All the solutions you guys provide are worth using, however I’ve cycled a bit through all and I can’t get a workflow that solves all the work I have to do.
I have tried right-clicking and retrieving area, but as I might have made mistakes and painted a backface or a group, I can never trust the results. My work is never linear. Selecting faces by material and retrieving areas from Entity info doesn’t give double areas as it only counts front faces, ignoring the back faces. It’s, therefore accurate but tedious. I have to manually redo all the work every week and several times if I find something is wrong with the drawing.
If I divide the resulting area by 2, I’ll always get half the area measured in sketchup. Isn’t it?
That way, if I have correctly painted faces, the area will be half than what I needed.
As I might have some correct painted faces and some wrong I cannot trust the results, or can I?
Maybe it would be possible to simply exclude backfaces from calculations. Most of us are careful to orient faces while modeling as they create all sorts of issues on rendering and even on sketchup display. There are a lot of plugins to easily fix these faces and we architects also use some styles that do require them to be correctly oriented.
We do require painting components so we get variations on the color/textures of multiple instances of the same component.
So in a lot of required situations materials are correctly painted on the component.
You’re right on translucent materials but sometimes even those have errors as backfaces are always hard to check.
My naming schema is quite tidy:
- I have materials for display and work that always render nicelly - No prefix
- I have materials for hatching X Prefix
- I have materials for symbology Y Prefix
- I have materials for area counting Z Prefix
It’s the modelling that requires a lot of different uses and so it’s always confusing and hard to follow leading to some workflows that are not as ideal as you correctly point out:
- Arch Modelling;
- Consultants/Engineer Overlays;
- Photogrametry importing/exporting…
Please don’t get me wrong, I can’t thank you enough for the interest and help you guys are giving this issue of mine.
