45;in `blend'
C;/Program Files (x86)/Google/Google SketchUp 7/Plugins/sublend.rb;174
C;/Program Files (x86)/Google/Google SketchUp 7/Plugins/sublend.rb;153;in `call'

please don't give up!

cosycat, please try ver. 1.5. I tried to solve the problem of missing mesh pieces.

tomot, I'll try to find out, what's the problem with rotated Y's...

And speaking about the 3'd curve (the path): looks like, it demands a kind of major refactoring It is more complex task than I thought and it will take a little time...

tomot

I don't want you to misunderstand. This is not only related to the "y" shape. Other shapes have produced the same inconsistent results in SU 7.
another example:
make 2 identical closed shapes, scale one larger, apply bend, same code error occurs

cheers.

Looks like it is SU7 issue... SU6 processes correctly:

When processing faces it is necessary to select them by single click (not a fence).

majid

woooow...it would be a dreamy plugin if no bugs!!..I gave it a try , but it seems that previous versions were better on freehand lines, while the last version doesn't works fine... also on closed line doesn;t works at all (su 6)..seeing forward to see the improvements mate btw thanks thanx thanx!

Dave R

This is a useful plugin. Well, for me it was until I installed the latest version (1.5). Now I get what you see in the attached screen shot. Unfortunately I installed over the previous version. Keep working at it. I'm sure you'll get it all working.

Thank you.

Daniel S

Thank you for adding color blending

I have problems with this new version too (I use SU7).

Sometimes work with results like the ones Dave R post above.
In other cases the plugin dosen´t do anything and prints this in the ruby console:

Error: #<NoMethodError: undefined method back_material' for #<Sketchup::Edge:0x67b7f70>> C:/Archivos de programa/Google/Google SketchUp 7/Plugins/sublend.rb:68:in blend'

Dear Kirill,

It might be a good idea to post versions 1.0 to 1.5 as the later versions seem to be problematic. Version 1.0 seemed to work quite nicely. I too have over-written previous versions and so cannot go back a step or two.

Kind regards,
Bob

watkins

Dear Kirill,

Version 5 doesn't seem to work in SU Pro 7, even for simple shapes, but don't give up.

Thanks for posting versions 1.2 and 1.4. I will test them out with areas. Previously, I only tested this plugin with arcs, and that still works in V1.5.

There are three previous versions:
v 1.2
v 1.3
v 1.4
Rename files in sublend.rb

sublend__1.2.rb

sublend_1.4.rb

sublend_1.3.rb

Guys, I don't know yet how to prevent skin (mesh) turning inside out The point is that script processes vertices with corresponding indices: so maybe flipping normal or 180 degrees rotation (or 90) of one of 2 faces may help.
Missing triangles (they vanished after color blending feature addition) have come back now (ver. 1.6)
Error messages kind of "undefined method `back_material' for... " debugged (I guess ).
