[Plugin] SketchyFFD (Updated 20130203)

@Puco

The later errors seem to relate to the SketchUcation toolset...
Have you installed the latest version of it - it was published a few days ago, to be fully compatible with v2019...
Perhaps the SketchyFFD load error affected the load of the toolset too.
After you fix that FFD issue [as explain a few days ago], then do you still see the SketchUcation related error messages ?
If so it is rare and unexpected...

But I have an idea...

Perhaps your v2019 SketchUp was not installed properly ?
An incorrect installation can cause all sorts of unpredictable issues, with permissions etc.
It'll work for many things but unexpected fall over on others...
You can try to 'Repair' the installation - it will do no harm in any case...
Here are the steps...
Whilst you are logged into Windows with your normal user-account, ensure that SketchUp is closed.
Find the v2019 SketchUp installer exe file - probably in your Downloads folder [the default location].
Select its icon and right-click > context-menu > "Run as administrator"...
When prompted choose "Repair"...
Restart SketchUp to see if this have improved...
Report back...

Installing any complex app in newer versions of Windows in any other way can lead to all kinds of flakiness...
Double-clicking to "Run" the exe installer is NOT the same as using "Run as administrator", even if you have admin-powers as a normal user the result will not be exactly the same !

This IS a very plugin !
The code in ../Plugins/SketchyFFD.rb is throwing an error in line#32 where there's a misplaced 'return'.
This doesn't affect earlier Ruby versions, but fails in the newest version shipped with v2019.

To fix it do the following...

Find the RB file in your Plugins folder.
Edit it with a plain-text editor - like Notepad++ [or TextWrangler on MAC]
Find line#32 and edit it.
Change return nil to #return nil [with an additional leading #]
Save it and restart SketchUp, it should now load OK... provided that your Extension Manager Loading Policy is set to Unrestricted...

Note that its submenu only appears in the context-menu, and it is only 'full' if a suitable Group is selected...

Firstly, have you fixed the code as explained in the previous post ?
PS: Please get the latest v6 which is fixed for you - see next post...

You are getting an odd message - please post it all.
However, I suspect it results from the selected group containing no editable vertices - e.g. if the selected group contains some other group[s] or component-instances, but no 'raw geometry', then there will be no vertices in it for FFD to process. Look in the Outliner and explode the nesting, OR edit and perform the FFD operations on a group that does contain raw-geometry which will in turn supply the needed vertices...

Put simply, you select a group and use the context-menu to apply some guide-points in a 'cage'.
These are grouped separately, so to select them it's easiest to use the Outliner.
Edit their container and move the points etc to deform the connected group's geometry...

Because we've had a lot of confusion with this old Plugin - especially with v2019 - I've updated its RBZ in the PluginStore.
Now v6 should be compatible and it is also 'signed'...

Support for rotated groups would be a big deal in this plugin.

Any further development is unlikely - this old plugin has not been updated much in ~6 years.
To work on a rotated group...
Rotate it.
Select it.
Explode it.
Immediately make a new group of its still highlighted contents using the context-menu.
Rest its name, material, layer to match the original one...

It is probably easier to do it, than it is to write it, and it is certainly easier than [re]coding it...

The 'dots' are guide-points, these are only visible if you have set View > Guides > ON [ticked]
Is that your issue ?

A cool trick for use FFD is to use the Onliner + Xray for an easy selection of what must be selected! :ugeek:

Your explanation is unclear.
You say the dots don't appear, then you say you move them ??
Do you have View > Guides set Visible ?
Do you use the Outliner to edit the points' container and move them ?
Please supply a SKP showing the issue, with a step-by-step guide to what you are doing...

SketchyFFD example.png


Hi,
Thank you for the nice plugin.
However, I ran into some problems with FFD when I wanted to make shapes with the NxN FFD option. For example, I go for the setting NxN FFD 3-3-3-true to subdivide a cube, then I move some selected control points but either nothing happens, or the whole cube is broken and some faces are missing.
Would you be so kind and help me with that?
Thank you! Best, Meda

Please post a simple SKP model which displays this problem.
It is a very old plugin, so it can be flaky... so no promises about a fix...

This tool is run from the right-click context-menu items, which are available when there's a suitable selected group.
Also use the Outliner to access then edit the associated cpoints group...

I installed your plugin (SketchyFFD v6) on SketchUp 2018, but after installation the icon and generally the tool did not appear.
maybe I should install the old version of the plugin v2018? Could you drop the file?

sorry for my English. :)

Please read the main post which explains the tool's usage.

As I posted recently
This tool is run from the right-click context-menu items, which are available when there's a suitable selected group.
Also use the Outliner to access then edit the associated guide points group...

Do you suppose or you know for sure? Could you post some illustrating gif or give a link for existing video?
I set configuration of guide points by entering numbers in NxN FFD window.
No matter what numbers I put in 'make patch' dialog window the only thing this option does is miserable 3X3 patch at 0,0,0.
And I still don't understand the goal of this thing.

Goal (of Make Patch) is to create a terrain at any nodes dimension that you can modify after with FFD itself! :ugeek:
Here a flat "patch" 5*5 (nodes Width, Deepth) with Cells 10*10 = a flat tilling of 16 pieces!
then FFD modifyed by 2 points of a 4*4 "FFD": very cool and easy one! :enlight:

Else some other cool uses ;)

So the 'width' and 'depth' are the number of 'grouts'
And tile dimention is 25.4cm (in metric file)
Such a bizarre "utility" :shock:

It's very flexible if you take several of them in different orientations! ;)

You have something else if this above is not sufficient! ;)

(that will be also modifyed by FFD or with it's own internal move points system... ! ;)
