Topic: Explode a Hatch

[Lupo76]

Hello everyone,
I have always used this function to explode an object and obtain a selection set with nested objects.
Unfortunately today I realized that does not work with entities HATCH.

Can anyone help me?

Code: [Select]

(defun VxExpode (Ent / CurObj CurSet ObjLst)
  (vl-load-com)
  (setq CurSet (ssadd))
  (setq CurObj (vlax-ename->vla-object Ent))
  (setq ObjExp (vla-Explode (vlax-ename->vla-object Ent)))
  (setq ObjLst (vlax-safearray->list (vlax-variant-value ObjExp)))
  (foreach memb ObjLst
    (setq CurSet (ssadd (vlax-vla-object->ename memb) CurSet))
  )
  (entdel ent)
  CurSet
)

A hatch object doesn't have the explode method. One of the many strange things about VL. But you can just use the explode command. This works on BricsCAD:

Code: [Select]

(command "_.explode" ent) ; No need for Enter if explode is called from a Lisp routine.
(ssget "_P")

I knew a guy that exploded a hatch once...once.

I think he was married to a gal I worked with, who exploded and flattened a 3d model...once.

When designing ceilings you often start with a hatch pattern to find the ideal (position of the) grid but later explode the hatch because there are too many interruptions in the grid (lighting, air vents etc.). This approach works well. So IMO exploding a hatch can make sense and is not always something to be frowned upon.

Yeah ... I suppose there is some merit in edge cases. At least it's not like exploding dimensions! 

But I still feel the explode command should only be allowed for those who "know what they're doing". I get all nauseated when I remember how many times I've seen someone explode something like a title block and then want to know why they lost all the text and can't edit text normally instead of through that dialog when they double click the attdef's!
