Thickness Ruby to make shell?

marvins_dad

I've been doing a lot of 3d printing lately. Mostly the volumes have been a modification of something or simple volume.
I understand that in order to get the object to print properly it needs to have a completely closed volume.
The question I have for you guys after searching and not finding a solution...
Is there a ruby out there that will create an offset or "shell". I have a car shell that I am working on that I want to print as a 1/6" thick lightweight shell to attach to something else...similar to an RC car shell. The problem is that I have created the shape of the shell I want, but the programs won't simply print along a plane with zero thickness.

Any ideas?

Thanks
antoine

I have that installed...will try it at lunch...initial attempt crashed the program, but maybe if I am more selective it might work.

Thanks Rich

And there is Thomthoms shell plugin.

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

Thanks

Looks perfect...but can't get it to do anything.

did it crash or appear to hang?
if you're doing a processor intensive operation in sketchup, it may appear as if its not working.. but it is.
(for reference, I once did a jpp operation that took 4 hrs to calculate)

gilles

works with groups or components, did you try on raw geometries?

I get a "SketchUp Application has stopped working" dialog box...only options are check online and close or close program. Problem signature:...APPCRASH

I was trying with raw geometries...I'll try with a group...are you talking about "Shell"?

marvins_dad

Shell seems to preview when I select a group and I can see the offset and adjust it. When I double click it doesn't stay...when I hit enter nothing happens. When I double click then click outside the group the offset disappears.

What am I doing wrong?

gilles

I do.

Adjust the fitness, then Enter, then double click.

Okay - I tried on a portion that wasn't as complex and it worked.
Looks like I need to simplify my model a bit (clean it up) and try again.

Thanks!

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 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

dukejazz

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

by these steps

I started wuth the car body
draw with line tool and close the volume
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

cut away

and then cut the bottom interial face of the car

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
