SUMMARY

The Delete operator uses the Delete POP internally to remove (or keep) packed points (instances) using 5 methods found on the Attribute, Thin, Pattern, Group and Bounding pages. On the Attribute page you can delete based on the values of point attributes. On the Thin page you can delete based on parameter-defined ranges, steps or randomly. You can delete based on patterns using Pattern Matching on the Pattern page. You can delete based on point groups on the Group page. You can delete based on bounding ranges on any attribute on the Bounding page.

Four of the methods let you build the logic using sequential blocks of parameters. For example on the Attribute page, one block selects P(0) > 0 and another that selects P(1) < 0 and ANDed together they will delete packed points in a quarter of the space.
