Special closed polyline filters? |
|
|
I thought the following was good but it's not:
(ssget "x"
'((-4 . "&")
(70 . 1)
)
)
I'm trying to select only closed polys -- light or heavy. The old ellipses
are okay (pellipse = 1) but only the None and Fit, not the Quadratic or
Cubic.
Can someone help with a proper set of filters?

This seems to work:
(ssget "x" '((0 . "*POLYLINE")(-4 . "<OR")(70 . 1)(70 . 3)(70 . 4)(70 .
129)(70 . 131)(70 . 132)(-4 . "OR>")))

(SSGET "X" (LIST (CONS 8 "0")'(0 . "POLYLINE,LWPOLYLINE")'(-4 . "&")'(70 . 1)))
I think Paul T. posted this once.

forget the layer (if you want).

As long as we're on the filter-optimizing kick, I liked the wildcard usage
(SSGET "X" '((0 . "*POLYLINE") (-4 . "&") (70 . 1))) |

Interesting, I'm just the opposite. I prefer to specify
each entity type.

Sometimes you see some clever tricks to abbreviate filter lists. I liked
this one just because it reduced the verbosity in specifying both flavors of
plines -- spelling them out wouldn't make it any more clear for me.
Wildcards are frequently useful for me in filtering for block names, only
because we use highly consistent naming conventions. When I do a trick like
that, I'll add comments elaborating on my block name assumptions. So
ultimately it doesn't reduce the total amount of text in the lisp, but it
slims down the code itself. |

The only problem with the wildcards is if Autodesk
introduces new entity types it may cause you some
unwanted selection set filtering.
You may need to go back and revise *all that code*
to make them behave as they were intended. OTOH,
you could also say the same for wanting the new types
included in the selection set.
6 one way, half a dozen the other.

I agree on both counts. If I'd been using '(0 . "*text*) to include mtext,
God only knows what some of those those functions would have done with rtext
when it appeared. Got any inside leads on new kinds of plines coming down
the pike? :-) |

If I told you, I'd have to kill you ;)
Seriously, I know nothing about any new polylines.

It does, indeed. I created a test drawing with a variety of 16 entities
including plain lines, arcs, circles, regions, heavy polys, and light polys.
Your snippet caught all 9 correct ones. My notes said that okay codes are
1, 129, 131. Not okay are 128, 133.
How did you derive the 3, 4, 131 and 132?
Most Grateful, Len

Your code fetched 2 heavy and 1 light polylines of possible 3 heavy and 6
lights. I thought you'd like to know.
Thanks, Len

Your code got 5 heavy and 6 light polys of possible 3 heavy and 6 lights. I
suspect the 2 extra heavies were the quadratic and cubic ones.
Thanks, Len.
