Get Geometry/Object from selected points?

[akirasun]

Hi guys

Is there anyway to get a whole geometry/object from selected points/primitives?

I have tried “group” SOP , but it seemingly only can transfer points <-> primitives bidirectionally(Edit Tab)

Thanks in advance

here is one possible procedural solution

for non-procedural there is Select Connected Geometry option

select_pieces_by_points_or_prims.hip

How can we do this in Houdini 14, because the "Group Mask" of the Blast SOP is not there anymore!

I tried to use the Delete SOP, but there is something wrong.

What do you mean? I see a Group parameter on the Blast SOP.

The easy way to create connected groups procedurally is to append an Assemble SOP. The harder way is to look at how the Connectivity and Partition SOPs are used inside it.

Yes, there is a "Group" parameter, but there was a "Group Mask" parameter too, it's been removed in Houdini 14 .

 

I'm using an assemble SOP of course, then I tried to use "Delete By Expression" in the Delete SOP, but I get an error..

eh?- that is a custom parameter - you can simply add it to blastSOP in H14 if you like it.

Well, now I feel stupid 

just started with Houdini.
