This is the pretty version with pictures [by Rich] http://sketchucation.com/resources/tutorials/811-setting-security-permissions-in-sketchup

Unfortunately your EXTG and PROP groups are very very complex, and have many faces and edges that are almost coincident. The native Solids Subtract tool will let you take one from the other, BUT the results are made non-solid, with 0.0 volume. Because CutNfill relies on these tools, that is why you can't get meaningful results. SketchUp's built-in tolerance is 1/1000" and any edges that would be shorter that that are ignored, as if their end/start points are coincidental, but the tiny gap is not 'healed'. Consequently, any faces relying on such missing tiny edges will fail to form, and the result is a non-solid group with 0.0 volume. So you need to make your modeling much simpler and ensure that this tiny geometry issue is sidestepped. In real life cut and fill is not an exact science on site, so any approximation does not need to be perfect.

Very particular thing!

Simply perfect, TIG!!!!! Thank you so much for taking the time to do this no matter how simple it is; you're a bloody gem!

very nice TIG: I love this stuff: I was wondering if you could take a look at separate Ruby using Voronoi Tesselation I found some code that might help but needs Ruby interpretation. http://bl.ocks.org/mbostock/4060366 Cheers!

This a very useful tool but I think it could be better if we could see the mouse pointer, by adding this 3 lines in the code : def draw(view) @ip.draw(view) end#draw Thx

Thanks for the reply, your plugins are amazing and some of my most frequently used! I must donate when I've got all this work out the way. You're a total star TIG!

I think I now understand your issue better... Whether a section-plane appears in a scene-tab or not, is controlled by each scene-tab's settings. If if is set up right it should show the section-cut in the newly added elev-tag scene tabs - which will have been copied from the tab's settings current when they get made... To add a missing section-cut to a elev-tag's new scene-tab you simply need to activate the section cuts' visibility and activate the desire cut [then hide the scene-tabs], then remember to update the relevant section-tab to see the section. You scene setting's can be set up to NOT copy many settings over, check yours are set up as you need them... I don't that this has ever been more 'automated' in this toolset...

@tig said: I worked with Tasmania Uni on 'SuperSlob'. It creates CNC cut interlocking ply panels for buildings, exhibition-stands, furniture etc in SUp... I did the SUp Ruby panel-maker, detailer and CNC stuff... [aka: 'Castle'] http://anzasca.net/2012papers/papers/p33.pdf http://www.design-island.com.au/wp-content/uploads/2012/04/Castle_DMTbrochure.pdf Now that is some extremely efficient use of space...

Very useful tool, thank you! [image: pgFx_.gif]

Okay, solved my own problem - -Copy Comp A -Make copy unique, rename as appropriate -Open copy and select all nested components -Make unique This preserves all relationships and renames all the components without having to select each group of components individually. Minimum number of clicks. A plugin would save me a couple of clicks but I can live with this. Kris

The latest version works fine for me too, across all newer SketchUp versions. What is your exact issue ?

@yeehaa123 Thanks a lot, this really helped! The previous version sometimes not only 'reset' the scale but also distorted the geometry of objects. With your suggested change everything works as it should now. Much appreciated!

Dear TIG Thank you for the suggestion. May I humbly suggest that if the plugin could be coded to .... "remember" the Groups/Components selected by the user "remember" the splitting plane defined by 3 points by the user then carry out by "repeating" the splitting action to the Groups/Components one by one? I am totally ignorant in Ruby programming, hope you don't mind if I've a silly suggestion. Regards

"Proof by rearrangement" [probably Pythagoras's method] avoids any algebra or calculations - it's just "drawing"... The first example is by far the simplest! [image: Pythag_anim.gif] [image: 220px-Pythagoras-2a.gif] [image: 220px-Pythagorean_theorem_rearrangement.svg.png]

Most of the time I get also get 'full-paths' returned. Just occasionally they revert to the short DOS form. This can occur in the same model with the same 'other plugins' loading and the same paths used... It's not a big issue - often the short-path form works well anyway... and the posted code does return the full-path from the short-form if it's needed...

@unknownuser said: hi there again. where would i find help or a compendium that helps me selfteach how 2 generate a working script?! i thind your could be a great base for what i want! Find the free PDF on the www called Automatic-SketchUp... Also get simple a few scripts [there are hundreds!] and read them in Notepad/Notepad++ to see/learn what they do. Also the learn the API = https://developers.google.com/sketchup/docs/ There are also several excellent resources in the Developers' section of SCF... Learn to use the Search tools...
