I find there's no such hou.Geometry().addprim() method, and only hou.Geometry().merge(geometry), which can merge two geometry, but what if I want to merge a primitive to a geometry or construct a geometry with a primitive, is there any way to do that?
Thanks.

what kind of primitive you want to create? for polygons there is:
hou.Geometry.createPolygon()
hou.Geometry.createPolygons()

there is a few others for packed, nurbs, volume, …
