RESOLVED: boolean SOP documentation

windows pro 16299
touch 2017.14620

I can’t seem to close extruded shapes for a boolean operation like explained in the boolean wiki page.
BooleanSOP says ‘object is not closed’

wiki reference:
derivative.ca/wiki088/index … oolean_SOP
extruded_boolean.toe (4.29 KB)

It seems the missing piece here for extruded geometry is a Facet SOP set to consolidate points and orient polygons before the Boolean SOP (not just after which the wiki mentions to deal with unshared edges / normals.) As such, I presume that’s what ought to be added to the Wiki.
Tested this on the latest 099 as well as a few different builds of 088 for good measure to see if the behavior had changed --not in the past few years anyway if it has.

The powerful yet persnickety Boolean SOP is just dying to have an OP snippet added for it as well to demonstrate the common use cases and precepts detailed in the documentation.

Here’s a simple example TOE anyway for now that deals with an extrude SOP, Boolean SOP, and friends.

Hope that helps.

Sorry it took me a while to come back to this issue.
You example is really great, thanks! They should include it in the snippets :slight_smile:
