SketchUp calculates incorrect area
-
In addition to the disabled context menu in the material browser for the Area command (http://www.sketchucation.com/forums/scf/viewtopic.php?f=11&t=15971), I found another bug:
See http://www.sketchucation.com/forums/scf/viewtopic.php?f=180&t=16075 for example file and description. SU calculates the areas differently.
The Material Editor -> Context Menu -> Area gives a different number from what Entity Info gives when you select the face the material is applied to.
However, if you explode the component in the sample file I posted, Material Editor -> Context Menu -> Area gives another number, the same which Entity Info gives. -
No feedback on this?
I've made a .skp example that might explain it better.
What I've done is start out with a cube 1x1x1m and grouped it.
Then I made a copy which I scaled 2x along one of it's axes.
When I then make a copy of the scaled group, open it and rotate the geometry inside by any number of degrees, the area for the surfaces are not calculated correctly. If I trace the face on the outside of the face I'm given the correct area. If I explode the group I'm given the correct area.So it seems that when you modify geometry inside a group which is scaled non-uniformly the areas are not calculated correctly. Not the Query tool plugin that comes with Sketchup, nor the Area method of materials.

Thomthom:
I know this is a late reply, and may not be directly related, but after modeling a building with simple planes, I tried to do an area take off of roofs and walls using the native tool for this and found it to be significantly inaccurate. I don't think I went through the same process you did to discover this, as, at the time I was in a developmental stage with SU. Actually, I am in a developmental stage now, and probably will be tomorrow, too. ( thinking "not sure when i will get over it") -
Are any of your groups/components skewed?

T:
At the time that I did the model, I think all of my groups/components were screwed.
Whups, you said skewed. Yes, this is possible. But at that time, I was not sufficiently knowledgeable about groups and components, let alone layers.
Actually, the building was rather simple. Of course the roof planes were sloped, but no other real complications.
