Aha .. on that note, I have been seeing some errors with the closeness tool that I don't understand.. This is a copy and paste of an email I sent to Alex yesterday...
I wonder if you might be able to identify why I have these unusual results from the etAnalyzeCloseness tool.
The view is from underneath a tensile form (rhino file attached test tent roof 002.3dm (5.8 MB)) – I have used the develop tool to make the surfaces you can see in the screen shot. I then set the main tensile mesh as the reference, and selected all of the faces made using D.LOFT to be analysed with the 'closeness' tool.
I expected the results to be similar to the three panels on the left, where the blue stripe shows the obvious distance from the rounded form very clearly, but all of the other panels seem to have a common, rather ambiguous measurement, rather than individual for each panel?
As far as I know the panels were not created any differently to the three that share an expected result.
Also, the closeness figure is way out, I measured the deviation manually to be around 15-25mm from the ‘mould’ shape, but the readout gives 2230mm which is obviously totally incorrect.
Also, on the panels that do appear to be analysing correctly, the colour scheme appears to be the wrong way around (as I read it) – The blue is the smaller gap, which should be at the edges, but it appears in the middle which should be the greatest gap!?
Hope you can help me understand the problem here.
