feature request: show number of internal planes

Recommended Posts

Hi community (especially Daid ;) )

I've been dabbling with Google Sketchup 8 and have made quite some models by now.

When I generate the STL and open it with Cura, I usually have "bad" internal planes inside my model which are not supposed to be there -> the red stuff in X-ray view.

This feature helped me a HUGE lot in making my models in a way that they are "good", without any red planes. Sketchup probably has some quirks there as it often places 2 identical planes when there should be only one. This gets me a "red plane" in Cura.

Now, lately I've had the problem that these red planes get smaller and smaller, and my models get bigger and bigger. So it can be complicated to spot a tiny red polygon in Cura and I have to look at every corner very closely.

Now, here's my request that would help me (and hopefully others, too) a lot with that:

If there were a display in X-ray view, showing the amount of red planes there is on the model, this would make fixing my models much easier because I always know how many planes there are which need to be fixed.

Something like a "There are X internal planes in this model" text displayed in the bottom right corner or somewhere.

Maybe make it only appear if there are any internal planes at all, and to be really thorough: make the text a link to the X-ray view.

I guess this should be fairly easy to implement, but let the programmer be the judge of that ;)

There should be a "next error" button where you click the button and it zooms and centers the view on the next internal plane.

However be aware that you can also have "holes" in your model - like tiny windows where two edges don't quite meet up. I am only able to detect these in layer view where it won't fill a particular layer due to a windows over on the side. Cura can't detect these because it's hard to tell if the holes are on purpose.

That would be awesome - but probably also take considerably more effort to implement. Simply counting the red planes can maybe be done by actually counting every time the renderer draws a red surface, and then showing the counter on the screen.

But as I already said - I don't know the program code so I leave that up to the programmer :)

The holes are a different story...

My "routine" is: Check for red stuff (which takes a lot of time that can probably be reduced without much effort), then check for holes with layer view.

It would be nice if any "ignored geometry" (because it's thinner than the nozzle) could also be highlighted in another color. But that's a much bigger feature request than what I intended...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
