I rework it and now it's a closed shell volume:

by these steps

1. I started wuth the car body

2. draw with line tool and close the volume
   

3. I copy and offset scaled by 1/16 inch as before with scaleGroupFloat_dj
   scaleGroupFloat_dj will create an offset call "shell". the settings shown ealier above

4 ) I then vector push-pull the wheels acoss

5) right click and used context intersect face to model

6. cut away
   
   and then cut the bottom interial face of the car

Is there a ruby out there that will create an offset or "shell". I have a car shell... 1/6" thick lightweight ... The problem is ... the programs won't simply print along a plane with zero thickness.

and now marvins
The Answer:
yes- Use scaleGroupFloat_dj.rb
and a vector push-pull tool
(=to SU push-pull then one end exploded face move by the move tool)
by the process above you get this
car+body16_dj.skp

It is true you may not need bounding box corner coordinate of a car in each image to make 3D models to 2D images,

I have some CAD cars and I need to project these 3D models to 2D images, is there a method to get the 2D bounding box coordinate of a car in each image? e.g., the 4 corner coordinates, (x1,y1), (x2,y2), (x3,y3), (x4,y4)

Yes You can turn 3D models to 2D images,

method 1) flatten it with scaleGroupFloat_dj Ver 1.6.5

when color leaves then it flat
recolor with in model texture

I use four boxpoints to four corner (boxPoint_dj)
then readed the c-point to target

method 2) a clip trxture - edit to transpaency background-input image

There is 2 methods beside mine above to get the 2D bounding box coordinate of a car.(x1,y1), (x2,y2), (x3,y3), (x4,y4)

method 1) Ruby ATI method is given here for bounding box coordinate
http://www.sketchup.com/intl/en/developer/docs/ourdoc/boundingbox#corner

method 2) If you have the SU Pro save a export to VRML and open to notepad, lookie here coordinates

I have a tool call cumulativeScaler_dj
it's part of scaleGroupFloat_dj package (doses cumulative xyz, x, y, z, scale,step,move and rotation)

I can't figure it out...all I have been able to do is an offset.
Looking to basically create a 1/16" shell.

I figure it for you.

I found a car body on 3d warehouse

and I work it 1/16 but it's not close yet for a volume

car+body16_dj.skp

My plugin will make a shell

I wrote a plugin that will rescale your door call
scaleGroupFloat_dj, try it, it's free.

I try it on your skp file and it work for me.

Well that all
good luck

"I rotated the circle half the angle between vertices. I used a default 24 sided circle so I rotated the circle 7.5 degrees. I drew a line along the red axis to to split the circle in half and deleted the bottom half as well as that diameter line."- Dave

Hey I found this tool

Point Merger Tools v 1.2
(25.81 KiB) Downloaded 1021 times


I would like to have your example
but since i don't here
you can soften inter edges to make two surface of the mesh terrain
select inter terrain
max distance of gap

now it shoud be good

if the poly code count to high it will also lower the count, then do what I did above

Do you have a example jpg you working from

Here one I found

Sorry I don't own a mac

Not all api codes run on the mac.
cmd=Sketchup.send_action 21939;#mac 57637 is one of them (Pc paste in place, Mac paste)

If this dose not fix it, I need to know the line #no of the error please.

I have releaed the new version at the above downloads (Another_Sketchup)

I build it with
scaleGroupFloat_dj v1.6.5 bata
cumulativeScaler_dj
push pull - cumulativeScaler layers -scale

frist four frames is meathod 1 )cumulativeScaler layers steps 1X
others frames is meathod 2) cumulativeScaler layers steps 7X
last two frames is copy invert meathod

erase the cut line and bridge line

fleur_dj.skp

erase the cut line and bridge line

top surface can be rounded by follow me tool

If you give your skp file I can build it with
scaleGroupFloat_dj v1.6.5 bata
cumulativeScaler_dj
push pull - cumulativeScaler layers

1. put your patten on a flatten cylinder-push pull vector_scale tool_trim outside off
2. stamp to mesh - sandbox tool
3. copy and invert -scale
4. paste in place and trim outside off

This is my best tip all year of 2011
by dukejazz on Mon Dec 19, 2011 7:52 am

When sketchup starts up it doesn't see any hidden ruby files

(note: With windows explorer toolbar, Tools-folder options-view-show the hidden files = on)

You can hide what you don't need to load, and unhide the require ones that you do.

Later with Jim ruby toolbar you can load the hidden ones.
That's because your telling the script loader about the name, type and location of ea. plug-ins to load...

thus no need to double buffering of plug-ins in folders by loaders.

Also the plug-ins are in the folder that are meant to be in.
win win!

" locations (on the terrain) as the photographs, it's difficult to be sure of the scale and relative distances for the new features."

ANY TIPS? Yes

tip 1

file -imput-ipg-use as image

explode image
right click
context - texture -position -(pin tool to make squared)

example above is done on a side view
but you can do a top ang down botton view too.

tip 2
scale with my tool

scaleGroupFloat_dj Ver 1.6.5
Copyright Feb 15, 2013
DukeJazz: by James Cochran

drop boxpoint_dj on image plain
select both group,make a new group and scale with scaleGroupFloat_dj
rotate plain to prospective and then re-flatten view by resizing to .00000001 depth of plain size and then explode (all can be done in scaleGroupFloat_dj)

place a SU model in the context of a photograph.

it should fix the size alinement problems

Update:
Feb 15, 2013; scaleGroupFloat_dj v1.6.5 bata
-add cumulativeScaler_dj rotation around

Feb 4, 2013; scaleGroupFloat_dj v1.6 bata
-add cumulativeScaler_dj move around (a step boxpoint)
-add cumulativeScaler_dj size lenear stepper
-add cumulativeScaler_dj move lenear stepper
-fixes

Alternet way to restore toolbars prosition
without using veiw-Toolbar - save toolbars prosition (reg ToolbarsUserCustom-Bar)

Ok you know that everytime you boot sketchup the tool bars are set the same as you left
right

now if you move thing around and if your tool bar get mix up by resizing sketchup bordders and you want to restore toolbars prosition to a standard view (veiw-Toolbar -restore toolbars prosition is ok to use)

but

To return to how it was when you started, just start a new sketchup instance then exit out the old then exit the new.

when you come back toolbar are fix to how they were

I re-read what you wrote and my ealier statment is wrong
the edge would switch on in going thou the
model with textures or shading the lines
and in the hidden line, wireframe, back edges or x-ray
view the view goes completely white. See the screenshots below

but
if profile were off
add hidden geometry were off
edges are made to guides or smooth
you will see what you stated sgcrain » Yesterday, 12:59 pm



if this not the case

A fast fix next time is using your undo's back beyon the problem

or restart another sketchup with out closeing the old

copy model or object to new
and
save old model and close old sketchup

in new
if it problem go's away it a style problem or state of sketchup

if it dosn't goes away its a material problem (transparcy on and style edge is by material)

now when you close the new it refresh reg back to before the old sketch up started
which is good
But
now if you alreadly closed sketchup before starting a 2rd sketchup
you can load a different model
or reload a new style
if the problem still their
maybe now you have to reinstall sketchup reg by reinstall sketchup

I which you did.

I think it was menu- view- edge style-edges was turn off

The outliner isolation:
Make all connected to a group, then enter the group edit mode and make sub isolated groups. Open outliner and dragged your isolated selected groups to above top untitled area to Isolate Selection and when done editing drag back or explode if need.

"EarthMover" - dukejazz
"Isolate Selection" - Yes (Tip_dj)

"Looking for a plugin that" - No, not a plugins sorry

"will isolate whatever is selected in an isolation" - Yes

"mode and conversely exit out" - Yes

"isolation and bring back all of the non isolated items."- Yes

"If possible, when exiting isolation mode, the tool will not affect any previously hidden geometry (geometry hidden prior to enter isolation mode)"- Yes

"I think currently there are a few option to hide unselected" - Yes hide by context hide

", but to revert requires" - Yes select hidden by context _ unhide

one to unhide all"- Yes select all and hide by context hide || unhide

Results:

"probably be quicker than via a script-TIG"

My point, the outliner is very good tool to have open and to use.-dj

a ruby outline
left button mouse down draw circle
left button mouse up make a group
finish with move tool then rotate edege
