Topic: (100 . "AcDbAlignedDimension") in ssget fliter

[roy_043]

Or:

Code: [Select]

(ssget "_A" ((0 . "DIMENSION") (-4 . "&") (70 . 1)))

Unfortunately, DXF group 70 for dimensions is not truly bit-coded - I believe your code would also select Diameter & Angular 3-Point dimensions, in addition to Aligned dimensions.

Right, I should checked the documentation. It is a group code with a 'history'.
Strange that AutoCAD doesn't support filtering for group code 100.

Alternative filtering for gc 70:

Code: [Select]

(ssget "_A" '((0 . "DIMENSION") (-4 . "<NOT") (-4 . "&") (70 . 7) (-4 . "NOT>")))                     ; 0
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 1) (-4 . "<NOT") (-4 . "&") (70 . 6) (-4 . "NOT>"))) ; 1
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 2) (-4 . "<NOT") (-4 . "&") (70 . 5) (-4 . "NOT>"))) ; 2
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 1) (-4 . "&") (70 . 2)))                             ; 3
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 4) (-4 . "<NOT") (-4 . "&") (70 . 3) (-4 . "NOT>"))) ; 4
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 1) (-4 . "&") (70 . 4)))                             ; 5
(ssget "_A" '((0 . "DIMENSION") (-4 . "&") (70 . 2) (-4 . "&") (70 . 4)))                             ; 6

Interesting approach roy

thank you for all replies

my program will handle aligneddimension and rotateddimension in two diff. ways ,and don't accept other dimension types, so I think using ssget's fliter is not a good way for my goal.

I just feel strange about AutoCAD don't support filtering for group code 100.

I'm using "member" to get the dimension types.

BTW, Lee, you'r very very famous in Chinese lisp writers
