I have a very novice question. I'm trying to download the SketchyFFD plug in but I can't see where the link is to download it. please tell me how to find it on this website. Thanks

it is at the bottom of the first post, just click on it and save it to your plugins folder.

very cool stuff..thanks alot..makes very easier working with organic shapes
FFD..rocks...

just have the best here . thank you .

Erm, i'm new here. i have sketchup 8 and i've put this ruby into the plugins folder with all the other rubys, but i can't find out how to use this in sketchup?

Hi, itscabbage:
I would highly recommend reading through the entire series of pages in this thread. Among the pages are animations, visuals etc. that can provide information on how to use the tool. If you are unable to activate it, perhaps you should check to see if it is in the proper folder. This is dependent on whether you are using Windows or Mac.
FFD does take a little practice.
And, if you haven't already done so, update your profile. This will enable helpers to determine specific solutions, especially with regard to operating systems.

For some reason, only the first version works for me.

I set NxN
width=11
depth=11
height=1
subdivise=false

First version everything is OK, scale move rotate...

Second version, nothing moves (see ruby report)

Tig's version, trying to move the original group just disappear? no console report.

Any idea?

I made the adjusted version because the older versions were all causing issues, clashes with other scripts etc, the observer was very flaky...
My version works fine for me when tested using your settings, although I don't fully understand the 'moving the group...disappear' issue what disappears ? If you move the group away from the guides it will deform differently...
You can only have one set of FFD guide-points at a time, so is this your issue ?
The 'second' version had the most fails so I'd expect the litany of error messages...

gilles

I set NxN parameters and clicking ok the group disappears, it is still in the outliner but nowhere in the model.

gilles

I also try with only SketchyFFD.rb in plugins folder, same result.

SU 8.0.14345

TIG

It works fine for me with z=1 set, provided that the geometry has some 3d-ness.
If I draw a grid 10x10 as a flat 2d group it does then fail !?
Not having written the original code [I just fixed some known issues] I am unclear why...

Adding a short vertical line to the grouped mesh fixes it... I'll check though the code and see if I can trap for this...

gilles

If I add a vertical line in the group it works.
Good to know.

TIG

Here's my update http://sketchucation.com/forums/viewtopic.php?p=36127#p36127
The recently reported NxN issues with NaN [0.0/0.0] & Infinity [1.0/0.0] fixed, these occurred when the selected group was 2d & NxN height=1...
Also the NxN dialog now remembers the last used values that session for the NxN lattice [width, depth, height, subdivide]...

gilles

Works great, thanks a lot TIG, have a sunny day.

Thanks! This is awesome!

But did the old version ?
There is little difference with this update !
How are you trying to deform a sphere ??

Sorry, operational errors, thank TIG

eshertoding

i can't find the "update ffd" after i move the point and close grup
can't anyone explain me?

thank you!
