is true, on several occasions have been very frustrating these examples

error

I solved the problem, the key was to use "mod.edit_transform.origin"
I leave the code in case anyone needs it one day

mod = Sketchup.active_model sel = mod.selection parert_origin = mod.edit_transform.origin entity_origin = sel[0].transformation.origin distance = entity_origin-parert_origin tr = mod.edit_transform.inverse distance.transform tr

😄

wow thanks Dan, I will take some time to study this code, worth but me several questions arise, I will try to solve the most I can on my own, thank you very much 😄

Nice!
I read that if the glass is pyrex and the liquid is like canola oil (Could be another oil),
there is no refraction.

this is correct if oil index and the index of the glass are the same
however both indices of refraction index will be different compared to air, so there will be refraction when light passes from glass to air or air to glass

That limit the size of your render to the size of the viewport. If you need highres images, but in the same aspect ratio of the viewport use the "Get view aspect" button and then lock the aspect ratio. Then you can increase the output size and still be relative to SU. So if you save out a 3000px wide image in SU and then render out a 3000px wide image in VfSU they match, no problem.

as it indeed, I was wondering if there is a vertical correction for the camera as in 3d max vertical correction at a vray camera or Guess vert, I've tried 2 point perspective but it changes the camera position and if I move it back the perspective changes 😕 . so my question is: is it posible to correct verticals (easy way) without moving my view?

Heads up to others: be sure to click on the arrows that take you to other places.

Nice bonus!

Get's the ComponentDefinition of the ComponentInstance or Group
definition = self.get_definition(entity)

Get's the bounds of the definition - note that if you get the bounds of the instance it will be a Boundingbox aligned to the model axis - not the instance axis. Which is why you need to get the definition bounds.
bb = definition.bounds

Now transform the points of the definition boundingbox with the transformation of the instance.
pts = self.bound_points(bb).map { |pt| pt.transform( entity.transformation )

In other words, get the boundingbox of the definition and apply the instance transformation to the coordinates of that boundingbox.

thank you very much Thomas and Tig that prompt reply! 😄

I will try to implement your suggestions right now

this is what I have achieved so far

entidad = %(#FF8000)[Sketchup]%(#0040BF)[.active_model.selection][0] curretmaterial = entidad%(#0040BF)[.material] nameM = curretmaterial%(#0040BF)[.name] curretmaterial%(#0040BF)[.color]=[102, 0, 51] curretmaterial%(#0040BF)[.name]=%(#BF8080)["nuevo tono"]

I shall be able then apply the recommendations

(sorry for bad English)

thank you very much for the help, great links
