... and the ScalerDC 'change' jolts the contents into recreation, with corrected scaling.

Thanks TIG, I appreciate the help. I think I'm going to have to do some thorough testing to get first hand experience with it.

Dependent on the axis orientation (say a window that utilizes glue to), does the ScalerDC have to be in the X axis or will others work? Just trying to get a better and more thorough understanding of exactly what it's doing.

Hi TIG, When I ran Descaler it successfully descaled all components but gave all my components unique names. Components are all either circles or simple 2D blob shapes, lying flat. Is this a bug? Or is there a way 'round it?

ANY change in the 'position' of ScalerDC jolts textured faces into being 'rescaled' back to normal if the 'parent' DC is Scaled.
If you look at its formula: X =parent!X-parent!X - it effectively sets X=0 which is where it is initially placed: any change to its X, Y or Z should have the same effect.
I not sure 'why' it works... but it does

It always makes the 'descaled' instance unique.
BUT you can edit the script TIG-Descaler.rb using a plain text editor like Notepad.
If the lines starting at line#71

if c.is_a?(Sketchup;;Group)
  defn=c.entities.parent
  c.make_unique if defn.instances[1]
  defn=c.entities.parent
else ### it's a ComponentInstance
  defn=c.definition
  c.make_unique if defn.instances[1]
  defn=c.definition
end

Change it to read thus:

if c.is_a?(Sketchup;;Group)
  defn=c.entities.parent
  #c.make_unique if defn.instances[1]
  #defn=c.entities.parent
else ### it's a ComponentInstance
  defn=c.definition
  #c.make_unique if defn.instances[1]
  #defn=c.definition
end

That way the lines starting with # are ignored and the objects are not made unique !
BUT note that if you have several instances with different scaling then the end results might be unexpected...

Thanks very much TIG - I'll go off and test it on some components with diff. scaling and see what comes up.

These are for plants as my numbers are climbing into the 1000's (and soon into the 10,000s) so I export to Excel/Vectorworks for counting etc.

Hi TIG
I'm running SketchUp Pro 2015 (Version 15.3.331 64-bit). I installed this plugin and tried right-clicking on one of the scaled Dynamic Components I have with messed-up textures. But I don't see your plugin.
Might it be buried somewhere else not obvious?
Has something changed recently with Sketchup which keeps it from working?
Thanks.

If you read through the thread... unfortunately it does NOT process Dynamic Components.
Any subsequent change to the DC would immediately mess up the [re]textured material.
You can try exploding the DC, and then regrouping/re-component-ing - without DC attributes...
Then it will work...

I'm only finding about this plugin now. So it's basically a reset xform for Sketchup?

hi there,

im currently struggeling with 3d warehouse models.. some of them scaled wrong and consist of groups components, scaling them down is no problem to have the right size, but to avoid rendering issues wirth third party apps etc i want all groups and components to be 1:1 and not scaled.. so i come to use your plugin which processes nested entities, however, there are 2 problems...

first: if the mothercontainer is not scaled, but its children, the plugin does not show in the context menue ...

second: in contrary to fredos "scale definition" descaler kind of breaks uv mapping:) .. (most likely due to processing entities like faces and lines too?)...

would be cool if these issues could be adressed in a future release

best, franz

hi TIG and hi to all the readers!
I'm finding very useful the TIG's trick for keeping the scale of the texture!
I'm now struggling with same topic on a curved surface, but seems like the trick doesn't work....
Could you help me out please?

texture trick on curved surface.skp

TIG

I don't think it's suitable to do what you want.
Can you explain [in simple steps] what you have, and what you'd like to achieve.
I can't understand your 'containers' and materials on faces etc exactly.
Why isn't the material on the curved surface, rather than the instance ?

Also your component seems to be a DC... and if I copy an instance of it, then a new definition gets made for that copy...

Hi TIG! Thanks for you quick answer!

So, what I'm trying to achieve is the possibility to change the texture applied to the component, so that in my render I can replace it with whatever texture and it gets rendered fine, without the need of entering the component and map the surface. This because I assume I will be using the same component a bunch of times, I have the need to have it reported by the SketchUp report tool, but I want it to be aesthetically different, so I'm keeping an inner component which is actually the same, and an outer shell which is painted with different textures (materials).

I've already achieved this in the file I'm attaching (it's a DC, see how it works in the options window, sorry it's in italian), working with a flat plane. Basically one have to set the dimensions, create a sketchup material using a texture with the desired dimensions, and apply that material to the face, which automatically gets mapped on that face.

I'm trying to figure out how to do the same thing on that hell of a curved surface

grafica CoverUp.skp

TIG

The only solution I can see is a manual one.
Explode the scaled instance and immediately make a new component from it ?
It keeps the scaling etc, transferring the material to the reused surface...
But any DC-ness gets lost !

pibuz

Thanks anyway TIG for taking your time to answer!

Thanks a lot, TIG
It's been 10 years...
I think you need to replace the lines
ts=Geom::Transformation.scaling(ct, 1.0/tx, 1.0/ty, 1.0/tz) c.transform!(ts) ### reset scale
with
c.transformation*=Geom::Transformation.scaling(1.0/tx, 1.0/ty, 1.0/tz)
Because when there is a rotation transformation, it does not work correctly
