Great! I've been waiting for this one ever since 'Slicer2' !!!

No seriously what does it do,... info ?

plot-paris · 12 Jun 2008, 07:38

what is it doing? sounds a bit like Zorro...

tomislavm · 12 Jun 2008, 07:57

sketchup model slice in parts by x or z or y.

tomislavm · 12 Jun 2008, 08:10

another one

That's pretty fance
good for creating abstract models

Zorro is Whaat
And not exactly the same

This one is one my site since October 2007...

oh my god, this is really great! and thanks for the demonstration

just imagine how easy it is to create a terrain model now. simply print out the sliced outlines and cut them out of a foamboard...

thanks a lot. I will definitely find it very useful!

bump!

I can't believe what is capable with a free 3D program like sketchup and the amazing scripts people are giving away!
Several years ago I bought Rhino just to do some slice modeling. Wow!
Thanks so much for this great plugin.

Why is slicer not finishing some of the slices? The shape was made with bezier curve and fredo's cuviloft function then slicer.

I can't be sure without having the SKP itself.
Can you please purge and then post the SKP in question, so I can run some tests on it pre/post Slicing...
If it's 'confidential' then attach it to a PM to me...

Thanks Tig! Here ya go.

My initial look through this finds no issues with the SKP OR with Slicer itself... BUT it DOES miss out vital edges in some random slices whatever settings I try too - which [at the moment is inexplicable, and] I am looking at
I'll continue looking and report back... any one else who wants to chip in please do... I am currently at a loss............

The problem seems to be that the built-in AND API's 'intersect' method fail to intersect a seemingly coplanar face with a cutting plane.
Try this by hand to see that you cannot cut an intersected loop through some faces... the error occurs at a few non-triangulated faces as I show in the image... IF you triangulate the problem facet then the problem doesn't occur
Similarly IF you use my triangulate tool on ALL of the faces [selected inside the object], THEN when using Slice it works fine... therefore it seems a weirdness in the 'intersect' method not taking a quad face as cutting as it is perhaps not quite coplanar in its 4 edges... BUT it is thought coplanar enough to be considered one face when it's NOT triangulated and so it exists and display OK ??????

lapx · 6 Mar 2011, 22:57

Tig your are a genuis! I'm not familiar with your triagulation tool but I'll look into it.
I hope its as simple as selecting all faces and executing the command

Thanks for the help Tig!

lapx · 6 Mar 2011, 23:05

Tig again, I must thank you! It worked like a charm.

TIG · 6 Mar 2011, 23:07

I have reported the weirdness to the powers that be at Google - it is certainly reproducible although I had never seen it before... Meanwhile the temp fix 'Triangulate Faces' is here http://forums.sketchucation.com/viewtopic.php?p=175613#p175613 for the rest of you...
