[Plugin] Extrude Edges by Rails to Lattice

[Didier Bur]

Hi TIG,
Here is the french lingvo file.
You're making great progress in french, just several typos were remaining
Best regards,

extrudeEdgesByRailsToLatticeFR.zip

[TIG]

Thanks Didier, Pilou also just did one - I'll make a compilation of both...

[TIG]

New zipped set is now available [ http://forums.sketchucation.com/viewtopic.php?p=242239#p242239 ], with minor tweaks to text for lingvo files. New ES=Defisto and FR=DidierBur + Pilou. Flat faces at z=0 are now auto-reversed.

[TIG]

The script in the zipped set has been updated...
'Face.offset' is now reworked to be more robust and 'in class'
[i.e. now offset.rb is not needed].
Panes now get the 'back_material'.

[TIG]

Tip
You are prompted to erase coplanar edges if the faces can survive without triangulation divisions.
To ensure that you get 'flat' quad faces make sure that the profiles and rails are identical [perhaps copy them].
Here is one with the coplanar triangulation left in... This one had them erased before the lattice was made...

[pilou]

That rules now

Here's another form...

And another

this is seriously amazing! been playing with it for hours now! just a question TIG: is there a way to group separately the "glass panes" from the frame? so the frame is one group and the panes are another......

Wow, you did it again!

Give the frames and panes different colors - say 'red' and 'glass'.
Edit the group and select a pane.
Right-click Context-menu > Select > All with same Material...
All the panes are selected, Right-click Context-menu > Group.
Repeat for the frames.
You now have the original lattice group that contains two sub-groups - one for the panes the other for the frames.
Re-color them as desired.
One of the reasons I gave a limited 'rainbow' of colors+glass was to avoid long material lists in the dialog which always causes grief when the color you want is off the screen... and as explained above you can always select everything by a material and apply any color/material onto them that you like later on...

I don't see how I could do the same with else tools

Maybe 2 faces + path + FFD(or fredoscale)

Thank you so much Dear Tig for this new amazing tool.

Pretty good tip!

I wanted to tell this one, but I'm outstripped by TIG

another interesting result is to adjust the depth to 0 in order to get a flat frame
(and use soften & smooth for a simple aspect)

The tool 'EEbyRailsToLattice' was written to do a 3D lattice or the profiles/rails rib-lines as simple separated curves - so you can use them for other things - like 'EEbyFace' using different profiles for different parts...

Extrude Edges by Rails to Lattice + ExtrudeEdgesBy2Faces

Extrude Edges by Rails to Lattice + Didier Bur "lines to tubes" (with and without EEbRtL)



etc.. etc..

Vast possibilities

%(#0000BF)[Dear TIG, may I comment ?
-Extrude Edges by Rails to Lattice uses only ExtrudeEdgesByEdges. I would be really cool if we would be able to pick curves the same starting from ExtrudeEdgesByLoft and also from ExtrudeEdgesBy2Faces or from ExtrudeEdgesByLathe !
-Do you think it would be possible to select also the diagonal curves family?]
with my friendly respect, simon.

[TIG]

Here's an update http://forums.sketchucation.com/viewtopic.php?p=242239#p242239
It now has 'Diagonals' as an option.
Reversing the order of picking the Rails swaps the direction of the diagonals.
The lingvo files have been updated to match.

[olishea]

cheers for grouping explanation.I think i clicked select all connected by color or something.....oopsy

fantastic work TIG, hats off!

[pilou]

As you refine more and more does it possible to generate a "2 colors Checkboard" from the lattice?

I have missed one case

Pilou !
Maintenant vous 'prenez la pisse' !

However, it would be relatively easy - the panes are stored as an array in the logical order they are made.
We know the number of them down the rail and across the profile.
If the number of profiles is odd then every other one is colored, if it's even then every other one is colored, BUT swapping the rule over at every 'rail' step change...
If you separate out the panes by selecting by material and grouping they will remain ordered.
Then find the group's faces...

group=Sketchup.active_model.selection[0]
panes=[]
group.entities.each{|e|panes<< e if e.class==Sketchup;;Face}
0.upto(panes.length-1) do |i|panes[i].material="black" if i/2==1/2.0; end

Swap "black" for your desired color...
This works for odd-numbers of panes across the profile - I'll leave you to do the line of code to do it for even-numbers...
