Am I going nuts? [found, thanks]

Thank you, John, I tried the second one and the scaling worked almost perfect.

By the way, Frederik pointed me to the script I was looking for: It's "Bring my View Back" by Tomasz Marek:

Now I need to find the most efficient workflow.

Seems you have also a plug by Chris Fullmer "Perpendicular face tool" that allow you to draw a square, a circle, or any surface at the end of a line

Wow, thank you, Pilou, this one comes in handy, too.

Update: A combination of TIG's line and Chris Fullmer's "Perpendicular Face Tools" seems to be the ticket.

I am glad you have found the plugin. You can modify the distance

user_dir.length=2.0

. I have used the plugin even to cut-out an opening for a proposed building and has left the plane at the standard offset.
It was like doing a photoshop mask in SU . I could then export a photomontage straight form SketchUp. There is an issue with such a method when the Sun points towards camera, cos the photomatched plane gets too dark in relation to the model itself.

Hi, Tomasz, thank you for your great work with the KT exporter. At the end I decided "Bring My View Back" was the quickest and most precise way to add a background. All I needed to do was change the axes of the component and then I was able to scale it as I wanted. I'll post a video tutorial soon for anyone interested.

And I found a way to solve the problem of the sun and sky interacting with the background plane when rendering in Twilight:

This means now I can use an HDRI or physical sky + sun for illumination, and another image as a background.

my name's not "Frederik", but I'm flattered you would confuse us.

Here is a new version 1.1 for you. No need for changing axes

Wow, thank you very much, Tomasz! Please, mods, add this to the ruby index. And thank you, Shane, for pointing him to this thread (I can't explain how he'd find about it otherwise).

Do I understand correctly that you want a script to draw a guideline from the camera eye position 1m towards the target ?
If so this line of code pasted into the ruby console will do it...

m=Sketchup.active_model;v=m.active_view;c=v.camera;e=c.eye;t=c.target;e1=e.offset((t-e),1.m);m.active_entities.add_cline(e,e1)

???
To make it a solid line change the text 'add_cline' to 'add_line'.

Thank you TIG for this piece of code.However it seems that executing it, doesn't draw the line...(I am on SU 7)
Another little question (I am such a ruby noob Is there some template ruby file where I can paste this code in so it becomes a .rb file I can put in the plugin folder?

Thank you in advance,

Chris

Works fine for me in v7. You won't see the cline unless you change your view as you are looking straight down it...
You need no special 'Ruby' file - just make a plain text file (xxx.txt) with Notepad and change it's sufffix to .rb (xxx.rb) - on a PC you must have filetypes set to display their suffixes...

Putting in plain code would cause problems since it'd run as soon as the script loaded as soon as the model opens... So you make a 'def' so you choose when it runs [I'll keep it simple and miss out Modules and Classes etc], thus:


def clinefromeye 
  model = Sketchup.active_model
  view = model.active_view
  camera = view.camera
  eyepoint = camera.eye
  targetpoint = camera.target
  eyepoint1m = eyepoint.offset((targetpoint-eyepoint), 1.m)
  model.active_entities.add_cline(eyepoint, eyepoint1m)
end#def

I originally abbreviated the code so it was in a one-liner - above shows the same code but made more readable - note that the #=='comments' and previously ' ;' were=='newline'...
To run it now type clinefromeyein the Ruby Console...
To add clinefromeyeto a menu or toolbar... I suggest you see other scripts for examples...
