Open the Styles window,
Go to the Watermark section (fourth button from the right, big OK on it)
Insert watermarks/backgrounds

Thanks Thomthom!
I found it.
More details for those who may run into this problem again: After opening the Styles Window, clicl the Edit tab. The Watermark button belongs to the Edit section.

I download this model from 3dwarehouse.

It's a Dynamic Component Interactive Cube House made by Henry Kropp
There is something make me notice: When I click into a group to activate it, all things outside the group disappear (not change into the grey as usual). How to do that?
Thanks for your attention!

Here it's the link to the model made by Henry Kropp in 3dwarehouse.

Could anyone tell me how the author put the image as a background behind the building model (not to paste the image on a face behind)?
Thanks for your attention!

Hi all!
As you know, SU has a command allowing users to divide a line or arc.
I want to divide a cubic bezier curve (drawing by a tool on the BZ_toolbar) into equal distances, but can't find a tool to make that. Any help?
Thanks for your attention!
Best regards.

Hi all!
While playing with Copy along path plugin, I met a problem:
The plugin runs an array of component along a path starting with one end of the path.
This end is understood as the start of the path when I draw it.
In case I want the array runs in the opposite direction, I need to change the start of the path.
How could I do this without drawing the path again?
Thanks for your attention!

Hi Chris, Hi All.
I used the plugin to make an array of component along a path, but it only create one component at the start of the path and nothing else.
I don't know what i do wrong. Any help?
One more thing: The plugin don't give me a choice of inputting distance between components (like Copy to spacing in Copy along path plugin). Or I miss something?
Thanks for your attention!

i guess you need to plan ahead next time .

That's your right to guess.

Hi Jean Lemire, hi xrok1.
Thanks for yr tips.
Your method is good move in case the group is simple.
If the group is very complex, containing many objects or other groups in it, or in case you need to divide a group into many continuously, I'm afraid of that your method is time consuming and I would consider it if I had no other choices.

Hi all!
I'm new to Sketchup and while practising it I met some problems that I need your helps

1. How can you divide a group into two groups?
   I use a face to divide a group by the intersection tool. Then I have two parts of that group. I can erase one to get the rest. I see that is the way it works in Sketchup. But I want to keep two parts after dividing and they separate from each other into two groups. I mean, is there a way or plugins to do this automatically?
2. I draw a big building model and take in it a lot of details, following the type of BIM (Building Information Modelding, something like that). Now I have a big trouble. The file size is very big, though I have only done a half of work.
   I wonder about ways to keep it as small as possible.
   I already did some methods, for example, using Purge used, using the layer manager to control visibility. But I have feeling that I miss something out there.
   How about Xref Manager or something like that? I tried but the file size didn't reduce.
   Your advices?
   Thanks for your attention.

You can do it by scaling the edited group using the tapemeasure tool to pick the desired dimension and typing in 4200... but the width and handrails etc will all scale too - so not such a good idea.
Best to edit it by dragging the top parts down at a rake [use guide lines] to about where you want and remove some mid-sections to suit - it's even made in pieces to allow you to do that [you'll need 7 of the 14]! At the end it'll be a few mm off 4200mmm - it is an imperial escalator after all - use the tapemeasure scale trick with 4200 and it'll grow the 9mm needed - accurate enough, I suspect ![attachment=0:1qovrtn6]<!-- ia0 -->Capture.PNG<!-- ia0 -->[/attachment:1qovrtn6]

Thanks TIG for your quickly reply. (And btw for your plugins, they're very helpful)
The idea of using the tapemeasure tool is not bad, if the distant difference is small.
I don't understand the second method that you adviced. My English is not good enough. Could you please help me clear its meaning by some images?
Thanks
Best regards!

Hi all!
I downloaded an escalator from 3dwarehouse.
It's not in dimensions as I wish. So I want to scale it, for adjusting the height from the lower level to the upper level.
As you can see from the following picture, I want change the coming point of the escalator from level A to level B.
I met a problem while scaling the escalator object to achieve that goal. The scaling box wraps all over the object, so the handle grips are on level HD (handrail level), not sit on level A.
How can I make a precise move from level A to level B (just scaling along the blue axis)?
Thanks for your attention.

Usage: export_by_layer(type)
Typed in Ruby Console or another script...
Exports everything in the active Model into a set of files 'by layer',
put in the Model's folder named with the 'layer_name' as a suffix.
The argument 'type' sets the file export type...
e.g. type = 'obj' [as a string inside '' or ""] other types possible e.g. 'dxf'
Faces with their Edges on another Layer take those Edges with them...
For example: export_by_layer('obj')
[attachment=0:144rdr3z]<!-- ia0 -->export_by_layer.rb<!-- ia0 -->[/attachment:144rdr3z]

Firstly, thanks for your work in this problem.
I wonder how it works. I don't see the icon or something like that in Sketchup menus or everywhere to active it. Could you give some tutorials step-by-step?
Secondly, I see there are few choices when exporting sketchup into cad while still keeping layers alive, especially when export sections.
Any help for this thing?

thank you!
I will try. Hope it works

Hi all!
I have a shape as shown in the attachment file below
I want to make a section through it as you see in the picture.
How is it possible in Sketchup?
Thks for your attention!
