Lost edges importing dae file via Collada to THREE.js

chrisglasier

Original skp model - thickish edges

Imported into THREE project - no edges

Imported into THREE editor - white edges

Imported back into sketchup - thinner edges

I hope the images are self explanatory.

If anyone can give me a hint what's happening here I would be most grateful ...

Can we have the original SKP ?

Looks to me like the original's various faces might be separate containers - groups or component-instances ?
Hence the thicker profile edges in the model's Style.

When imported [as DAE?] into this 3rd party THREE app I suspect it just doesn't display any edges - although they are still there - as it shows when it's in edit-mode.

I suspect that the DAE/THREE processing merges the original 'containers', so that when it's reimported into an empty SKP those edges are no longer profiles and therefore the Style displays them thinner - except when they form a visual outer edge where these are again thickened...

Thanks TIG. Here's the skp. I think the thin/thick lines may be a result of my changing things to see if the scaling was the problem - ie perhaps not comparing like with like. No edges is what really matters to me.

Will have to check in again tomorrow ... GMT +8 here

simple rectangle pulled up for test

I think this http://stackoverflow.com/questions/25912104/three-js-draw-edges
might have some useful stuff about it ?

Thanks again TIG. I had a look at edges helper but I don't think there's anything there (at least that I can understand!). I posted http://stackoverflow.com/questions/43152833/sketchup-model-collada-three-js-no-edges. Maybe it's more a Threejs oriented question.
