Zoom Selection

Jim

ok, this is what happens to the script: if i am inside of a group/component and 'hide rest of model' is on, zoom selection does not work. surely this must happen to everyone?

You are correct, it does not work. There are 2 ways to zoom to a selection using the API and they both fail when "hide rest of model" is enabled.

I'm not seeing a quick solution other than Matt's idea of temporarily switching 'hide rest' on, zooming, and then switching it off again.

I'm sure a better "Zoom to Selection" could be written, though - one that would work in all configurations.

Jim, you mean if a script was written from scratch it could be done?

Yes, a camera zoom is simply moving the camera closer to the target, and can be done using Ruby.

Please, Jim, tell me how to move the camera to a selected item with distance of 2 meter by ruby script.

Jim

model = Sketchup.active_model
view = model.active_view
camera = view.camera

eye = camera.eye
target = camera.target
up = camera.up

vector = target - eye
vector.length = 2.m
eye = eye + vector

camera.set eye, target, up

Unbelievably, Jims code moves my model. Thank you very much.

I have to play a lot, because I don’t understand, what the code makes. Repeating brings my model nearer and nearer. Change the unit from 2. to 2000. makes bigger steps. Change the unit from 2000. to -2000. turns the direction (the model goes remote).

So, how can I see one part of my model with distance of 2 meters?

I think if the last 4 lines are

vector = eye - target
vector.length = 2.m
eye = target + vector

camera.set eye, target, up

then you will get the desired result

Sometimes RickWs code works pretty. But often it does not work. Then sometimes the error is:

Error: #<ArgumentError: (eval):197:in 'set': Eye and target points must be different>

My goal is to select one item by name and to show this item with camera with distance 2 meters.

To make it work, I had to »Start Animation Observer«.

@Rick
Your code works properly. Thank you very much.

if i select something inside of a group it does not work - but will fit the contents to screen if nothing is selected.

What do you mean with "It doesnt work" ? What do you want it to do?
If you are inside a group the group itself isn't selected.
My script zooms in to whats selected. Inside group or not.

Thx a lot! Great plugin. Work fine, no problem with selection zoom.
Can you recommend me any other useful plug?
