[Plugin] RotaScale

free agent

wow thom thanks for working on this i really appreciate it!!

is this something I cant do by using first the rotation tool and then the scale tool?

its way more than that, the point is also to control the point a group will scale from, rather than just the centre or the corners, it makes lining/scaling reference material up to a model (or vise versa) really quick, so it squashes rotate scale and move into one.

thom just looked at the ruby, i works perfect, better than what i had asked for actually, i frikken love it i cant tell you how long ive wanted this, thank you.

oops first problem ... it seems you HAVE to rotate, if the first line is on an axis then it wont let u place the second point along the same axis

Yea, I expected there to be issues. I didn't test it much. I uploaded a quick update. Think it should take care of that problem.

it does work in some cases, don't know why

Can you explain further to what you're doing? I can't reproduce any problems.

Damned good! (works in V6

beautiful, thank you, now it works great, i dont see a need for improvement

Thanks for checking that.

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

pilou

Maybe a suggestion
Scale is XYZ, maybe useful to have also choice X,Y only!
written in the todo list

Seems there are Splat bug when Undo v6 ! (but not repetitive)

Yup. That can be done.

You can yet make this after the rotate scale with the same tool
3 click more and have a resize as you want
here half size wanted
bug splat don't come back in the v6...curious

Let me know if it comes back.

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.

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)}")

...

thomthom

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?
