You need this file
#SilhouetteToPlane.rb >>> Plugins Folder
You must also have this file
#WorkPlane.rb >>> Plugins Folder
___________________________________________________________________________
Usage:
Make or choose a 'WorkPlane' that is located on the 'plane' onto which
you want to project your 'flattened' Geometry.
Select the 'WorkPlane' and the required Geometry [Edges etc, note that
Faces etc will be ignored], and/or Groups, and/or Component_Instances.
Run this Tool from the menu 'Plugins' > 'Silhouette to Plane'
or type 'silhouettetoplane' in the Ruby Console.
If there is no 'WorkPlane' and/or other objects in the Selection you get an
error message.
Assuming it runs...
All Edges in the Selection that are not 'hidden' or not on 'off layers' are
projected onto that 'plane'.
The new 'flattened' Edges are put into a new Group named 'SIL_123456.789'
[it has a 'date/time' suffix].
Each new Edge takes the original Edge's layer.
The new Edges are inspected and only those that are needed to form a fully
faced 'silhouette' WITHOUT cut-outs are retained.
With this version internal 'hole' cut-outs in silhouettes are NOT formed.
On completion the new Group ['SIL_123456.789'] is left highlighted.

Version:
1.0 20101022 First release.
1.1 20101023 The correct Plane of a 'WorkPlane' is now used even if it has
been Transformed inside its own Group.
Speed and reliability improved. Title fixed.

very good idea TIG! Although, I am getting some errors here - with a single loop of edges it works fine, but for several faces it gets messed up:

btw, would it be possible to have the projection lines run all to the same focal point, similar to Radial Lines plugin? Like this we could also have a flattened picture of a perspective view.

This is the first [buggy] release!
Can you post and example SKP so that I can see the errors...

[shura]

SU 7.1 on Vista, have tons of plugins but only one error so far (wxfsu) ...

[honoluludesktop]

TIG, How many plugin, and point releases are you currently averaging? 1 a week?-)

And, you still find time to help us. Thanks!!!!!

[Pilou]

1 a week?

1 a day is more appropriated

[Didier Bur]

Hi TIG,
I suggest you change line #63 to: @model.start_operation("Silhouette to Plane")
Thanks for all your hard work !

Great Script! Perfect for sorting out faces that have trouble closing. Could you possibly have it so that if no work plane is selected, that it will default to a placing the silhouette on the 0 z plane? Similar to ThomThoms Flatten script in his "Plan Tools", except yours automagically creates the face and groups it.

You could always make a quick WorkPlane on the ground...

[shura]

Just great! You are a hero, hats off to thee!

[TIG]

Here's an example...

This sort of image must be at each first post

[EarthMover]

Here's another example.

Silhouette to plane is also great for flattening a set of looped edges you want to be planar to form a face, but cant seem to find the vert that's out of whack.

[xrok1]

this could be great for making face me components! render the 3d version then apply as texture to the 2d.

[Ben Ritter]

TIG, fabulous! Thank you for the flatten to plane script as well. You are very generous, and gifted.

[Caleidos4D]

TIG!!!

[danbig]

Thanks, TIG. Amazing script.

Does this plugin do the flatten to plane, or is that a separate plugin? I can't seem to find the command for flatten to plane. (Silhouette to Plane is working great)

Just to point out again what Adam already said, Silhouette to Workplane makes closing difficult outlines sooo easy. Brought back the faith in freehand tool to me.

Rocky, that is a pretty smart idea. I am having thoughts about this kind of matte painting tricks all the time.
(like here: viewtopic.php?f=79&t=31069)

thanks again for your generosity TIG!

When I click on the script's download button the #SilhoutteTpoPlane.rb downloads. I put the script in the plugins directory of SU8. When I open SU8 I get the following error:

Error Loading File #SilhouetteToPlane.rb
no such file to load -- #WorkPlane.rb

Should #WorkPlane.rb also have been downloaded?

IF you had read the notes you'd see that you need 'WorkPlane.rb'... because you must first make and then select a 'WorkPlane' with your other parts you want to project - that's how it knows what plane to project its result on to...

[CAntonis]

Working great as always

Thank U TIG

[Bertier]

sweet

[Heven7_floor]

Thanks , it is great script for mechanic model favour, this plug-in shall mostly advance to project 3d model in STD plan,

but I found some error happen, when I test by simple cylinder ,which was rotated a bit from origin , there are 1 error time of total 4 time


I love this script , and hope it could been tune-up ,but I am begin to learn for SU plugin codding , shame to less helping

[JClements]

TIG, not sure if this is how you intended the script to work or not.

Using SU8. If I select a bunch of standalone geometry and a couple of groups, only the standalone geometry gets project to the working plane. Each group has to be selected individually to be projected.

Everything should project I'll check into it...
Do you get the same 'error' with components too ?

[JClements]

Hi TIG:

Yes, the script works with SU8 and with components. However, the selection set seems to require that it include all of one type of geometry only, either: all loose geometry or all groups or all components.

Attached is the test .skp I used.

this could be extremely useful!! i will try it out later today! thanks Tig!
