[Plugin] SketchyFFD (Classic)

GreenToaster

when selecting a part of geometry and make it a FF group, the edges don't allign with the rest of the mesh anymore after using FF.
I find this also - which is why I requested the "locked edge/edges" function earlier.

So, I still use the script anyway by simply grouping adjoining geometry that I don't want changed, then hand stitching it after using FFD. This seems to do the trick and works out very nicely.

An example:

CPhillips

Locked edges is on my list for next version.

I am not sure about the the other problem. The kink in the chair looks strange but not unexpected given the FFD groups you used. The FFD only moves entities inside the group.

How would you have liked it to work?

GreenToaster

I think the real problem is not the script, it's the guy that sat on the chair - he needs to loose a few . . .

CPhillips

Here is a quick attempt at locked edges. Its clumsy but seems to work.

How:
-Create a FFD as usual.
-Open the FFD group and select the edges you want to lock. If you select a face it will lock all edges.
-Right click FFD->Lock edges. FFD->Unlock edges speaks for itself.

Now locked edges shouldn't move when you FFD.

Get the latest version from the PluginStore...

Just like it works now
The ability to lock edges combined with a good triangulation before applying FF will solve it.

I will remake that chair once S+D is out, so we can have a clean triangulated mesh before applying FF.

Great work on that 'lock edges' option. Very useful upgrade chris .

i downloaded and installed FFD but when i go to use it it does not ask if i want 2d or 3d if i continue it generated a flat matrix which i cannot do anything with what am i doing wrong?

remus

Did you group your geometry, right click and navigate thorugh the ffd menu to the bit where it has the option to change mesh size?

GreenToaster

For others who may be new to this

1 - put the script in the following directory/folder (or find the equivalent):
C:\Program Files\Google\Google SketchUp 6\Plugins

2 - create some geometry

3 - create a group from the geometry

4 - select the group, right click, FFD, select a suitable option

I've also found to it necessary to create a new FFD "box of control points":
A - delete the existing "box of control points"
B - explode the group
C - create the group again - this is ultra-quick & easy b/c the entities in the group will remain selected when you explode the group - leave them selected so creating the group again is a simple & quick shortcut
D - do step 4 (above)

Hope this helps - love that script.

Thanx Rremus it is working now

dolphus

thanx gren Toaster i will start workijng with it and let you know how i progress

Thanks for the update with locking edges, Chris! A thousand blessings upon you for your work and generosity to this community!

remus

Hey chris, would it be possible to incorporate a subdivision element in to FFD? i reckon itd be really useful to be able to subdivide geometry before using FD, as you often dont get good results otherwise.

No pressure though, im sure i cna manage using whaats subd for the moment

remus

Wow, this is liek on demand ruby! cheers chris, im sure this will be even more useful than it was before!

Thank you Chris!!! It´s fantastic!!!

A bug... the 2x2 FFD or 3x3FFD is not working:
Error: #<ArgumentError: wrong number of arguments(2 for 3)>

Alright. Now when you do a NxN there is an option to subdivide.

See first post for download link.

Chris,
You're Da Man!
Kudos!

CPhillips

Updated with another bug fix.

Daniel S

The new added option to subdivide the mesh when doing a NxN deformation it´s amazing!
Only this feature can be a standalone plugin by itself

Thank you,
Daniel S
