bug splat don't come back in the v6...curious

Let me know if it comes back.

Hi Thom
When I point the 3rd point with (let's say) cntrl key pressed the script should't change original scale. Could you add this feature? It would be nice imo.
Thanks

It is done.

Hi, im sure this plugin will make things much easier, thanks!
I think it would be even more if pressing "ctrl" button would cause "RotaScaleCopy", the way it works in typical rotation and move tools.

TIG

Thanks for a great idea and an already very polished tool...
A minor problem - there are error messages in my Ruby console relating to the

float.round_to()

method.
This is not built in to Ruby - the nearest is

float.round

, I assume you have a round_to.rb auto-loading... perhaps you should include the method code inside your script, I'm sure others will be getting the error ? Here's the code I used to fix it on my PC...Float-round_toEtc.rb - it also includes some other methods like float.floor_to etc...

thomthom

I thought it was a ruby method. I googled ruby and rounding and I found some references to float_to which I just tried, and it worked. I guess it's a plugin I have installed which added that method.

Thanks for bringing that to my attention TIG.
Though, if I implement this method, might I not risk causing conflict with other script that also implements this method? I suppose if they act identical it might not be a problem..
...this is why I don't like extending base classes...

TIG

I expect it'd be an identical function anyway - I'd change the base class in this case, as it's a pretty safe bet.

You could always call your own version float.round_to_TT [or another weird name] that no one else will use AND then find+replace .round_up with .round_to_TT ? OR you can invent a safe and simple internal def something like:

def round_to(float,x)
  return((float*10**x).round.to_f/10**x)
end

typical usage would then be...

view.draw_text(screen_xy, "Angle; #{round_to(angle.radians,1)° - Scale; #{round_to(scale,3)}")

...

Updated the plugin in regard to TIG report. Thanks TIG.

The no Scale on the Z axis will be released?

thomthom

Not sure. I don't fully understand the API on transformations. Need to figure out how first.
I'm currently working on a couple of other plugin projects, this was just a quick distraction.

Chris Fullmer

t = Geom::Transformation.scaling point, xscale, yscale, zscale

just use 1.0 as the zscale value and it will be good to go!

If I do that, it works for points that are picked planar to the model X and Y. But if I pick a point in the model Z axis, things are still being scaled only in the X and Y. Maybe that's what people expect?
IMO that not what I'd expect from this plugin. I expect that if I pick two reference lines in the Z axis, things will get scaled in that direction.

...I suppose that the scaling transformation would have to be transformed to be local to the reference lines?
That's what I'm not sure how to do. Getting the plane of the two reference lines (what happens when they are co-linear) and crossing it with the scaling transformation?

Minor update to address a problem where V-Ray for Sketchup would not render RotaScaled groups/components correctly.

thomthom

Spotted a potential bug. Corrected.

hi 5

thomthom

5!

hey thom thom, looking at this script i see uve put standard rotate, as a extra when holding control u get standard rotate, any way we could get linear scaling when holding alt?

thomthom

I'd think so. Just need to find a spare moment.

Can I suggest an update to this plugin? Wouldn't be more useful to have the "Move" function too added to Scale and Rotate? This can be done with 4 clicks instead of 3. First two to pick the "source" vector, and two more to say where to put the "target".
One can always reproduce the current behaviour, by clicking on the same point for the first and third click.
And, as a final enhancement, it would make a Copy, if the Ctrl key is pressed.

I've had the same thoughts - will add it to my To-Do list.

And a random function of a selection? Rotate + Scale
Edit
In fact exist in a certain way by Chris Fullmer Scale Rotate Multiple
