Exposing transform edit handle into HDA Dec. 29, 2021, 6:47 p.m.
Hey All,
I'm curious if there's a way to expose the handle of an Edit (or any transform) into an HDA. So that when a user selects the points created, and hits "Enter" or "T" the transform will be placed inside of the defined edit node, and not create a new one.
What I'm attempting to do, is allow a user to select a point that is created inside of the HDA, and then query this point's position to be used inside of the HDA.
I've attached a simple HDA which just has an Add and Edit nodes.
Any help would be appreciated.

Boolean Subtraction | Unwanted primitives being removed Dec. 26, 2021, 7:01 p.m.
Hey All,
I'm having a little bit of trouble getting a basic boolean subtraction operation to work. I've set up a simple grid of blocks and am subtracting a primitive cube from it.
The issue is that when I add an offset/spacing to the blocks, the boolean operation will seemingly start to remove random primitives that are outside of the bounds of the cutting primitive.
Any help figuring out what's going on here, or how to resolve it would be appreciated.

PolyExtrude along curve Dec. 20, 2021, 6:07 p.m.
I'm currently trying to figure out how the PolyExtrude node when plugging in an input curve.
I'm currently expecting the extrusion to follow the curve in local space relative to the primitive normal.
However, this does not appear to be the case, as I appear to get some sort of rotational offset. I can fix this offset by using the "Transform Extruded Front" and manually snapping the "front" prim to the end of the curve, however, it only works along one plane, and not in the other planes, which means that as a procedural workflow, it would very easily break.
I understand that I can probably get a similar result with a different node combo (ie Sweep/PolyWire), but am more curious about how Houdini is applying this extrusion.
