Exploding a hatch |
|
|
Hi,
If I use code to define and create a hatch, I can explode it by virtue of it
being the last object in the drawing by using a Sendcommand
"EXPLODE L "
However I would far prefer to explode it directly.
Can any one point me to how to explode a hatch with VBA?

As far as I know, you can't explode a hatch with VBA.
If you use SendCommand, it would be more robust
to pass a LISP expression like
(command "._EXPLODE" (entlast))
(entlast) gives you the absoilute last entity regardless
of whether its visible or not.

Hi Tony,
That was the sad conclusion I'd reached.
I'll take your advice about passing the lisp command.
It's still going to be easier to create the hatch, explode it and use the
resultant entities to find a regular series of locations inside a closed
polyline, than to do the "is point inside" type exercise.

Laurie,
I posted some code a while back for someone
that needed to find the rotation angle of a hatch that
is attached to a rotated object. I iterated acad.Pat
for my data. Don't know what you need to do but
the idea might help.

Hi Paul,
The functionality is used in CADApps Landscape program.
The user selects a closed polyline and the program draws tree blocks inside
the polyline. To avoid all the computations of block location and checking
that the location is inside the polyline, I hatch the area, explode the
hatch and then get the locations of the resultant lines to insert the trees.
A 'tree appearance' hatch is not viable for this for a variety of
reasons.inclusive of "planting" the blocks on a Land Desktop (or in due
course) a Civil 3D DTM and randomising the block appearance.
I looked at your code for reading the "Acad.pat" file and admire the work
you put into this. But for my case, the file data is irrelevant, as it is
the locations of the items in the hatch that I need.

I think if I had forgotten to add the rotation of
the first entity in the hatch when printing the
angle. Sorry it didn't help anyway.
Good luck with your project.
